Abstract

In order to improve the surface properties and extend service life of pure copper. Siliconizing of copper was carried out by penetrating silica powder. Three new phase were formed in layer, they are Cu0.83Si0.17, Cu9Si, and Cu6.69Si, respectively. The highest micro hardness of the layer reaches up to 340HV0.05, which is 5 times higher than the substrate. The corrosion resistance and oxidation resistance of copper after siliconizing in different solution were studied, such as, the corrosion resistance have improved 2.3 times in H2SO4 solution, 3.8 times in NaCl, and 4.4 times in artificial seawater separately. The oxidation resistance of the siliconized copper is 18 times than that of pure copper. The above experimental results show that, the siliconizing layer will improve the performance of pure copper dramatically.
