Abstract:
X-ray diffraction, optical microscope , Electron-chemical station, hardness tester and etc. were used for the microstructure, combination force, hardness and corrosion resistance properties investigation on the produced with Ni-P and Ni-W-P electroless plating coatings as coated and after heat treatments. The results show that the combination of both kinds of coating with the substrate is good and coatings are with uniform thickness. The coating shows well packed homogenous cells with a certain direction, and with low porosity. Ni-W-P coating starts to crystallize with lower heat treatment temperature. Ni-W-P coating presents better ductility than Ni-P, when the hardness of the coating is higher than 800HV. As well, Ni-W-P coating shows better anticorrosion property under certain corrosive service state.
