一种镁合金工件表面处理方法

Method of treating magnesium alloy work-piece surface

Abstract

本发明提供一种镁合金工件表面处理方法,工艺流程包括工件前处理、化学转化处理、干燥处理以及各工序间的水洗处理。其中,化学转化处理是将镁合金工件浸入由主成膜物质和辅助成膜物质组成的转化液中进行;主成膜物质为锆盐、锰盐、钼酸盐、钨酸盐等过渡金属盐中的一种或几种,换算成Na
The invention discloses a surface disposing method of electron alloys work piece, which is characterized by the following: including work piece fore treatment, chemical transformation treatment, drying treatment and washing treatment of each interprocess; dipping electron alloys work piece into inverting liquid of main filming matter and assistance filming matter as chemical transformation treatment; setting main filming matter as one or several zircon salt, manganic salt, molybdate and tungstate and so on transient metal salt; converting to Na2MoO4íñ2H2O content with density at 5-150g/L; setting the assistance filming matter as one or several nitrate and sulfate of lithium, sodium and potassium alkali metal; converting to LiNO3 content with density at 0.5-20g/L and pH value of inverting liquid at 2-6; controlling the disposing temperature at 10-90 deg.c and disposing time at 5-30 min. This surface film possesses properties of protection and decoration.
