The corrugated metal gasket is currently still very much in development. This kind of gasket is essential to replace asbestos gasket, in which the production and usage are now prohibited. One of the development in corrugated metal gasket is the formation of three-layered gasket materials. However, the manufacture of this formation is difficult as the three materials that are formed together cannot strongly bond. The purpose of this research is to form a coating of copper and nickel for SUS304 corrugated metal gasket. The purpose of the coating is to have the outer layer, which is of copper or nickel, to infiltrate the rough surface of the pipe flange, resulted in a much higher contact width. The research also incorporate simulation and experimental work to determine the performance of the coated corrugated metal gasket. Results from the simulation and experiments indicate that the corrugated gasket's performance is improving, which was shown by the increase in contact width and the decrease of leakage from the water pressure test. The increase in contact width was 54% but the contact stress decrease 18% for copper coated 30 μm and contact width was increase 39% but the contact stress decrease 8% for nickel coated 30 μm. The leakage did not occur when axial force 80 kN for standard gasket, 40 kN for cupper coated, and 60 kN for nickel coated when the water pressure test 12 MPa. © 2020 Taylor's University.
