전해크로메이트 피막의 표면외관에 미치는 용액중 불순물의 영향
Effect of impurities in bath on surface appearance of electrolytic chromate film
초록
The surface appearance of zinc coating chromated electrochemically was investigated with the concentration of impurities in chromating solution. The chromium content and yellowness of chromated film decreased with more than 0.1g/1 Zn in chromating solution, while white ness of it increased slightly. The chromium content and whiteness of chromated film also decreased with more than 0.1g/1 Fe in chromating solution, but the yellowness of it increased. Chromium content, whiteness and yellowness of chromated film decreased slightly with more than 0.5g/1
