GH2132高温合金钢电镀硬铬工艺改进及监管重点
Information Recording Materials（2022）
Abstract
采用通用电镀硬铬工艺,高温合金钢G H2132材料零件电镀硬铬容易发生起皮、脱铬现象.为了解决高返工率的问题,从选择阳极电解除油、改进浸蚀方式、非必要加入预镀镍中间镀层、调整电镀硬铬工艺参数、设计专用工装等方面对G H2132材料零件电镀硬铬工艺进行了改进,并将改进方式模拟批产实验,验证其生产适用性.结果表明,改进方式和对应的质量监管措施,可明显改善G H2132高温合金钢铬镀层的表面质量,并且适用批量生产,既提高了制造质量又提高生产效率,保障零件正常快速流转.
