Title: METHOD TO OBTAIN A REFRACTORY COMPOSITE MATERIAL BASED ON CARBIDE
Abstract:
The present invention relates to a method to obtain a refractory carbide-based composite material, in particular as an article of a predetermined shape. According to the invention the method includes the following steps: molding of a porous blank from a mixture of powders of at least one carbide-forming metal and/or non-metal and at least one carbide, the amount of carbide component in the mixture of powders not exceeding 90 %, heat treating the obtained porous blank in a hydrocarbonous atmosphere containing one or more hydrocarbons until the increase in its mass reaches 2-42 %, thereby obtaining a semi-product, and heating the obtained semi-product in a non-oxidizing medium at a temperature of 1000-2000 °C.
