GALLING TESTING SYSTEM

目前的拨款申请寻求对磨损测试系统（GTS）的支持，该系统将允许人们在高温下对涂层和表面进行深入的摩擦学研究。加焊也称为“冷焊”；当一种材料表面与另一种材料表面在高接触压力下滑动时，以如此强的力附着在另一种表面上，以至于其中一个或两个表面的一部分被撕裂，当零件一起滑动时，两个表面都受到损坏。润滑可以减少磨损倾向，但材料的“抗磨损”性能是指其表面清洁和未润滑时的阻力。GTS将用于评估摩擦学和摩擦现象以及磨损机制，同时模拟机械部件的真实环境工作条件，包括不同材料在受控环境中的接触和相对运动。GTS是迫切需要的

The present grant application seeks support for a Galling Testing System (GTS) that will allow one to perform in depth tribological studies of coatings and surfaces at elevated temperatures. Galling is referred to also as "cold welding"; it occurs when one material surface in sliding contact with another, under high contact pressure, adheres to the other surface with such strong force that a part of one or both of the surfaces is torn away, and both surfaces become damaged when the parts slide together. Lubrication reduces galling tendency, but the property of "galling resistance" of a material refers to its resistance when the surface is clean and unlubricated. The GTS will be used to evaluate the tribological and friction phenomena as well as wear mechanisms, while simulating real-environment working conditions of mechanical components including different materials in contact and relative movement in controlled environments. The GTS is urgently needed
