Abstract

파라디움, 파라디움-니켈 합금 및 티타늄 피막으로 형성되는 표면을 가진 제품을 200-400g/1의 불화수소 암모늄, 25-75g/1의 질산 암모늄으로 조성된 박리욕에서 온도 25℃에서 양극 전해로 제품 표면의 금속 피막을 제거하는 박리방법으로 특히 300g/1의 불화수소 암모늄, 50g/1의 질산 암모늄 조성액이 좋다.The product surface having the surface formed of palladium, palladium-nickel alloy and titanium film was subjected to anode electrolysis at a temperature of 25 ° C. in a stripping bath composed of 200-400 g / 1 ammonium hydrogen fluoride and 25-75 g / 1 ammonium nitrate As a peeling method for removing the metal film, the composition of 300 g / 1 ammonium hydrogen fluoride and 50 g / 1 ammonium nitrate is preferred.
