EFFECT OF RARE EARTH CONVERSION COATING ON SCC RESISTANCE OF LC4 ALUMINIUM ALLOY
铝合金稀土转化膜处理对LC4合金耐SCC性能的影响

The effect of rare earth conversion coatings P5 and SRE on SCC behavior of LC4 aluminium alloy in 3.5% NaCl has been studied by SSRT and other methods. The stress corrosion cracking of LC4 alloy was inhibited to some extent after P5 or SRE treatment. Some inhibition effect on SCC was shown in SRE treatment solution.
