ABSTRACT:
A method for the chemical-mechanical polishing of titanium carbide surfaces to a high degree of perfection is described. The titanium carbide surfaces are continuously wetted with a water slurry containing a soft abrasive material. The continuously wiping of the titanium carbide surface is accomplished with a firm surface using pressure while maintaining a relative movement between the titanium carbide surface and the firm surface to remove the water reacted titanium carbide product from the high points of the titanium carbide surface. This method is continued until a high degree of perfection of the surface is accomplished. The slurry is typically composed of colloidal silicon dioxide dispersed in water. The titanium carbide surface can also include an aluminum oxide component. Where aluminum oxide is present it is preferred to have about 60 to 80% aluminum oxide and 40 to 20% titanium carbide by weight in the surface structure.
