In this study, the optimal condition of surface treatment for aluminum panel was determined by measuring the contact angle and T-peel strength. The contact angle was measured for various mixture ratios of acetylene gas and nitrogen gas. The mixture (acetylene gas to nitrogen gas) ratios used were 1:9, 3:7, 5:5, 7:3, and 9:1. The contact angle was also measured as a function of time of surface treatment. The results showed that the contact angle was a minimum for mixture ratio of 5:5. T-peel strength was a maximum for the treatment time of 30 second.
