Functional properties of the novel hybrid coatings coined of the oxide and DLC layer as a protective coating for AZ91E magnesium alloy
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.
Conversion Coatings for Aluminum and Magnesium
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.
