Abstract In the present study, layers consisting of 40% Stellite-6 and 60% WC were deposited on Ti-6Al-3Mo-2Sn-2Zr-2Nb-1.5Cr-0.1Si (TC21) alloy by means direct energy deposition (DED) technology aiming to improve microstructure microhardness. Five powder feeding rates ranging from 20 100 ɡ min −1 applied using CW fiber-coupled diode laser with 4 kW output power. The analyzed via scanning electr...

In this work, Cladding was done on SS316L alloy through the CMT process using Stellite-6 filler wire. 31 experiments were at different welding conditions as per CCD matrix. The cladding specimens characterized by macro and micro-study, Vickers microhardness evaluation corrosion resistance analysis. An optical microscope, SEM-EDAX, XRD used to predict structural characterizations, presence distr...

(HIPing), can improve the tribo-mechanical properties of cobalt-based alloys. The alloy selected for this investigation had a nominal wt.% composition of Co-30Cr-14W-1C, which is similar to the composition of the commercially available Stellite®4 alloy. The Hot Isostatic Pressed (HIPed) alloy had a much finer microstructure than the cast alloy, which showed a typical hypoeutectic dendritic micr...

Bu çalışmada Stellite 21 süper alaşımı, uygun kompozisyonda hazırlanarak homojen karıştırma sonrası elde edilen toz karışım kullanılmak suretiyle, elektrik akımı destekli sinterleme yöntemi ile üretilmiştir. Daha sonra numunelerin sertlik, mukavemet ve yüksek sıcaklık özellikleri gibi özelliklerini geliştirmek için ısıl işlem uygulanmıştır. Üretilen malzemenin; mikroyapı görüntüleri taramalı el...
