中文摘要:
      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20~30 μm的深度, 且耐液压油性能较好。
英文摘要:
      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.
