不锈钢箔上电镀历来是困难的,这是因为不锈钢箔表面具有一层天然的耐腐蚀、抗氧化的纯化膜,这层纯化膜极薄,很致密,它与基体不锈钢结合坚固,在一般腐蚀介质中很难完全溶解。由于这层纯化膜的存在,导致镀层与底材结合力很弱。本文介绍了厚为50～100微米的1Cr18Ni9Ti不锈钢箔经化学除油、水清洗后,在同一电解液中采用换向电流先阳极活化、
Stainless steel foil electroplating has always been difficult, it is because the surface of stainless steel foil with a layer of natural corrosion-resistant, anti-oxidation of the purification film, this layer of ultra-thin purification film, it is dense, solid substrate with a combination of solid, corrosive medium Difficult to completely dissolve. Due to the existence of this layer of purified film, resulting in a weak bond with the substrate. In this paper, the 1Cr18Ni9Ti stainless steel foil with the thickness of 50 ~ 100μm is chemically degreased. After the water is cleaned, the anode is activated by the commutation current in the same electrolyte,
