s This the Most Wear-Resistant Material in the World

s This the Most Wear-Resistant Material in the World s This the Most Wear-Resistant Material in the World Is This the Most Wear-Resistant Material in the World?People love gold for many reasons. Its shiny, valuable, an excellent conductor, and doesnt corrode quickly. Gold is also extremely brittle. But when scientists at Sandia National Laboratories mixed platinum with a little gold, they ended up creating what some are calling the most wear-resistant alloy in the world.Researchers at the U.S. national lab mixed 10 percent gold with 90 percent platinum and made an alloy thats up to 100 times mora wear resistant than stainless steel, two to three times more than hard-gold metal alloys, and up to nine times more than gold. The new alloy could be used to make new power-generation systems, engines and other equipment that are long lasting and require low maintenance.Theres nothing intrinsic about platinum or gold alone that drives you to select these like we did, said Nic Argibay, a mate rials scientist and researcher at Sandia. In the right proportion, those two elements could be configured into a microstructure that has remarkable stability.For You Engineering Simulation Provides Real-World Design Benefits and ImprovementsResearchers Michael Chandross (left) and Nic Argibay work on a computer simulation that predicts the wear resistance of their platinum-gold alloy. Image Randy Montoya / Sandia National LaboratoriesPast work on how metals wear and the use of alloys in electrical contacts motivated the scientists to look at the relationship between platinum and gold. Their understanding of how metals interact when sliding or rolling against each other led them to design new materials with superior performance. Inspired by research at MIT, which found that platinum-gold belonged to a class of nanocrystalline alloys with thermal and mechanical stability, Sandia researchers began designing clever ways to increase the stability of particular alloys.We came to understan d that the microstructure and its evolution the grain size and how stable the grain size is is fundamentally and primarily defining the frictional and wear properties of an alloy when it is rubbing against metal, Argibay said.Platinum-gold will improve electrical contacts by reducing cost, increasing reliability, and achieving better performance in more aggressive environments, the researchers said. It could also be used as a coating to address tribological and structural issues in gears, engines, and other engineering products.One impact area we are excited about is next-generation wind turbines that may rely on noble-metal coatings like this to facilitate or obviate the removal of rare-earth metals, he said. You may have a direct-drive wind turbine with electrically energized generators. Instead of having to put expensive, heavy and risky rare-earth metals in rotors, we can enable a different route to design next-generation large wind turbines that are equally reliable to what w e use today, but much cheaper.In the short-term, the alloy could be added to blade-pitch motors and communication slip rings used in wind turbines, which wouldnt need to be opened up and fixed repeatedly. Reduced maintenance costs, along with the longer life of parts, could offset the high cost of the metals.Even though its an expensive platinum and gold alloy, thats a lot less costly now, Argibay said. You might start considering using platinum and gold in cheaper commercial products if you need a tiny bit of it.The researchers determined the ratio of platinum and gold that should give the alloy a grain size with better wear properties. The coatings which were one to two micrometers in size, in line with standard gold coatings were synthesized through sputter. The coated steel was put through a friction and wear tester called a tribometer, and connected to a hard, smooth sapphire sphere. Samples were taken after progressively long periods of sliding or cycling wear and researcher s determined the volume lost. A host of characterization techniques were also run to see what areas of the microstructure had worn. The researchers also ran molecular dynamics simulations.The platinum-gold alloy is in the process of being patented. The research is being used as a springboard to find other wear-resistant alloys cheaper than platinum-gold. The researchers also want to test the effectiveness of platinum-gold coatings down to a few hundred nanometers.Read MoreSpray-On Antenna Could Signal the Future of WirelessHow Engineers Close Communication Gaps with Non-engineersEngineers Cook Up New Robots for Hungry Food Industry For Further Discussion One impact area we are excited about is next-generation wind turbines that may rely on noble-metal coatings like this to facilitate or obviate the removal of rare-earth metals.Nic Argibay, Sandia

Biomedical Engineering in Sports Medicine

Biomedical Engineering in Sports Medicine Biomedical Engineering in Sports Medicine Attending the University of Wisconsin-Madison, Jennifer Sanfilippo is working toward a graduate degree in biomedical engineering, specializing in sports medicine. Sanfilippos experience has involved working for high school and university programs and with mechanical engineers, doctors, therapists, and athletic trainers for her research. Sanfilippoholds a B.S. degree in biology and another in athletic training and plans to graduate in May 2011 with an M.S. in biomedical engineering.Falling for Sports MedicineShe recalls how it all began I became interested in sports medicine when I was in high school. Participating in sports myself, in the off season, I would stay involved helping the schools athletic trainer with athletes during the practice season. Coming to Madison, I began my college experience studying in the biology department as a general student with the hopes of continuing in medicine, but as many young students find themselves honing in on specific interests, I eventually moved into the kinesiology department. There I sought a degree in athletic training. While studying, I had the opportunity to work with various athletes on their injuries, following them to away games, and observing different medical professionals reveal their specific expertise. During this time, I realized my true love of research and my unknown desire to become an engineer. Working for my masters in biomedical engineering, I have taken courses in materials, mechanics, statistics, and biology which are all required in my everyday research.The University of Wisconsin Madison Athletic Training Education Program features a strong cocktail of basic sciences, kinesiology courses, and athletic training subject matter. The program features clinical experiences in intercollegiate and secondary school settings. Working directly with school athletes is unique to the Athletic Training program. Every semester, s tudent athletic trainers are assigned to a collegiate team, where they are directly involved in the athletes rehab program. One semester is done at a high school helping with the sports offered for the semester. This provides an exposure to a larger variety of injury types. In biomedical engineering, you can have a variety of experiences at the masters level based on your particular research interests. As my interests are more biomechanically related specifically to orthopedics, I study hamstrings and work directly with the physical therapists and athletic trainers.My personal research is directly related to the injuries themselves. It is very interesting to see how one injured muscle can affect all parts of a persons gait (way of walking) and how the healing process further affects this. Normally, as an athletic trainer, I saw the overall effect, but in my research I am able to see tissue level healing with the help of MRI use. We work on using engineering techniques to analyze inj uries and how rehab directly affects the healing tissues. The mechanical engineering we use is directly involved in data analysis using specialized equipment, we can see when muscles fire, how much force they apply, and which ones do the most work. We use such programs as Matlab to calculate peak torque of specific muscle groups. After analyzing an injured athlete, we help with new rehabilitation techniques and then retest the subjects to determine how well we have cured the injury. I use mechanical concepts at almost every step, starting with proper function of equipment, proceeding with testing forces, and ending with our analysis. If you would like more information about the laboratory I work in along with other research we are currently investigating, follow the link engr.wisc.edu/groups/nmbl/index.html.Many of my colleagues have moved from research to work in academic laboratories, national laboratories such as the National Institute of Health, medical equipment design, compani es such as GE Healthcare, and others. I hope to move into athletic training specifically designing new treatment methods for injuries and stay tied in research while helping athletes at a university.The Move to ResearchIn the past, athletic trainers and sports medicine professionals have worked specifically on athletes, but they are now moving to assist with sports-related research and work for companies as on-staff medical personnel. Also, as the population grows and ages, the need for medical assistance is increasing in demand. With more specialized professionals, people can get the exact help they need without relying on a first visit to a general care doctor.Sports medicine is a growing field, uniting biomedical engineers with sports medicine professionals, allowing the field to advance in materials with the creation of ergonomic prosthetics with biocompatible materials, monitoring systems for recovering injuries, mechanical bracing apparatus for weak joints, and more.It is very interesting to see how one injured muscle can affect all parts of a persons gait (way of walking) and how the healing process further affects this.Jennifer Sanfilippo, University of Wisconsin-Madison
