摘要：

A borosilicate glass coating for SiC pre-coated carbon/carbon composites (SiC-C/C) was prepared by pulse arc discharge deposition (PADD). Its thickness, compactness and oxidation resistance increases with the rise of deposition voltage from 300 to 400 V. The glass coating prepared at a deposition voltage of 400 V can protect C/C composites from oxidation in air at 1823 K for 156 h with a weight loss of 2.13%. The failure mechanism of the borosilicate glass/SiC coatings was investigated. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
