Heat-resistant slip coatings of the ZrB2–MoSi2–SiC system on CCCM were examined for protection of aerospace technology elements from oxidation. The following compositions (mass%) were studied as coating materials: 55 ZrB2 + 25 MoSi2 + 20 SiC (ZSM25), 50 ZrB2 + 30 MoSi2 + 20 SiC (ZSM30), and 45 ZrB2 + 35 MoSi2 + 20 SiC (ZSM35). Heat-treatment modes were elaborated for the coatings. The optimal method for producing heat-resistant coatings was selected. The ZSM25 coating was found to satisfy the heat-resistance assessment tests conditions in a Multiplaz 2500-m plasmatron for 20 sec at an angle of 45°, presumably by forming a highly viscous ZrSiO4 film.

航空航天用碳-碳复合材料上的ZrB 2 -MoSi 2 -SiC耐热涂层
检查了CCCM上ZrB 2 -MoSi 2 -SiC系统的耐热滑爽涂料,以保护航空航天技术元素免受氧化。研究了以下组成(质量%)作为涂层材料:55 ZrB 2 + 25 MoSi 2 + 20 SiC(ZSM25),50 ZrB 2 + 30 MoSi 2 + 20 SiC(ZSM30)和45 ZrB 2 + 35 MoSi 2+ 20 SiC(ZSM35)。阐述了涂层的热处理方式。选择了生产耐热涂层的最佳方法。发现ZSM25涂层在Multiplaz 2500-m等离子加速器中以45°角满足20秒的耐热性评估测试条件,大概是通过形成高粘性的ZrSiO 4膜来实现的。
