ENVIRONMENT-FRIENDLY COLOR SURFACE MODIFICATION PROCESS OF METALS HAVING HIGH CORROSION RESISTANCE

摘要

PURPOSE: An environmentally-friendly color surface modification process of metals is provided to produce a material with superior pollution and corrosion resistances with an environmentally-friendly method. CONSTITUTION: An environmentally-friendly color surface modification process of metals comprises a step of carrying out a surface-activating process on a metal material(S10), a step of carrying out a coloring process(S20), and a step of coating a transparent resin film on the colored metal material(S30).
