Abstract

A wear-resistant composite material incorporating a refractory chemical compound in particulate form and an alloy matrix. The particles contain between 7 and 30 wt.% of chromium, between 30 and 40 wt.% of boron, the balance being titanium, have a size between 0.3 and 2 mm and are present in an amount between 40 and 80 vol.%, the balance being the alloy matrix. The material has an improved resistance to wear and consists of comparatively cheap and widely abundant ingredients.
