Description

technical field [0001] The invention relates to the technical field of preparation of wear-resistant materials, in particular to a composite wear-resistant material and a preparation process thereof. Background technique [0002] Abrasion resistant materials are often used in coating or hardfacing applications to protect the underlying material from friction, impact, fretting, and similar potentially damaging mechanical action. Wear-resistant coatings or hardfacing may include a uniform layer of hard or wear-resistant material. The wear-resistant materials prepared by the prior art are poor in compressive strength, flexural strength and wear resistance. Contents of the invention [0003] The object of the present invention is to provide a composite wear-resistant material and its preparation process, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following ...
