The invention relates to a method for joining ceramic composite parts comprising at least one ceramic material and at least one superhard material to at least one other part, the method comprising treatment of a join surface or surfaces of the ceramic composite part; and disposition onto the treated surface or surfaces, or portions thereof, of a material capable of bonding to the ceramic composite part as well as to the at least one other part upon the application of sufficient heat. The invention extends to articles comprising a ceramic composite part comprising ceramic material and at least one superhard material, bonded to at least one other part, the article including at least one layer selected from an attachment layer, a brazeable layer, and an oxidation resistant (braze compatible) layer or combinations thereof included at an interface between the ceramic composite part and the other part.
