Dry Wear Characteristics of MAO Applied on AZ31 Sheet Alloys with % Lanthanum Additions

In this research, AZ31 alloys were enhanced with 0.2% and 0.5% La (Lanthanum) using the low-pressure die casting method. These alloys underwent hot rolling at 400°C with speeds of 4.7 and 10 (m/min) meters per minute, Maintaining a deformation rate of 30% with each pass. Post-production, Micro Arc Oxidation (MAO) has been utilized. The durability against wear of the extracted material sheet samples, each having different surface morphologies due to varying La percentages, was investigated under dry conditions following The ASTM G-133 standard method assesses the sliding wear of ball-on-flat surfaces using a linear reciprocating motion. This study conducted a systematic analysis of how the MAO coating and the addition of La influence wear resistance, supported by microstructure analysis. Keywords: AZ31, La, Wear, Hot rolling, MAO.
