Role of TiC and WC Addition on the Mechanism and Kinetics of Isothermal Oxidation and High-Temperature Stability of ZrB2–SiC Composites
This study investigates the influence of separate and combined addition of 5 vol.% TiC and/or WC on the isothermal oxidation behaviour of ZrB2–20 vol.% SiC composites consolidated by a spark plasma sintering route. The oxidation performance of the composites was evaluated in the temperature range of 1500–1600 °C in air for up to 4 h. Following oxidation, the samples were subjected to a detailed characterization of the microstructure, micro-composition, phase aggregate, and oxide scale growth kinetics. The thermodynamic feasibility of probable reactions and the phase stability of Zr–B–O, Zr–Si–O, Ti–B–O, Ti–C–O, Ti–W–O, and W–C–O systems were examined by dedicated software. While addition of TiC or WC was found to result in protective oxide scale formation, the highest oxidation resistance in terms of reduced mass gain and oxide layer thickness was offered by ZrB2–20SiC–2.5TiC–2.5WC (vol.%) composite at 1500–1600 °C in air.
期刊介绍：
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
