Abstract��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 nickel��plated had been analyzed. The results showed that the incomplete cleaning of the interior face before nickel��plating brought about the local loose combining between the nickel layer and the interior face which caused the bubble defect during working.
