Abstract: Thermal spray coating compositions, methods of using thermal spray coating compositions, and remanufactured components are disclosed herein. A thermal spray coating composition can include about 7% to about 9% by weight aluminum, about 5% to about 7% by weight silicon, about 1% to about 3% by weight manganese, about 1% to about 14% by weight copper, with a remaining balance of iron. The thermal spray coating composition can include about 2% to about 12% by weight copper.

Abstract: A manufacturing process includes depositing a clad layer having a thickness greater than about 0.5 mm (0.02 in) on a surface of the component by hardfacing, and creating a heat affected zone directly below the clad layer due to the depositing. The heat affected zone may be a region of the component where a lowest hardness is lower than a base hardness of the component below the heat affected zone. The method may also include heat treating the component after the deposition such that the lowest hardness in the heat affected zone is restored to within about 15% of the base hardness of the component.

Abstract: A method of forming a layer of cladding material on a component includes performing a metal deposition process to deposit cladding material onto a surface of the component and onto a mold member. A metallurgical bond is formed between the cladding material and the component, but not between the cladding material and the mold member. The mold member may be removed after the metal deposition process, and the layer of cladding material can be processed to modify its shape.

Abstract translation: 在部件上形成包覆材料层的方法包括执行金属沉积工艺以将包覆材料沉积到部件的表面上并且到模具部件上。 在包层材料和组件之间形成冶金结合，而不是在包层材料和模具构件之间。 在金属沉积工艺之后可以去除模具构件，并且可以处理包层材料层以改变其形状。
