主要研究了桥梁支座球冠衬板不同的化学镀镍磷工艺路线,结果表明当基材粗糙度Ra≤0.12 μm、磷含量12%、施镀4 h后进行钝化处理为球冠衬板最优的工艺路线,同时发现不同热处理工艺和基材粗糙度对化学镀镍磷镀层硬度、耐蚀性都有影响,当热处理温度为200 ℃时,镀层硬度有少许增加,耐蚀性能无变化;当热处理温度为360 ℃时,镀层硬度明显增加,耐蚀性能下降明显,基材粗糙度Ra≥1.6时,镀层耐蚀性能下降明显.
Study of chemical Ni-P plating technology on bridge bearing spherical calotte
Mainly studied different chemical Ni-P plating process routes on bridge bearing spherical calotte.The results show that when the roughness of base materials Ra≤0.12 pm,P content is 12%,plating time is 4 h,the process route is the best rout,and different heat treatment process and roughness of base material would affect chemical Ni-P plating's hardness,corrosion resistance and thickness measurement.When heat treatment temperature is 200 ℃,plating become more harder slightly,corrosion resistance no change.When heat treatment temperature is 360 ℃,plating become more harder obviously.Corrosion resistance become more worse obviously.When roughness of base materials Ra≥1.6,corrosion resistance become more worse obviously.
