Method of preparing a magnesium alloy substrate for a surface treatment

摘要

A method of preparing a magnesium alloy substrate for an electroless electro-deposition surface treatment includes cleaning the magnesium alloy substrate in a wet solution, whereby a magnesium hydroxide layer is formed on an outer surface of the magnesium alloy substrate, and heating the magnesium alloy substrate to a temperature sufficient to convert the magnesium hydroxide layer to a magnesium oxide layer.

1. A method of applying a surface treatment to a magnesium alloy substrate, the method comprising:
cleaning the magnesium alloy substrate with a wet solution, whereby a magnesium hydroxide layer is formed on the magnesium alloy substrate; heating the magnesium alloy substrate to a temperature of at least two hundred degrees Celsius (200° C.) to transform the magnesium hydroxide layer into a magnesium oxide layer; and applying a coating of an electro-deposition solution to the magnesium alloy substrate in the absence of an applied electrical charge in both the magnesium alloy substrate and the electro-deposition solution.
