Abstract

The effects that processing atmospheres and alloy composition have on the wetting characteristics of Al-Mg alloys on the SiO2 substrate were investigated by measuring the wetting angles. It was observed that the wetting behavior of the Al-Mg alloys on the SiO2 substrate vary depending on the Mg content of the alloys and atmospheres. The results showed that the contact angle decreases with increasing Mg content, angle is generally larger in the N2 atmosphere than in the Ar atmosphere. We discussed the validity of the results obtained from the wetting test on the basis of recent theories and the results observed from the actual penetration tests.
