文章就27SiMn液压支架用无缝钢管内壁镀镍后，在使用过程中内壁出现的起泡和剥落等缺陷进行了检测分析，经分析其原因为无缝管内壁镀镍前未完全清洗干净，导致镀镍层与内壁局部结合不好，在使用中起泡并剥落。
The bubble and flake defect on the interior face of 27SiMn seamless steel tube for hydraulic support which occurred during working after its interior face nickelplated had been analyzed. The results showed that the incomplete cleaning of the interior face before nickelplating brought about the local loose combining between the nickel layer and the interior face which caused the bubble defect during working.
