Abstract

The application provides a method and device for detecting wear resistance of materials, which relate to the technical field of material performance testing. The second characterization data, by processing the first depth image in the first characterization data and the second depth image in the second characterization data, obtain the friction and wear surface topography feature map corresponding to the experimental material; according to the first characterization data The energy spectrum information in the energy spectrum information and the energy spectrum information in the second characterization data, the element transfer sequence of the experimental material is obtained; according to the friction and wear surface topography feature map and the element transfer sequence, the wear feature vector of the experimental material is obtained; by comparing the experimental The wear characteristic vector of the material and the wear characteristic vector of each sample material are used to determine the wear resistance of the experimental material. It is used to solve the problem of low accuracy in determining the wear resistance of materials.

Description

technical field [0001] The present application relates to the technical field of material performance testing, and in particular, to a method and device for testing the wear resistance of materials. Background technique [0002] During the operation of the machine and the movement of objects, friction and wear will inevitably occur between the materials in contact with each other. Under normal circumstances, friction and wear between materials will lead to deformation of the material, affecting the service life of the material, and then affecting the normal operation of the machine or the normal use of the device. Excessive wear of the brake pads may lead to brake fatigue, brake jitter and abnormal noise, damage to the brake disc, damage to the brake drum, or even brake failure. [0003] In the current technology, a single-mode friction and wear testing machine or a multi-functional friction and wear testing machine can be used to test the wear resistance of the material, o...
