WELLSITE HARDFACING WITH DISTRIBUTED HARD PHASE AND METHOD OF USING SAME

A hardfacing (301) disposable on a surface of a component (306), such as a wellsite component, is disclosed. The hardfacing includes a surface portion and a bottom portion with a segregation line (428) defined therebetween. The surface portion and the bottom portion each include a matrix phase (434)...

Zusammenfassung:	A hardfacing (301) disposable on a surface of a component (306), such as a wellsite component, is disclosed. The hardfacing includes a surface portion and a bottom portion with a segregation line (428) defined therebetween. The surface portion and the bottom portion each include a matrix phase (434) including a matrix composition made of a metal alloy and a hard phase (436) 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 (426a) has a first concentration of the abrasion- resistant composition and the bottom portion (426b) 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. Rechargement dur jetable sur une surface d'un composant, tel qu'un composant de site de forage. Le rechargement dur comprend une partie surface et une partie fond avec une ligne de séparation définie entre celles-ci. La partie surface et la partie fond comprennent chacune une phase matricielle comprenant une composition matricielle composée d'un alliage métallique et une phase dure répartie dans la phase matricielle. La phase dure peut comprendre une composition résistant à l'abrasion constituée d'un matériau dur (par exemple, du carbure de vanadium). La partie surface présente une première concentration de la composition résistant à l'abrasion et la partie fond présente une seconde concentration de la composition résistant à l'abrasion, la première concentration étant supérieure à la seconde concentration de telle sorte qu'une surface résistant à l'usure est délimitée sur la surface du composant.
