PURPOSE:To enable a uniform distribution and to form a tough sprayed film having superior corrosion resistance, oxidation resistance, heat resistance and wear resistance by manufacturing particles consisting of an Ni-P alloy and silicon carbide or silicon nitride united to one body by mechanical combination. CONSTITUTION:To Ni-P alloy powder adjusted to <=100mum particle size is added silicon carbide or silicon nitride adjusted to <=44mum particle size by 0.5-30wt% of the total amount. This powdery mixture is put in a ball mill and mixed with stirring. Strong impact is applied to the mixture through balls, so powder for spraying consisting of the Ni-P alloy and the silicon compound united to one body by mechanical combination is obtd. |
