Description

technical field [0001] The invention relates to a modularized friction and wear testing machine and a testing method thereof, belonging to the technical field of friction and wearing testing machines. Background technique [0002] Friction and wear refers to the physical and chemical phenomena that occur when two contact surfaces move relative to each other. It can be extended to salt spray corrosion wear, liquid erosion wear, and indirect immersion wear. In these cases, the frictional movement has concealment and measurement uncertainty, and its hazards are obvious in production. Friction and wear can cause damage to the material contact surface, cracks, and even lead to the failure of the entire system. Studies by relevant research institutions have shown that about a quarter of the world's annual energy consumption is on friction and wear and its incidental effects, resulting in a large amount of waste in the national economy, and four-fifths of the kinematic pair failure...
