Electrochemistry coloring is a coloring technique that the stainless steel is immersed solution of CrO_3 and H_2SO_4, and surface generates oxidate coating of Cr, Fe and Ni by electrolysis. Color changes with thickness on film.

• 电化学着色法是将不锈钢浸在成分为CrO_3和H_2SO_4溶液中,通过电解作用,在表面形成铬、铁、镍的氧化物,颜色也随着表面膜厚度的改变而变化,电化学方法着色是未来的发展趋势。
