A new process for the production of copper-coated MoS₂ powder is developed through numbers of technical researches for the coated powder production that would be available as raw materials in the powder-metallurgy. The process mainly consists of making activated surface on fine MoS₂ powder and plating copper on it by substitution.
The sintered bronze bearing which contains a small quantity of this copper-coated MoS₂ powder improves a considerable frictional performance. Strength of sintered bronze bearing added this copper-coated MoS₂ powder by 10% is fully enough. This new type of sintered bronze bearing which contains copper-coated MoS₂ powder (50% Cu) by 5% can be commercially produced.
