Composite refractory protective coatings for carbon-graphite materials

Production examples are considered for improving the refractoriness of structural graphites and carbon-ceramic composite materials and constructions of them created on the basis of surface composite heat-resistant coatings based on molybdenum silicide and silicon carbide. The temperature limits for coating preparation and their operating capacity are determined. The structure of composite refractory coatings is studied by optical methods. The optimum limit for pyrolytic coatings is established.
