Abstract

A sintered cermet body comprises 20 - 85% volume of a metal consisting mainly of W and/or Mo and 15-80% volume of stabilized Zr O2 the sintered cermet being coated with a protective layer consisting mainly of silicides. The oxide component may also contain up to 50% by weight of thorium oxide, hafnium oxide and/or titanium oxide. The Zr O2 is stabilized by the addition of up to 10% by weight of the oxide components of CaO or MgO. The protective silicide coating may be formed by either of the following methods: (1) heating the sintered body in an atmosphere of Si Cl4 and H2: (2) dipping into a Si containing alloy (3) packing in Si powder and heating: (4) applying Mo Si2 in a binder and heating.ALSO:A sintered cermet body comprises 20-85% volume of a metal consisting mainly of W and/or Mo and 15-80% volume of stabilized ZrO2 the sintered cermet being coated with a protective layer consisting mainly of silicides.
