Abstract

ZrB₂-SiC coatings were prepared on the SiC coated specimens by pack cementation method at 1900 °C for 2 h. The phase, microstructure, anti-oxidation and thermal shock resistance properties of these coatings were investigated. It was found that ZrB₂-SiC coatings improved anti-oxidation and thermal shock resistance. ZS50 coating endured 15 thermal shock cycles between 1500 °C and room temperature with 20.2% weight loss, which was attributed to the dense glass phase formed after oxidation.
