Bu çalışmanın amacı; farklı oranlarda Co-Cr esaslı
WC takviyeli tozların TIG kaynak yöntemi kullanılarak St52 çeliğinin yüzeyine
ergitilmesi yöntemi ile kaplamaları yapılmasıdır. Farklı özellikteki çelik alt
tabakaları üzerine WC-Co-Cr toz karışımları belirlenen oranlarda önceden yerleştirildi
ve TIG kaynak işlemi ile kaplama işlemleri yapıldı. Farklı özellikteki kaplama
tabakaları çelik alt tabakaya yoğun ve neredeyse hiç gözenek olmadan metalürjik
bir bağlanma gösterdi.  Kaplamaların
mikroyapı ve faz analizi için, taramalı elektron mikroskobu (SEM), EDS ve X-Ray
incelemeleri yapıldı. X-ışın kırınımı incelemesi sonucu, kaplamalarda WC’ lerce
zengin düzensiz dağılımlı ötektik yapılarla birlikte birincil dentritik
fazlarında olduğu ayrıca WC-Co-Cr kaplamaları WC ve W2C ile CrC ve Cr3C2 karbürleri
ile Kobalt, Nikel, Karbonun düzensiz dağılım gösteren fazlarından oluşmuştur.
