摘要： A method for manufacturing a seal is disclosed. The method includes coating a sealing surface substrate of an annular main seal body of the seal with a layer of Molybdenum, and melting the layer of Molybdenum to fuse the layer of Molybdenum into the sealing surface substrate to form an alloyed outer seal layer. The alloyed outer seal layer forms a sealing surface of the seal.

摘要： A method of producing a hardened component includes forming a 3-dimensional (3D) structure using an additive manufacturing process. The method includes forming the 3D structure using the additive manufacturing process and defining one or more passages there within. The method further includes heating the 3D structure in a pre-defined chamber to increase a temperature of the 3D structure to a pre-determined value. The method thereafter includes performing at least one of: infusing the plurality of passages defined in the heated 3D structure with a gaseous medium for at least a pre-defined period of time, and quenching the plurality of passages in the 3D structure with a quenching fluid for a pre-defined period of time.
