Chromium plating is a common surface treatment technique extensively applied in industry due its excellent properties whichinclude substantial hardness, abrasion resistance, corrosion resistance, surface color, and luster. In this study, the effect of MoS2particles of the composite coating was investigated. To improve the lubrication of mold, Cr-P-C/MoS2 composite plating wasstudied by varying the MoS2 content. The current efficiency of the composite plating incorporated MoS2 particles wasincreased at MoS2 contents of 0.5 and 1.0 g/l due to the incorporation of fine particles. On the other hand, when the contentof MoS2 is 1.0 g/l or more, the current efficiency is lowered due to an increase in impact on the cathode surface. In order toevaluate the mechanical properties of Scratch test were conducted. Scratch test confirmed the lubricity and abrasion resistancecharacteristics revealed that the composite plating with added MoS2 had relatively low surface roughness and uniform surfacemodification to improve its properties.
