Abstract
The invention provides a surface treatment method for a magnesium alloy hub. The process includes: cleaning a to-be-treated surface of the magnesium alloy hub; blackening the cleaned to-be-treated surface; and laser cladding the blackened to-be-treated surface, wherein a laser cladding mode is a synchronous powder feeding mode, and a coating material is chromium. According to the surface treatment method for the magnesium alloy hub, air holes can be avoided.
