ABSTRACT:
A compound material for temperatures up to about 1250.degree. C. or 1350.degree. C., respectively, and a method for producing the same, are disclosed, including a pair of joined layers one of which is a corrosion- and high-temperature-resistant alloy, the other layer consisting of a refractory material with high strength at high temperatures. The layer having the weaker mechanical strength at high temperatures is thinner than the other layer, the ratio of layer thickness preferably being between 1:5 and 1:2. A further alloy layer may be provided on the opposite side of the refractory layer, thereby to define a three-layer laminate. A thin layer of diffusion barrier material, such as platinum or palladium, may be provided between the refractory and alloy layers. The method for producing the laminate includes the step of detonating an explosive layer to exposively clad the alloy layer on to the refractory layer.
