EIS and corrosion behaviour of plasma sprayed layers of Al and AlCr6Fe2 on AZ91

EIS and corrosion behaviour of plasma sprayed layers of Al and AlCr6Fe2 on AZ91

This work presents the preparation of coatings of aluminium and AlCr6Fe2 alloy on magnesium alloy AZ91 with metallurgical bonding. Coatings were prepared by plasma spraying system WSP®-H 500. This metallurgical bond (sub-layer) is formed by an eutectic structure consisting of the intermetallic phase...
