Reduction of the Friction Coefficient of Metal Matrix Composite Under Dry Conditions 870441
A Silicon carbide (SiC) whisker reinforced Metal Matrix Composite (MMC) with dispersed self-lubricating tungsten disulfide (WS2) exhibits a reduced friction coefficient under dry rubbing conditions.
The new MMC production method was done by impregnating a molten aluminum-tungsten alloy into a preform, which was made from a mixture of SiC whisker and sulfur compound, at high pressure. The high temperature allowed a reaction between the tungsten and sulfur compound, and the formation of WS2 in the MMC.
