| Abstract: |
| Objective To study the mould resistance of protective layers on high-strength alloy structural steel and high-strength aluminum alloy. Methods Different protective layers were prepared on high-strength alloy structural steel and high-strength aluminum alloy. Laboratory mould tests were carried out according to GJB 150.10A-2009 to evaluate the mould growth level on the protective layers. Results The mold levels of lubricant coating and anode oxidation layer on high-strength alloy structural steel and high-strength aluminum alloy were in the range of grade 0 ~ 1; the mold level of gun oil coating, paint coating, zinc layer or zinc nickel alloy layer moldy grade were in the range of grade 2~3. Conclusion For high-strength alloy structural steel substrate, lubricant coating had good mould resistance, while galvanized layer or zinc alloy layer, paint coating and gun oil coating had poor mould resistance. For high-strength aluminum alloy substrate, anode oxidation layer had good mould resistance, while gun oil coating and paint coating had poor mould resistance. |
