Influence of Si addition on the microstructure, mechanical and lead-bismuth eutectic corrosion properties of an amorphous AlCrFeMoTiSix high-entropy alloy coating
Source abstract
Abstract
The effect of the Si addition content ranging from 3.3 to 9.1 at.% on the microstructure, mechanical properties and LBE corrosion behaviour of AlCrFeMoTiSi x HEA coatings was investigated. The coatings still maintained an amorphous structure, and their mechanical properties were improved. The Si addition greatly contributed to the enhancement of the LBE corrosion resistance of the coatings, which could be attributed to the formation of a more continuous and protective Cr 2O 3 and Al 2O 3 layer. However, the improved efficiency was related to the Si addition content, with an oxidation process model put forwards to well explain this phenomenon.
