Bu çaly?mada, AISI 304 ostenitik paslanmaz çelik yüzeyine FeTi +Stellite 6 ala?ymy Tungsten Inert Gas (TIG) kaynak yöntemi kullanylarak ala?ymlandyrylmy?tyr. Kaplama tabakasy; optik mikroskop (OM), taramaly elektron mikroskobu (SEM), X-y?yn difraktogramy (XRD) ve X y?yny enerji da?ylym spektrometresinden (EDS) faydalanylarak incelenmi?tir. Ayryca numunelerin sertlik da?ylymlary mikro ve makro sertlik ölçümleri ile de?erlendirildi. Optik mikroskop ve mikroyapy incelemeleri neticesinde, kaplama tabakasy ile alt tabakanyn birbirlerine metalurjik olarak ba?landy?y, numunelerde, FeTi tozu ilavesine ba?ly olarak sertlik de?erlerinin artty?y ve tane synyrlarynda ince taneli dentritik yapylaryn meydana geldi?i tespit edilmi?tir.

In this study, FeTi with Stellite 6 alloy on the 304 austenitic stainless steel surface by using Tungsten Inert Gas (TIG) processing. Alloyed layer and interface were examined with optical microscope (OM), scanning electron microscope (SEM), and X-Ray diffraction (XRD) and energy dispersive spectograph. Macro and microhardness values of samples were measured. OM and SEM observations have been shown that the obtained coating had a smooth and uniform surface, as well as a metallurgical combination with the AISI 304 stainless steel substrate without cracks and pores at the interface. As a result of experimental study; hardness values of samples increased and the grain boundaries were occurred dendritic structures has been determined
