Description

technical field

[0001] The invention belongs to the technical field of material performance testing, and in particular relates to a material friction and wear performance testing device and a testing method. Background technique

[0002] The friction and wear performance of materials is one of the important indicators to measure the performance of materials. The friction coefficient and wear performance between two materials have an important impact on the reliability of the friction pair they form. The friction and wear properties between materials have important research significance in many fields such as sealing and machining. Among the existing friction and wear testing devices, according to the friction pair, they can be divided into ball-on-disk friction and wear testing machine, pin-on-disk friction and wear testing machine, disk-on-disc friction and wear testing machine, ring block friction and wear testing machine, four-ball friction and wear testing machine, cylin...
