ABSTRACT:
Novel ceramic or metal-ceramic articles having an oxidized surface are produced by a tribochemical method. The oxidized surface is produced by initially wear scarring, under high vacuum, opposed, articulating ceramic or metal-ceramic surfaces and, thereafter, continuing the wear scarring in the presence of oxygen or air at less than atmospheric pressure. A method of welding ceramic or metal-ceramic articles is also disclosed.
