Abstract

Composite plating is commonly used for reducing
friction and wear. It is a method that can be used in the environments exposed
to friction such as rocket launchers. Steel specimens were coated by nickel
including MoS2 particles in this study. The effects of MoS2 particle
concentration and particle size on the coefficient of friction and the amount
of wear were determined by pin on disc tribometer. It is revealed that the
particles with small size and high concentration are more effective in
decreasing the friction coefficient.

Keywords
