Abstract
Wear-resistant materials and articles, wherein an amorphous material having a hardness of greater than about 1600 VHN is utilized to protect wear-susceptible portions of substrates or is itself made into a wear-resistant article. Amorphous materials having hardnesses greater than about 1600 VHN are found to have surprisingly great wear resistance and can be used to prepare wear-resistant articles. Particularly satisfactory results have been obtained with metal-metalloid systems such as W--Ru--B, Re--Mo--B, Mo--Ru--B, and Co--Nb--B materials.
