Problems solved by technology

[0004] At present, the surface treatment of magnesium alloys is mainly chemical conversion treatment, also known as chemical conversion; and black chemical conversion is the best base color for magnesium alloys as transparent coatings or black coatings; however, there are few institutions about the chemical conversion treatment of ZK61M magnesium alloys Research, the existing technology is applied on the basis of traditional magnesium alloy phosphating, the special magnesium alloy black conversion scheme is suitable for AZ91D and AZ31B, and they are not compatible with each other; even if it is suitable for AZ91D and AZ31B at the same time, due to the magnesium alloy composition It is not suitable for ZK61M magnesium alloy; ZK61M magnesium alloy material does have great advantages. It is of great research significance to develop the black conversion technology of ZK61M magnesium alloy to meet the related surface treatment requirements of domestic and foreign aviation parts.
