THE EFFECT OF ELECTROLYSIS PARAMETERS AND SEALING METHODS ON A.C. ANODIZING OF LY12 AND ZL105 Al ALLOY
电解规范与后处理对LY12和ZL105铸铝合金交流氧化的影响

The effects of current density, temperature, anodizing time, stirring intensity and sealing methods on A.C. anodizing of LY12 and ZL105 aluminium have been studied by the measurement of film thickness, corrosion resistance, microhardness and sealing power, etc. It is clear that the properties of anodizing films of LY12 and ZL105 can be improved by suitable selection of electrolysis parameters. The microhardness of two kinds of Al alloy reaches more than 400 Hv, simultaneously and the effects of some ions is also studied.
