A hardfacing disposable on a surface of a component, such as a wellsite component, is disclosed. The hardfacing comprises a surface portion and a bottom portion with a segregation line defined therebetween. The surface portion and the bottom portion each include a matrix phase including a matrix composition made of a metal alloy and a hard phase distributed in the matrix phase. The hard phase may include an abrasion-resistant composition made of a hard material (e.g., vanadium carbide). The surface portion has a first concentration of the abrasion-resistant composition and the bottom portion has a second concentration of the abrasion-resistant composition with the first concentration being greater than the second concentration such that a wear resistant surface is defined on the surface of the component.

Wellsite hardfacing with distributed hard phase and method of using same

A composite material and a methods of making and using the composite material, wherein the composite material provides improved wear resistance and fracture toughness to hard-facing and matrix materials for down hole drilling tools.
