The objective of this study is to compare two methods measuring the coating thickness of electroplating copper coating on the austenitic stainless-steel substrate. The electroplating was carried out in a solution containing 200 g/L CuSO4, 100 g/L H2SO4 at room temperature and current of 40mA/cm2 during 20,40,60,80 and 100 mins as coating periods.

The results show that at 20 mins coating time interval, the thickness measured by cross sectional method was 16.67 µm and by weight gain method was 17.37 µm, with difference of 0.7 µm and percentage error of 4.11%. This error increased to 5.27% at 100mins time interval, where the values of the thickness measured by cross sectional and weight gain were 86.33 µm and 81.9 µm respectively, and the difference was 4.43 µm.
