A method of Protecting an article from Carbonaceous oxidation and erosion at elevated temperature

摘要

Method for Protecting an article Carbonaceous oxidation and erosion at elevated temperatures.It includes the following Operations: First, a mixture is prepared into particles formed by 20 to 70% by weight of Mullite, by 5 to 14% by weight of silica, from 5 to 70% by weight of a metal Carbide selected from Silicon carbide and BORON CARBIDE, and a 5 to 14% in pes Or a binding material containing SiliconWhile the percentage of the total weight of the dry ingredients; Second, the Article applies to surfaces of Carbonaceous particles prepared in the mixture; and finally, the mixture is heated to a temperature such particles, to form a Refractory Lining Ceramic, Glass and rigid.
