| 摘 要： | 分析研究了硬铬镀层气密性不佳的原因。为提高电镀硬铬镀层的气密性,采用一种封孔技术对镀层进行后处理。研究表明,用518封孔剂处理后的硬铬镀层,气密性可满足"20 MPa,30 min气密性试验,铬层不出现渗漏气泡"的要求,封孔剂可进入到镀层20～30μm的深度,且耐液压油性能较好。

| Abstract: | The causes of poor airtight performance of hard chromium plaiting were analyzed. A sealing-treatment was employed in the post-treatment of hard chromium plaiting to improve the airtight function of the coating system. The results showed that the hard chromium plaiting passes 20 MPa/30 min airtight function testing with no leakage of gas after the post-treatment by 518 sealing reagent; the sealing reagent penetrates as deep as 20-30 μm and co-operates well with hydraulic fluid. |
