Abstract

A composite comprises a first metal or alloy component having a thin refractory oxide layer on a first surface thereof. A second metal or alloy component has a second thin refractory oxide on the first surface thereof. Means are provided having a closely matched coefficient of thermal expansion to the first and second metal or alloy components for bonding the first and second thin refractory oxide layers and for electrically insulating the first component from the second component whereby thermal stress between the metal or alloy components and the bonding means is substantially eliminated.
