| Abstract: |
| 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. |
