摘 要: 通過(guò)NaCl中性鹽霧腐蝕試驗(yàn)定性地分析鎂合金微弧氧化陶瓷層的耐蝕性, 初步研究了陶瓷層表面微觀結(jié)構(gòu)對(duì)其耐蝕性的影響。結(jié)果表明: 鎂合金微弧氧化陶瓷層的微觀組織結(jié)構(gòu)的結(jié)合方式和生長(zhǎng)方式直接影響其耐蝕性, 微弧氧化試樣的耐蝕性與陶瓷的厚度有關(guān), 陶瓷層厚度的增加并不一定能使其耐蝕性提高。

Abstract:The corrosion resistance of magnesium alloy micro-arc oxidization ceramic coating was analyzed qualitatively by 5%NaCl neutral salt haze test. The effect of microstructure of the ceramic coating surface on its corrosion resistance was studied. The results show that bonding and growth mode of the ceramic coating have direct influence on its corrosion resistance.
Key words: magnesium alloy; micro-arc oxidization; corrosion resistance
