WEAR-RESISTANT AMORPHOUS MATERIALS AND ARTICLES AND PROCESS FOR PREPARATION THEREOF

摘要

WEAR-RESISTANT AMORPHOUS MATERIALS AND ARTICLES, AND PROCESS FOR PREPARATION THEREOF 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.
