Magnesium is an extreme vivacious metal material, and its alloys which have excellent properties obtain application greatly. However, magnesium alloys without corrosion resistance in different mediums is restricted. According to masses of documents, many methods were used on alloys, but not very obvious. The technology of electroless plating nickel which develops quickly recently is a surface treatment method.The method of electroless plating nickel on AZ91D is studied during consulting relative data: optim...
