Tribological characteristics of dispersed-filled composite materials
摘要
The article presents the results of laboratory tests of dispersed-filled composites. Tests on friction and wear were performed using “disk - pad” and “rotating bushing on disk” schemes. There is high compatibility of materials in friction pairs of composite material and steel and their advantages over a pair of bronze and steel in terms of wear and maximum working load, and also stability of the coefficient of friction in operation mode, and also stability of the latter as the load increases. It is shown that the increase in size and volume content of particles in the matrix reduces wear of parts of composite material, however, this increases the wear paired counterface and friction coefficient.
