ABSTRACT:
Metal-ceramic composites may be prepared by treating the ceramic component of the composite with a second metal prior to subjecting the metal-ceramic composite to a sintering operation. By pretreating the ceramic component of the composite, it is possible to obtain a composite which will undergo sintering at an elevated temperature to form a composite which will possess desirable characteristics such as increased density, hardness and low thermal coefficient of expansion, thus enabling the composites to be utilized in a wide variety of applications.
