The results show that there are no cracks or breaches between the metal and copper, and these materials completely enclose SUS304. Cracks also do not occur after the gaskets have been used to seal flange leakage. Furthermore, the copper layers are likely to be durable, showing no changes between before and after use on the flange. The performance of coated corrugated metal gasket was better than standard corrugated metal gaskets. | Electroplating process for copper coating of corrugated metal gaskets to increase performance
