摘要
采用自制的脉冲电镀装置对15-5PH不锈钢电镀铬层进行研究。结果表明,在标准镀铬液中,镀液温度为55℃,平均电流密度70 A/dm2,在占空比30%的条件下,随频率升高,镀铬层致密度增大,产生微裂纹的倾向性减小,表面粗糙度降低。但当频率大于3.0 Hz时,镀层致密度降低,产生裂纹的倾向性增大,表面粗糙度升高。
The chromium electrodeposits on 15-5PH stainless steel were studied using special pulse planting apparatus. The results show that the chrome layer density increases, the cracking tendency reduces and the surface roughness decreases with the increase of pulse frequency when the bath temperature, the average current density and the duty cycle are 55℃ 70 A/din2 and 30%, respectively, Htowever, the coating density decreases, the cracking tendency and the surface roughness increase when the frequency is higher than 3.0 Hz.
