金属及其他无机涂层.镍,镍加铬,铜加镍和铜加镍加铬电沉积涂层

[中文适用范围]： 本国际标准规定了应用于铁、钢、锌合金、铜及铜合金、铝及铝合金上的装饰性镍、镍加铬、铜加镍和铜加镍加铬镀层的要求，以提供吸引人的外观和增强的耐腐蚀性。规定了不同的厚度和类型的镀层标识，并提供了根据镀层产品将暴露的服务条件选择适当镀层标识的指南。本国际标准不规定基材在镀层工艺前所需的状态，也不适用于非成型状态的板材、带材或线材上的镀层，以及螺纹紧固件或线圈弹簧。塑料材料上的装饰性电镀铜加镍加铬镀层的要求规定在ISO 4525中。ISO 4526和ISO 6158分别规定了工程用途的镍和铬镀层的要求。 [外文原描述]： ISO 1456:2009 specifies requirements for decorative nickel, nickel plus chromium, copper plus nickel and copper plus nickel plus chromium coatings that are applied to iron, steel, zinc alloys, copper and copper alloys, and to aluminium and aluminium alloys, to provide an attractive appearance and enhanced corrosion resistance. Coating designations are specified that differ in thickness and type, and guidance is given on selecting the coating designation appropriate for the service conditions to which the coated product will be exposed. ISO 1456:2009 does not specify the surface condition required by the basis metal prior to the coating process, and is not applicable to coatings on sheet, strip or wire in the non-fabricated form nor to threaded fasteners or coil springs.
