HEAfilmonMg Fabrication & characterisation of protective HEA films on Mg substrate by mechanical alloying, cold spraying & post-surface laser annealing processing

Summary

Protective high entropy alloys (HEA) thin films/coatings on Mg substrate will be produced by mechanical alloying (MA), cold spraying (CS) and post-surface laser annealing (SLA) process. By using variable but controlled MA process and CS coating parameters (HEA feedstock powder & HEA MAed powder characteristics, CS technology geometric parameters, CS deposition parameters), variations in the micro-structure and property in HEA coatings will be attained. Microstructural characterization of HEA feedstock powders, MAed powders, CS coatings and CS+post-SLA coatings will be carried out by SEM, TEM, XRD, porosity measurements. Wear, oxidation, corrosion tests, hardness and elongation measurements will be made to determine chemical and mechanical properties of coatings. With this way relationships among deposition parameters-microstructure-properties will be determined in addition to the feasibility study of producing protective (wear and oxidation resistant) HEA coatings on Mg-parts by combined MA+CS & post- SLA process.
