A Comparative Study of SiAlON Ceramics
Mallik, Awadesh Kumar; Açıkbaş, Nurcan Çalış; Kara, Ferhat; Mandal, Hasan; Basu, Debabrata (Elsevier, 2012)Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% b-Si3N4 was used from refractory grade powders (B1) and another purer 98% a-Si3N4 (50A) powder was used to prepare the SiAlON samples. ... -
Influence of SiC addition on tribological properties of SiAlON
Mallik, Awadesh Kumar; Reddy, Kolan Madhav; Çalış Açıkbaş, Nurcan; Kara, Ferhat; Mandal, Hasan; Basu, Debabrata; Basu, Bikramjit (Elsevier, 2011)The tribological properties of gas pressure sintered SiAlON and its composite with 18 wt% silicon carbide (SiC) against two different mating materials, i.e., alumina and SiAlON are evaluated. SiAlON and SiAlON–18%SiC ... -
Processing of solid state sintered alpha-SiC ceramics with carbon-black addition
Çelik, Ali; Kara, Alpagut; Turan, Servet; Kara, Ferhat (IOP Publishing, 2019)The efficient removal of surface silica layer from SiC particles by the addition of carbon is required for solid state sintering (SSS) of SiC ceramics. While wax-based organics are generally utilized as carbon source in ... -
Wear Behavior of Solid SiAlON Milling Tools During High Speed Milling of Inconel 718
Çelik, Ali; Alağaç, Melike Sert; Turan, Servet; Kara, Alpagut; Kara, Ferhat (Elsevier, 2017)Machining of Inconel 718 is a challenging process because of high hot strength and hardness, high re-activity with the tool materials and low thermal conductivity of Inconel 718 alloy. Although SiAlONceramics in the form ...
