Composition dependence of the friction characteristics of Ti and Zr carboboride alloys in a wide temperature range

It is shown that the composition dependence of the wear rate of carboboride alloys at various temperatures has a minimum at the point corresponding to the eutectic composition.
Determinations of the variation of the hardness of these alloys with temperature have established that in the range 500–800°C alloys of eutectic composition surpass in hardness their components.
An investigation into the fine structure of the surface layers of TiC-TiB2 alloys subjected to rubbing tests at various temperatures has demonstrated that a dominant role in the formation of working layers is played by their TiB2 component. The eutectic alloy is characterized by the least change in substructure.
