Summary: | 碩士 === 雲林科技大學 === 材料科技研究所 === 98 === In this study, the thermal spraying was used to deposite the coatings on AZ31
magnesium alloy, the influence of the coating materials on the corrosion of AZ31
magnesium was studied. Aluminum, aluminum-silicon alloy and aluminum-copper
alloy were used as coating materials. High temperature oxidation tests were carried out
at 400 ℃ for 10, 50 and 100 hours. Cross-section microstructure as used to study the
products and behavior for high temperature oxidation. A potentiostat was used to
measure the corrosion behavior of the coating specimens under different solutions, such
as 3.5wt% NaCl and 5wt% NaCl. The microstructure of coatings and substrates was
examined by electron probe X-Ray micro analyzer(EPMA).
