Abstract
The present invention provides methods for treating ceramic materials, including oxide ceramic materials such as zirconia, with a treatment agent comprising a metallic material, such as titanium, by contacting a surface of the ceramic material with the treatment agent and heating the assembly to a temperature at which the ceramic material incorporates a portion of the metallic material by diffusion. The treated ceramic material is uniformly darkened and exhibits improved structural and physical properties.
