Wear Resistance of Electroless Ni-P-SiO_2 Composite Deposits for Cold Working Die Steel

研究了Ni P SiO2 复合镀层的施镀工艺 ;热处理对复合镀层的硬度、耐磨性的影响。试验结果表明 :含SiO2 微粒可明显改善复合镀层耐磨性。

The depositing process and the effect of heat treatment on hardness and wear resistance of electroless Ni\|P\|SiO\-2 composite deposits have been studied. The results confirm that the wear resistance of the composite deposits containing SiO\-2 particles is improved appreciably.
