中文摘要:
      针对空客生产的A320机型合金钢零件镀硬铬层高耐腐蚀性的要求,研究了一种高耐蚀性镀硬铬工艺,所获得的镀铬层硬度为750~980HV,并且通过了750h的盐雾试验,满足空客技术要求。研究还发现,特殊的电镀硬铬工艺,尤其是镀铬后的HA 油除氢、磨削等是提高硬铬镀层耐腐蚀性能的关键。该工艺目前已在工厂的批量生产中获得应用。
英文摘要:
      Based on the requirement of high anti-corrosion of Airbus A320 alloy steel parts hard chrome plating, the hard chromium plating process for low alloy steels was investigated. This achieved chromium layer had high hardness(750~980HV), could pass 750 h salt spray test and meet the airbus technical requirement. It was also found that hydrogen relief with HA oil and grinding procedures were the key points to improve its corrosion resistance. This high anti-corrosion hard chromium plating process has already been applied on serial production of Airbus A320 model.
