随着电刷镀工艺的逐步推广与应用,已经由机械设备的维修开始向产品生产工序中扩展,成为重大、关键产品延长生产检修周期的重要工艺手段之一。针对水电产品部件重、面积大、工况环境恶劣的特殊要求,对镀层除要求有防腐性能外,在机械转动部位还要求具有一定的耐磨性能,特别是液压部位的零部件,既防腐又耐磨是水电产品的特殊要求。过去错误的认为:油压闭封部位经常处于有油膜保护状态,不会腐蚀,大多不采用防腐措施。但是,在实际工况运行时,尤其在停机检修期间,会失去油膜保护,这时基材会遭到不同程度的腐蚀,
With the gradual popularization and application of the brush plating process, it has been expanded from the maintenance of the mechanical equipment to the product manufacturing process and has become one of the important technological means for prolonging the production and maintenance cycle of the major and key products. In view of the special requirements of hydropower products such as heavy parts, large area and harsh working conditions, the coating should require anti-corrosion property in addition to the required anti-corrosion property in the rotating parts of the machinery. In particular, the parts of the hydraulic parts are both anti-corrosion Wear is a special requirement of hydropower products. In the past, mistakenly believe that: hydraulic sealing parts are often in oil film protection, will not corrode, most do not use anti-corrosion measures. However, during the actual operating conditions, especially during downtime, will lose the oil film protection, then the substrate will be subject to varying degrees of corrosion,
