BONDING BETWEEN METALS AND MULTICOMPONENT PHOSPHATE BASED CERAMIC-GLASS - APPLICATION TO THE ENAMELLING OF NICKEL AND TITANIUM

Phosphates based ceramics and glasses present many interest in very va rious applications fields like industry or medecine for coating metal substrate. The physical analysis exhibit a bonding by formation of ort hophosphate with nickel substrate. This is a classical joining between metal and glass by the way of metal oxyde. But with titanium, these a nalysis exhibit the formation of a solid solution of Ti O P system at the surface of metal which explains the creation of new kind bonding b etween the metal substrate and the metaphosphate glass.
