The objective of this study was to examine the corrosion characteristics on the copper coating on SUS 304 corrugated metal gasket electroplating. The corrosion process on the gaskets coating surface generates an oxide coating which affects the gasket quality both in the decorative aspect and the performance of the SUS 304 corrugated metal gaskets. The experiment method was used in this study. The objects involved consisted of five variants of copper coating thickness of 10, 15, 20, 25, and 30 μm. Each variant consisted of three samples. Analysis on the corrosion was done through the experiment and reference review. The findings show that the 10 μm thickness variant has a near perfect or flawless coating result. The oxide coating formed from the corrosion is not significant. On gaskets with 15 and 20 μm coating thickness variants, copper (I) oxide or Cu2O is formed with a reddish hue characteristic. Meanwhile, on gaskets with 25 and 30 μm coating thickness, two types of oxide coating, namely Cu2O and CuO are formed with a blackish grey hue. The corrosion level is a result of inadequate electroplating process. © 2020 Institute of Physics Publishing. All rights reserved.
