ABSTRAK

Magnesium is widely used due to its low density high strength good weldability and castability properties. However magnesium has several weakness such as poor corrosion low wear and creep resistance and also high chemical reactivity. Coating is a method to protect the material from its weakness. The aim of the research is to analyze the influence of weight percentage of alumina gamma - Al2O3 during deposition Algamma - Al2O3 composite layer on magnesium surface. Powder flame spray method was used to deposit the composite to the substrate. Percentages of the gamma - Al2O3 composition on the composite was varied from 0 to 40. The investigation of the morphology was conducted using SEM and EDX. From morphology investigations show that the composition of gamma - Al2O3 affects to the density and thickness of the film. The optimum weight percentage of alumina gamma - Al2O3 is 20 wt.
