摘　　要：采用中温酸性化学镀在Q235B钢基体上制备了Ni-Cu-P非晶态合金镀层,研究了热处理温度对镀层结构、硬度及耐蚀性的影响。结果表明:随热处理温度升高,Ni-Cu-P合金镀层由非晶态结构向晶态结构转变;合金镀层的硬度随热处理温度升高先增加后降低;合金镀层经300℃热处理1 h后耐蚀性提高。With the acidic electroless method, Ni-Cu-P amorphous alloy coating was prepared by electrodeposition on Q235 B steel substrate, and the effects of heat treatment on the properties were studied. The results show that with the heat treatment temperature increasing, Ni-Cu-P alloy coating structure transforms from amorphous structure to the crystalline structure; the hardness of the coating reaches largest at 400 ℃, the latter, the filming hardness drops with the increase of temperature; the corrosion resistance of the layer improves at heat trentment temperature 300℃for 1 h.
