Determination of the Optimum Laser Processing Parameters Required to Obtain a Stable Hydrophobic Surface on the Surface of AA1050 Aluminum Alloy

Öz

In this study, the surfaces of sheets made of AA1050 aluminum alloy, which has high aluminum purity and also high strength, were roughened with a fiber laser. The aim of the study is to obtain a surface with a highly stable contact angle. For this purpose, it was aimed to minimize the change in the contact angle with time. Three different laser processing parameters were used. The effects of the laser parameters on the stability of the contact angle were investigated. According to the data obtained as a result of the study, the texture type created on the surface was calculated as the most effective parameter to obtain a stable surface. The rate of influence of the texture type parameter on the result is 61.61 %. The parameter with the least effect on the result was calculated as laser scanned factor with 15.31%. The parameter that moderately affected the result was calculated as laser power with 23.08%. In addition, according to the ANOVA calculations, it was suggested that a more stable surface pattern could be obtained in the experiment with different parameters.
