Effect of trivalent chromium process on fatigue lifetime of 2024-T3 aluminium alloy

The effect of a new alternative trivalent chromium conversion process on fatigue lifetime of a 2024-T3 aluminium alloy was investigated. The decrease in fatigue-life induced by coating process was related to the dissolution of coarse intermetallic particles during the deoxidation pre-treatment prece...

Zusammenfassung:The effect of a new alternative trivalent chromium conversion process on fatigue lifetime of a 2024-T3 aluminium alloy was investigated. The decrease in fatigue-life induced by coating process was related to the dissolution of coarse intermetallic particles during the deoxidation pre-treatment preceding the conversion layer growth.
