| Abstract: |
Self-fluxing alloys are used as thermal spray coatings against strong tribological and corrosive stresses. In order to obtain a completely dense and strongly adherent coating, they are subsequently remelted. In particular, nickel- and cobalt-based alloys have been used so far. The extension of the alloying approach to complex alloys without a determining main alloying element promises a significant increase in the coating properties and thus an increase in component service life. The current work focuses on the alloy development of the high entropy alloy CrFeNiBSiC using an electric arc furnace, the subsequent powder production as well as the coating production by thermal spraying. The properties of the coatings are charaterized and evaluated. The results confirm the potential of the new development approach.
