Abstract
Wire-arc-sprayed coatings are widely used to protect industrial parts mainly from wear and erosion. The present work combines experimental measurements performed by instrumented indentation and their modeling in order to determine the elastic–plastic behavior of a wire-arc sprayed FeCrNiBSi–(W–Ti)C using Metco 8297 cored wire as feedstock material. The coating was sprayed onto low carbon steel (C35) substrate after cleaning and grit blasting. The elastic–plastic behavior law optimized from instrumented indentation tests allowed calculating the coating adhesion. The effect of the displacement velocity of the tensile test on the fracture resistance was also investigated.
