A method of impregnating the surface of a ceramic disk for use in a faucet valve to fill the pores of the ceramic plate and reduce the coefficient of friction between cooperating plates which control the fluid flow through the faucet valve. The plates are impregnated by subjecting the plates to a carburizing gas under heat over an extended period of time. The process causes a carbon matrix to fill the pores of the ceramic plate. Thereafter, the plates are lapped and polished to remove any excess deposits from the plate surface. The process forms a pair of cooperating plates for use in a faucet valve which eliminate sticking or lock-up of the valve assembly. |
