摘要：
In this study, AISI 304 austenitic stainless steel was coated with Ni3Al intermetallic alloy. Coating layers were formed at 110, 120 and 130 A currents values by plasma transfer arc (PTA) process with using argon gas for both plasma and protective. Analyses of microhardness, SEM, EDX and XRD were carried out in order to examine surface and interface characteristics of the coating layers. From the results, it was found that the primer Ni3Al phase and secondary NiAl phase existed in the Ni3Al alloy coating obtained by PTA process at 110 A current. From the results, it was seen that increased current values caused to the cracks in the coating layer and also affected the coating layer and interface microstructure.
