标准摘要
[中文适用范围]: 第二版取消并取代第一版(即 ISO 2179:1972)。 规定了金属间化合物 SnNi 电镀层的要求,其成分约为 65% (m/m) 锡和 35% (m/m) 镍。 它不适用于螺纹部件、未加工形式的齿条、带钢或线材上的涂层、螺旋弹簧上的涂层、拉伸强度大于 1000 MPa 的钢的电镀。 [外文原描述]: This second edition cancels and replaces the first edition (i. e. ISO 2179:1972). Specifies requirements for electroplated coatings of the intermetallic compound SnNi, with a composition of approximately 65 % (m/m) tin and 35 % (m/m) nickel. It does not apply to threaded components, coatings on cheet, stsrip or wire in the unfabricated form, coatings on coil springs, electroplating of steels with tensile strength greater than 1 000 MPa.
