Description

Technical field [0001] The invention belongs to the technical field of material processing and wear, and in particular provides a high-temperature sliding wear and thermal contact fatigue material testing machine. It is suitable for sliding wear and contact fatigue tests between materials under high temperature conditions. Background technique [0002] (1) Among the existing wear and fatigue testing machines, there is no relative sliding wear and contact fatigue testing machine between materials at high temperature (850-1000°C), especially under hot rolling conditions, the impact of forward sliding and lubrication on high temperature Sliding wear, thermal contact fatigue influence test. [0003] (2) There are many types of wear testing machines available. These testing machines are mostly used to measure the coefficient of friction under different lubrication and temperature conditions. The common ones are disc-type testing machines, four-ball friction testing machines, and...
