- Metals, Vol. 13, Pages 637: Influence of Precipitation Hardening on the Mechanic... Co-Cr alloys have good mechanical properties such as high hardness, excellent magnetic properties and good corrosion resistance. For this reason, they are most commonly used as dental and orthopaedic implants. Generally, cast Co-Cr-Mo alloys and forged Co-Ni-Cr-Mo alloys are used for the production of implants. In this study, we investigated...
- Southwest Research Institute develops device to test friction, wear associated w... From Southwest Research Institute A Southwest Research Institute team has developed a mechanical testing device to analyze fluids and lubricants formulated for electric vehicles. The team modified a commercial tribology testing device to give it the capability to evaluate the impact of electric currents in fluids, measuring the wear and...
- Tribology of the diamond-silica interface State-of-the-art ab-initio simulation unveils ways to reduce friction and wear Famed for their outstanding mechanical properties, biocompatibility, and chemical stability, diamond and diamond-like carbon (DLC) have found widespread use in industries including electronics, optics, and medical devices. DLC in particular has been employed as a coating to reduce friction and...
- Too fast for friction Slow sliding (left) leaves the structure of the metal intact. Fast sliding (middle) completely destroys the structure. Extremely fast sliding (right) partly melts the uppermost layer, which protects the layers below. Image: TU Wien.When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to...
- Not All Digital Twins Created Equal Much more than a simple 3D CAD rendering, digital twins can significantly advance operational performance. By Mark Childs and Walt Ravelo, GE Digital A digital twin that provides value to the operating capability of a power plant must include physics and empirical-based modeling, product design information, operational data, and failure-based...
- Making surfaces water-repellent with sandpaper A team from Rice University have developed a one-step way to make surfaces very water-repellent, known as superhydrophobic, without using chemicals. Their new approach, which involves sandpaper, some powders and a bit of toil, offers the best properties for superhydrophobicity as well as providing materials with excellent anti-icing properties. As reported in ACS Applied...
- Machine Learning To Play Key RCM Role By Dr. Klaus M. Blache, Univ. of Tennessee Reliability and Maintainability Center (RMC) and Rajiv Anand, CEO, Quartic.ai With so much of what we need to fix attributed to random failure, more sophisticated tools and technologies are needed to enable the best opportunity for early detection and intervention. Understanding this, the...
