Preparation and Micrograph of Ni-P Electroless Composite Coatings with Addition of Nano MoS₂

Ni-P alloy composite coatings with addition of nano MoS2 were prepared by electroless plating technology.The effects of kinds of surface agents,addition volume of nano MoS2 particles and original surface roughness of samples on composite coatings were investigated.It is found that CTAB could disperse the nano MoS2 particles in plating solution well.The optimal addition volume of nano MoS2 is 2.0 g/L,and the content of nano MoS2 in composite coating is affected by original surface roughness of samples.
