Fe-Cr-C, Fe-Cr-C/FeNb
ve Fe-Cr-C/TiC kaplamalarına M₇C₃ ve M(Nb,Ti)C karbürlerinin
etkisini incelemek için gaz tungsten ark tekniği kullanılarak orta karbonlu çelik
altlık yüzeyinde hazırlandı ve elde edilen kompozit kaplamaların mikroyapı ve
özellikleri optik mikroskop ve taramalı elektron mikroskobu kullanılarak
incelendi. Fe-Cr-C kaplamalarında mikroyapıda hegzagonal ve sivri uçlu M₇C₃
karbürleri oluşurken, FeNb ve TiC ilaveli kaplama tabakalarında g-(Fe,Cr) ötektik matriste birincil M₇C₃
karbürleriyle birlikte üçgen görünümlü NbC ve dörtgen görünümlü TiC taneleriyle
katılaşma meydana geldiği belirlendi.

Anahtar Kelimeler
