Wear behavior of solid SiAlON milling tools during high speed milling of Inconel 718
(Elsevier Science Sa, 2017)Machining of Inconel 718 is a challenging process because of high hot strength and hardness, high reactivity with the tool materials and low thermal conductivity of Inconel 718 alloy. Although SiAION ceramics in the form ... -
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
(Elsevier Sci LTD, 2009)alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ... -
Wear Characteristics of Traditional Manganese Phosphate and Composite hBN Coatings
(Taylor & Francis Inc, 2013)In this study, the tribological properties of traditional manganese phosphate coatings and composite hBN coatings composed of nano-hexagonal boron nitride (hBN) in layered manganese phosphate crystals on AISI 1040 steel ... -
Wear on SiAlON ceramic tools in drilling of aerospace grade CFRP composites
(Elsevier Science Sa, 2015)Carbon fiber reinforced polymer (CFRP) composites are difficult to cut materials due to their anisotropic structure and extremely abrasive nature of the carbon fibers. The tool materials used for drilling of CFRP composites ... -
Wear properties of alpha- and alpha/beta-SiAlON ceramics obtained by gas pressure sintering and spark plasma sintering
(Elsevier Sci LTD, 2011)In this study, alpha- and alpha/beta-SiAlON materials, doped with Y(2)O(3) and Nd(2)O(3), were sintered using two different sintering processes: spark plasma sintering (SPS) and gas pressure sintering (GPS). The wear and ... -
Yerli Borik Asitten Kalıntı Karbon İçermeyen Bor Karbür Sentezi
(2018)Bu çalışmada, yerli borik asit ve teknik kalite mannitol kullanılarak borik asidin esterifikasyonuyla sentezlenen jel öncü malzemeler üzerinden kalıntı karbon içermeyen bor karbür tozlarının üretimi karbotermik indirgeme ... -
Young's modulus measurements of magnesia-spinel composites using load-deflection curves, sonic modulus, strain gauges and Rayleigh waves
(Elsevier Sci LTD, 2003)The extent of interlinking of the microcracking and a decrease in strength and modulus values were determined to be a function of both spinel particle size and volume fraction to allow calculation of thermal shock parameter, ... -
Zircon-free frits suitable for single fast-firing opaque wall tile glazes and their industrial productions
(Elsevier Sci LTD, 2009)Wall tile glazes with a smooth surface texture, high glossiness, and whiteness are usually based on zirconium containing frits. However, these frits are quite expensive and therefore, there have recently been certain ... -
? › ß reverse phase transformation in silicon carbide in silicon nitride-particulate-reinforced-silicon carbide composites
(American Ceramic Society, 1996)The ? › ß reverse transformation in SiC is observed in Si3N4-particulate-reinforced-SiC composites made from as-received ?-SiC and ?-Si3N4 powders. However, the transformation does not occur to any great extent in composites ... -
?/ß SiAlON based composites incorporated with MoSi2 for electrical applications
(2010)Electrically conductive ?-ß SiAlON composites containing 30 vol. % MoSi2 was prepared by gas pressure sintering (GPS). The effect of sintering atmosphere on phase formation, grain growth, mechanical and electrical properties ...
