Abstract
The present invention provides a method for treating a ceramic body to provide a wettable surface on the ceramic body. According to the present invention, a ceramic body is immersed in an alkaline hydroxide solution. The ceramic body is connected to form the anode and a suitable metal is connected to form the cathode of an electrolytic cell. A difference in electrical potential is imposed across the electrolytic cell which is sufficient to remove portions of the ceramic body to provide a pitted surface on the ceramic body which is wettable.

A method for treating a ceramic body to provide a wettable surface on the ceramic body, comprising:
- immersing the ceramic body in an alkaline hydroxide solution bath;
- connecting the ceramic body to form an anode of an electrolytic cell;
- connecting a stainless steel object to form a cathode of the electrolytic cell;
- imposing a difference in electrical potential across the electrolytic cell sufficient to remove portions of the ceramic body to provide a pitted surface on the ceramic body which is wettable;
- and
- removing the ceramic body from the alkaline hydroxide solution bath.
