阅读说明：本技术 钝化剂、金属镀件表面钝化处理方法和金属工件 (Passivating agent, metal plated part surface passivation treatment method and metal workpiece ) 是由 刘国平 于 2017-07-03 设计创作，主要内容包括：一种钝化剂及金属镀件表面钝化处理方法,以1000重量份计,该钝化剂包括按照重量份数配比的下列成分：2-15份钨酸钠,0.5-3份磷酸二氢钠,2-8份高氯酸钠,1-5份乙酸和余量的蒸馏水。上述钝化剂形成的保护膜层对金属及镀层具有很强的钝化性和抗氧化、防腐蚀能力,干燥后在镀层表面形成无色透明的坚固保护膜,具有耐温、耐盐、耐蚀的性能,可广泛应用于各种金属镀件,尤其对镀镍层钝化更佳。(The passivating agent and the surface passivation method of the metal plated part comprise the following components in parts by weight, wherein the components are calculated according to 1000 parts by weight: 2-15 parts of sodium tungstate, 0.5-3 parts of sodium dihydrogen phosphate, 2-8 parts of sodium perchlorate, 1-5 parts of acetic acid and the balance of distilled water. The protective film formed by the passivating agent has strong passivation property, oxidation resistance and corrosion resistance on metal and a plating layer, forms a colorless and transparent firm protective film on the surface of the plating layer after drying, has the properties of temperature resistance, salt resistance and corrosion resistance, can be widely applied to various metal plated parts, and is particularly better for passivating a nickel plated layer.)
