Purpose and goal
The overall aim of the project is to establish how high entropy alloys can be transferred into fabrication for potential industrial application. This has been done by demonstrating for one high entropy alloy how it can developed with aid of theory/modelling to powder fabrication and further to laser-assisted coating including evaluation of selected performance criteria. The project has hence fullfiled its goals.
Results and expected effects
In this project, we have shown how a high entropy alloy can be developed and fabricated into coatings with support from theoery/modelling using the way via metal powder. We have thus shown the potential for a new material concept and we have also illustrated in practice how rapid materials development could be realised. Making coatings as first option is here an interesting way as the critical iisues are coating function and quality rahter than sturctural loading capacity. The powder way also opens up ways for component manufacture using diffferent technologies.
Approach and implementation
The work has been done by means of joint efforts at Chalmers, Swerea KIMAB and Höganäs AB, Chalmers (Materials and Manufacturing Technology) has been responsible for materials design and characterisation. Höganäs has fabricated powder and lasercoated specimens as well as carried out wear testing. Swerea KIMAB has supported with modelling. The necessary combination of experimental and theoretical resources/knowledge has hence been created and the chain from idea to demonstration has been secured.
