Study of Synthesis and Evaluation of Heat-Resistant Coatings Based on Silicon–Boron Carbide–Zirconium Boride–Aluminum Oxide Composite
- 11 Downloads
The effect of nanosized fibers of aluminum oxide on the properties of protective coatings based on the silicon–boron carbide–zirconium boride composite is investigated. The coatings applied on different substrates (graphite and ceramics) are compared and the effect of the thermal treatment conditions on the formed coatings is examined. It is demonstrated that the introduced additives do not weaken the coating’s thermal resistance and allow reducing the cost of the coating, darkening the color, and protecting it from erosion.
