Elektrik Ark Püskürtme TEkniği ile Üretilmiş Ssrmet Kaplamaların Abrazif Aşınma Performanslarının İncelenmesi

FeCrCMn alaşım kaplamalar şiddetli abrazif aşınmaya maruz kalan parçalara abrazif aşınma direnci kazandırmak için yaygın olarak uygulanmaktadır. Elektrik ark püskürtme kaplama tekniği termal püskürtme yöntemleri arasında en uygun uygulama ve maliyet avantajlı yöntemdir. Bu çalışmada elektrik ark püskürtme kaplama tekniği ile üretilmiş FeCrCMn kaplamalar, optik mikroskop, SEM incelemesi yapılmış olup mikrosertlikleri ölçülmüştür. Fazların tayini için EDS ve XRD analizleri gerçekleştirilmiştir. ASTM G65-04’e gore 13 Cr’lu çelik kaplama ile aşınma performansları karşılaştırılmıştır.

The Investigation of the Abrasive Wear Performance of Cermet Coatings Produdec by Electric Are Spraying Technique

FeCrCMn alloys coatings are widely used to components to resist abrasive wear when they exposure in severe abrasive environment. Electrical arc spraying is one of the thermal spray coating technique has low cost and easy application. In this study, FeCrCMn coating and steel wire coating (13 Cr) produced by electrical arc spraying with optimated parameters are investigated by optical microscopy, SEM. Microhardness measurement of coatings were carried out and analyzed by EDS and XRD for determine phases. Then they tested for abrasive wear according to ASTM G65-04 norm and compared abrasive wear performance of these coating.© Afyon Kocatepe Üniversitesi
