摘要: A hardfacing composition comprising an iron-based binder alloy; and a carbide phase sintered cast tungsten carbide, wherein the is present in quantity of at least 22% by weight, based on total weight phase, comprises particles having sizes range from 30 to 60 mesh. Also provided super dense one or more additional materials, 10 percent (% w), 16 40 Included are methods manufacturing such compositions downhole tools improved applied thereon.
