ABSTRACT:
A body of monolithic or composite partially stabilized zirconia is subjected to intense surface heating which raises the temperature of the exposed surface to 1100.degree. C.-1600.degree. C. without heating the interior of the body above 600.degree. C.-800.degree. C., and then the body is cooled. The heat treated body shows increased wear resistance and surface hardness as compared with an untreated body.
