Abstract
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.

Claim 1
Independent Claim
58 words
A wear-resistant composite material consisting of 40-80 volume % of a refractory chemical compound in particulate form with a size of 0.3-2 mm and consisting essentially of, by weight, 7-30% chromium, 40-60% titanium and 30-40% boron; and 20-60 volume % of an alloy matrix consisting essentially of, by weight, 10-35% nickel, 10-35% manganese and the balance being copper.
Claim 2
Dependent Claim
58 words
A wear-resistant composite material consisting of 40-80 volume % of a refractory chemical compound in particulate form with a size of 0.3-2 mm and consisting essentially of, by weight, 7-30% chromium, 40-60% titanium and 30-40% boron; and 20-60 volume % of an alloy matrix consisting essentially of, by weight, 10-35% nickel, 10-35% manganese and the balance being copper.
