Railway rails are designed to endure years of heavy loads and different operating conditions. However, over time, contact forces between the rails and the wheels of trains can cause significant wear and tear on the […]
Wear has major impacts on economic efficiency or health. All movable parts are affected, examples being the bearing of a wind power plant or an artificial hip joint. However, the exact cause of wear is […]
Scientists at the United Technologies Research Center and UConn used advanced additive manufacturing technology to create ‘smart’ machine components that alert users when they are damaged or worn. The researchers also applied a variation of […]
The surface of materials can have an enormous influence on their function. If the external properties are changed, this also expands the range of possible applications. This is why materials scientists at Friedrich Schiller University […]
Research sheds light on friction, lubrication and wear in cartilage 11:25 a.m., Aug. 24, 2015–Osteoarthritis, which affects some 27 million people in the U.S. alone, occurs when the protective cartilage on the ends of bones […]
The Curiosity Rover has made some incredible discoveries during the five years it has been operating on the surface of Mars. And in the course of conducting its research, the rover has also accrued some […]
Food leaves permanent traces on teeth. Cows chewing on grass, tigers tearing up a piece of raw meat and humans munching on tortilla chips all end up with tiny scratches and nicks on the enamel […]
Brandon Krick explores the interdisciplinary science of surface interaction Brandon Krick says he’s had the good fortune to research space and dinosaurs—“all the things you want to explore as a kid,” he says. But his real […]
Forty years ago, MIT emeritus professor of mechanical engineering Ernest Rabinowicz calculated that 6 percent of the annual U.S. gross domestic product was lost through mechanical wear. His assertion gained enough traction that it became […]
Models for the stress-activated growth of tribofilms from ZDDP were modified to include wear. TWO RECENT CUTTING EDGE ARTICLES reported on work that showed the growth rates of tribofilms from ZDDP were accelerated by contact […]
