Bu çalışma kapsamında, düşük kabonlu çelik üzerine NiCr bağlayıcı tabaka uygulandıktan sonra
alevle tel püskürtme (WSF) ve yüksek hızlı oksijen yakıt (HVOF) gibi iki farklı termal püskürtme işlemi ile
östenitik paslanmaz çelik kaplamalar oluşturulduktan sonra optik mikroskop ve mikrosertlik ölçümleri ile yüzey
özellikleri ve performansları karşılaştırılmıştır. 316L paslanmaz çelik kaplamaların korozyon direnci
potansiyodinamik polarizasyon tarama (PDS) teknik ile belirlenmiştir. Aşınma deneyleri ise salınım hareketli
aşınma test cihazında karşı malzeme olarak Al2O3 bilye kullanılarak kuru ortamda gerçekleştirilmiştir. HVOF
püskürtme ile elde edilen 316 L paslanmaz çelik kaplama, alevle te püskürtme yöntemi ile elde edilen 316 L
paslanmaz çelik kaplamaya göre daha yüksek sertlik ve aşınma direnci sergilemiştir. Ancak, korozyona karşı
alevle tel püskürtme yöntemi ile elde edilen 316 L paslanmaz çelik kaplamanın daha koruyucu olabileceği
görülmüştür.

A Comparative Study of Thermal Sprayed AISI 316L Stainless Steel Coatings
In this study, austenitic stainless steel (316L) coatings were formed using both Wire Flame Spray Forming (WSF) and High Velocity Oxy Fuel (HVOF) deposition processes after a NiCr bond layer was deposited on low carbon steel substrate. The coatings were characterized by light optical microscope (LOM) and microhardness measurements. Corrosion resistance of 316L austenitic stainless steel coatings applied onto low carbon steel via WSF and HVOF spray processes was analyzed by using the potentiodynamic polarization scanning (PDS) technique. The wear behaviour of the coatings against Al2O3 ball was investigated with a reciprocating tester under dry friction conditions. It was found that the HVOF sprayed coating showed higher hardness and better wear resistance than the WSF coating. However, the overall corrosion resistance of the HVOF deposited coating was inferior to that of the WSF coating.
