【Abstract】 Stainless steel fiber_reinforced ZA43 composite was obtained by pressureless infiltration process.The influence of infiltrating time and N 2 protection on infiltrating process and final combination effects are analyzed in this paper.The reseach shows that,with a proper ratio of time and volume,the infiltrating is compelte from the point of macrostructure,and the composite obtained are improved in its stiffness of wear resistance.But how to avoid contaminating the interface between fiber and base alloy needs more studies.更多还原
