“…ZrB 2 -30 vol.% SiC-20 vol.% MoSi 2 ceramic (ZSM) and ZrB 2 -30 vol.% SiC ceramic (ZS) were successfully prepared via SPS sintering at 1900 0 C. The density was calculated, the hardness, three-point bending strength at room temperature and high temperature were measured and shown in Table 1. The density of ZSM and ZS were both higher than 5 g/cm 3 , close to their theoretical densities. The hardness of ZSM and ZS were 17.2 and 19.6 GPa, separately.…”

“…In recent years, ZrB 2 -SiC ceramic have become one of the most attractive candidate materials for the thermal protection system of the next generation hypersonic vehicles due to its high melting points, high strength, high thermal conductivity and relatively low density [1,2,3,4]. During supersonic flight and re-entry process, ZrB 2 -SiC ceramic will serve in extremely harsh oxidative environment at high temperature.…”

Abstract. ZrB 2 -SiC-MoSi 2 ceramic (ZSM) was successfully prepared by SPS sintering process. The micro-structure and mechanical property were characterized, the oxidation behavior of ZSM was mainly studied at 1500 0 C in air. Compared to ZrB 2 -SiC ceramic (ZS), the mechanical property of ZSM was improved significantly. MoB phase increasing the mechanical and chemical bonding force between different phases was formed in ZSM during SPS sintering. After 10 h oxidation at 1500 0 C in air, oxide layer thickness of ZSM was thinner than ZS, oxidation resistance of ZSM was better than ZS.

“…Although sphene and HAp powders have similar size distribution, however, the shape of powders may be a little different. Powder shape will affect powder flowability and further affect the coating density (Bartuli et al 2002). In addition, the plasma spraying technique produced sphene coating with denser microstructure than the sol-gel technique.…”

Novel Ca-Si-Ti-based sphene (CaTiSiO 5 ) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study was to prepare sphene coating on titanium alloy (Ti-6Al-4V) for orthopaedic applications using the plasma spray method. The phase composition, surface and interface microstructure, coating thickness, surface roughness and bonding strength of the plasma-sprayed sphene coating were analysed using X-ray diffraction, scanning electron microscopy, atomic force microscopy and the standard mechanical testing of the American Society for Testing and Materials, respectively. The results indicated that sphene coating was obtained with a uniform and dense microstructure at the interface of the Ti-6Al-4V surface and the thickness and surface roughness of the coating were approximately 150 and 10 mm, respectively. Plasma-sprayed sphene coating on Ti-6Al-4V possessed a significantly improved bonding strength and chemical stability compared with plasma-sprayed hydroxyapatite (HAp) coating. Plasma-sprayed sphene coating supported human osteoblast-like cell (HOB) attachment and significantly enhanced HOB proliferation and differentiation compared with plasma-sprayed HAp coating and uncoated Ti-6Al-4V. Taken together, plasma-sprayed sphene coating on Ti-6Al-4V possessed excellent bonding strength, chemical stability and cellular bioactivity, indicating its potential application for orthopaedic implants.

“…Thus, one strategy employs eutectic mixtures whose melting point is lower than the oxidation temperature of SiC [14,15]. Another sealing mechanism resides in encapsulating the sealing agent (core-shell) by metal compounds, to produce a selective oxidation of the metal elements which prevents the sealing agent from further oxidation [10,16].…”

In order to obtain thermal barrier coatings by Suspension Plasma Spraying (SPS) process with potential new self-healing ability multicomponent submicronic Y-TZP/Al2O3/SiC suspensions were prepared. For this purpose, concentrated aqueous suspensions of individual components as well as the multicomponent mixture were studied and characterised in terms of colloidal stability and rheological behaviour to determine the best conditions for processing and preparation of the coatings. In the study, different dispersant contents and sonication times were tested. Subsequently, low concentrated suspensions were prepared to obtain preliminary thermal barrier coatings with the optimised feedstock. Thus, ceramic coatings were deposited by SPS and then characterised in order to assess the microstructure and phase distribution, in particular, the degree of preservation of the sealing agent, SiC, in the final coating as a previous indicator of its self-healing ability.
