In view of more stringent environmental protection requirements which, amongst other targets, demand great weight reductions in the automotive field, there are increasing endeavours to substitute magnesium for materials with higher mass densities. One standardised possibility of counteracting magnesium’s high affinity for oxygen is to use thermally sprayed corrosion protection coatings. However, traditional thermal coating procedures have various process-induced restrictions. The procedure for transplanting thermally sprayed coatings offers new solution approaches here: Some of the restrictions of traditional coating procedures can be resolved because of the altered process chain. In this paper, the effectiveness of transplanted thermally sprayed corrosion protection coatings is investigated and compared with conventional coatings and their utilisation potentials are discussed in relation to industrial applications.
