<p>The present invention relates to a method to treat the surface of a base formed of a metal vulnerable to surface oxidation such as magnesium, magnesium alloy, aluminum, aluminum alloy, titanium, titanium alloy, copper, and copper alloy. The present invention includes: a step of forming a passivating solution film by injecting a passivating solution onto the surface of a base; and a step of forming a passivating layer through a reaction with the passivating solution by performing heat treatment for 1-30 minutes at a heat temperature of 40-200°C on the surface of the base where the passivating solution film is formed.</p> |
