Abstract

Bu çalışmanın amacı, X6Cr17 ferritik paslanmaz çeliklerin yüzey özelliklerini, termal sprey yöntemlerden biri olan plazma sprey yöntemini kullanarak 0-100 um, 100-200 um ve 200-300 um kalınlığında Al2O3-Ti02 tozları ile kaplayarak geliştirmektir. Kaplama işleminden sonra numunelerin aşınma direnci araştırılmıştır. Aşınma Testleri, ASTM G133 standardına göre disk üzerinde pim yöntemi ile gerçekleştirilmiştir. Sonuçların incelenmesinden sonra, A3 numunesinin en yüksek aşınma direncine sahip olduğu gözlenmiştir.

Wear Resistances of X6Cr17 Ferritic Stainless Steel Surfaces Coated with Al2O3 Powders Using Thermal Spray Method

Abstract

The aim of this study was to improve the surface properties of the X6Cr17 ferritic stainless steels by coating with the Al2O3-TiO2 powders in the thickness of 0-100μm, 100-200μm and 200-300μm by using the plasma spray method, one of thermal spray methods. Wear resistance of the samples was investigated after the coating process. The tests were carried out by pin-on-disc method according to ASTM G133 standard. After examination of the results, it was observed highest abrasion resistance of A3 sample. It was concluded that the abrasion resistance in the high hardness sample does not mean that it will be good due to the high hardness.
