Method of forming a hardfacing layer on a machine component

摘要

A method (200) of fabricating a machine component is provided. The method includes preparing (202) at least a portion of a surface (114) of a machine component for receiving a sintered preform. The method also includes forming (204) a pre-sintered preform hybrid hardface mixture that includes combining a predetermined portion of at least one hardfacing material with a predetermined portion of at least one brazing material. The method further includes forming (206) a pre-sintercd preform. The pre-sintered preform has predetermined dimensions. The method also includes forming (208) the sintered preform and positioning (210) the sintered preform on the machine component. The method further includes fixedly (212) coupling the sintered preform to at least a portion of the machine component via brazing.
