In this work, the novel surface modifiion of magnesium alloy AZ91E was realized. A novel hybrid coating made by coining of the oxide and Diamond-Like Carbon (DLC) layer were elaborated and explored to find out is there any improvements in functional properties when compared to chromate coatings.
Brown coatings may indie over active processing solution or a very active surface, such as an alloy high in copper alloying constituent. Copper in the aluminum alloy accelerates the chemical reaction causing a less satisfactory coating in terms of adhesion and corrosion protection.
Question: I have a customer who wants to paint some magnesium parts. I will only provide a list of chemical pretreatments for magnesium, because the details of these pretreatments are beyond the scope of the Painting Clinic.

3.1. Ca-P Bath Component Generally, the calcium phosphate conversion takes place in acid solution, which needs HCl/NaOH solution to adjust the pH of the Ca-P solution. This process is complied for the preparation of the Ca-P bath. In this study, Ca(NO 3) 2 ·4H 2 O (a nearly neutral substance) and NH 4 H 2 PO 4 (an acidic substance) were selected as coating-forming agents.

15/3/2016· Used for all types of magnesium alloy. – Low DC voltage is applied → 5 µm degree of the oxide film layer is formed. – And dark green colors used in the amorphous structure are implemented. HAE treatment – When you use a two‐phase coating on the surface
Magnesium alloys have low corrosion resistance because of their high electronegative potential and the insufficient protective properties of the natural oxide film. Such alloys are protected from corrosion by the appliion of artificially produced inorganic chemical or electrochemical films, in coination with paint and varnish coatings composed of a prime passivating layer and external
