摘要:
为了提高镍铝青铜镀硬铬的结合力，研究了镍铝青铜电镀硬铬技术，通过对该材料镀铬前处理要求及电镀工艺参数的优化，获得了性能稳定的电镀铬镀层。检测了镀层的结合力、硬度等性能，镀层厚度控制在7.6～12.7 μm，努氏硬度不低于895 HK0.1，弯曲法测试表明其结合力极大提高。该工艺与通用镀铬方法相比，镀层起皮、脱落等结合力差的情况得到有效解决，能够满足更高的硬度要求。
Abstract:
In order to improve the adhesion by chromium plating on nickel aluminum bronze alloy, the chromium plating technology of nickel aluminum bronze alloy was studied. Stable chromium plating coating was obtained by the optimization of pre-treatment requirements and electroplating process parameters. The bonding strength and hardness of the coating were test. The coating thickness was controlled within 7.6 to 12.7 μm, and Knoop hardness was no less than 895 HK0.1. Bending test shows that adhesion is greatly improved. Compared with the common chromium plating method, this process effectively resolves issues such as peeling and shedding of the coating due to poor adhesion, and can meet higher hardness requirements
