Study on Frictional and Wear Properties of Ag-G/MoS2 Composites in Various Controlled Ambiences

摘要

Ag-G/MoS2 composite brushes were fabricated by means of powder metallurgy method, the frictional and wear properties of composites with different content of G and MoS2 in ambient air and nitrogen are studied, the effect of various controlled ambiences has been discussed. The results show that Ag-G-MoS2 composites express excellent wear behavior in ambience air, as in nitrogen environment, Ag-MoS2 has optimal properties, while Ag-G-MoS2 behavior inferior to it punily. Considering that brushes are required to work with different ambiences, Ag-G-MoS2 of steady properties is suitble.
