    摘要: A hardfacing composition comprising a carbide phase and a matrix phase, The carbide phase comprises mono-tungsten carbide in a quantity of greater than 50 percent by weight, based on the total weight of the carbide phase. The matrix phase comprises iron and nickel. The nickel is present in a quantity in the range of from 0.5 to 20 percent by weight, based on the total weight of the matrix phase. Also included are methods of applying such hardfacing compositions to a downhole tool and downhole tools having such hardfacing compositions applied thereon.
