  • ELECTRO-FORMED SHEATH FOR USE ON AIRFOIL COMPONENTS
    Publication number: 20100014964
    Abstract: An article for protecting an airfoil component includes a sheath having an outer side and an inner side that forms a cavity for receiving a leading edge of the airfoil component. The sheath is made of cobalt and phosphorous to protect the leading edge of the airfoil component from erosion.

  • ARTICLE HAVING COBALT-PHOSPHOROUS COATING AND METHOD FOR HEAT TREATING
    Publication number: 20090178736
    Abstract: A method of processing an article having a substrate and a cobalt-phosphorous coating disposed on the substrate includes heat treating the article. At least one physical characteristic of the cobalt-phosphorous coating is altered using the heat treating to thereby change a performance characteristic of the article. For example, the article may be an actuator component having a bore or a shaft that is movably disposed at least partially within the bore.

  • Lubricated metal bearing material
    Publication number: 20070269151
    Abstract: A method of forming a bearing coating includes the steps of depositing a porous layer on a substrate and depositing a lubricating material within pores of the porous layer. The porous layer and the lubricating material form a bearing coating on the substrate. The bearing coating includes between about 1 vol % and about 20 vol % of the lubricating material with the balance being the porous layer.

  • Low cost, environmentally favorable, chromium plate replacement coating for improved wear performance
    Publication number: 20070172695
    Abstract: A coating which improves the wear performance of a part is described. The coating is applied over an article such as a part or a workpiece using an electroplating process. The coating broadly includes a cobalt material matrix with a hardness of at least 550 HV and a plurality of carbide particles distributed throughout the cobalt material matrix. The cobalt material matrix may be a cobalt-phosphorous alloy. The particles interspersed throughout the matrix may be chrome carbide or silicon carbide particles.
