本厂某产品的簧片和壳体,是用锡磷青铜及08—GB710—65冷轧钢板为基体的电镀件。电镀后的成品要经过冲压及铆凿敲打,故对电镀工艺的要求较高。1981年3月我们开始试验镍铁合金电镀新工艺,先经20升小样试验,于81年3月在上海轻工业研究所通过盐雾试验后(5%中性氯化钠水溶液,温度35℃,时间96小时,镀层未变化)。然后在上海市新苗电镀厂进行了400升镀液的生产 Our reed and shell of a product, is the use of tin phosphor bronze and 08-GB710-65 cold-rolled steel as the substrate of the plating pieces. After plating the finished product to go through stamping and riveting chisel beat, so the plating process higher requirements. In 1981 March we began to test the new nickel-iron alloy plating process, the first 20-liter sample test, in March 81 after the Shanghai Institute of Light Industry through salt spray test (5% neutral sodium chloride solution, temperature 35 ℃, time 96 hours, plating did not change). Then in Shanghai Xinmiao electroplating factory for 400 liters of bath production
