Abstract


This paper presents research on influence of process parameters on the sustainability of the spray coating spraying. We made experiments with the purpose to find out optimal parameters of layer in which to have a better sustainability of mold gain by metal spraying molten. Uniform grain microstructure well sudden between them and high density without oxides lead to better resistance of layer pulverized. The conclusion of good results is the temperature and the speed of particulars at impact moment and cooling condition of layer pulverized  as well  influence the layer’s microstructure and all the mechanic proprieties of the mold gain by pulverized.  

Key words: injection molding, metal spraying, rapid tooling
