Electro Spark Deposition Of Hfnbtatizr High Entropy Alloy Processed In Solid State And Experimental Adhesive Testing

HfNbTaTiZr high entropy alloy was deposited on a stainless steel surface by electro spark deposition (ESD) technique and investigated. The alloy was previously produced by solid state processing method and characterized, where promising results were obtained. The alloyed powder was consolidated by using spark plasma sintering technique. Electrodes were manufactured from the bulk material, with an optimized shape for better performances for the ESD process.For the pull off test a designed and manufactured device was utilized and the results are presented. The microstructure analysis present that HfNbTaTiZr high entropy alloy coating was obtained, fissures and cracks not being present.
