Abstract: Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.

Abstract: Embodiments of wear resistant ferrous alloys are disclosed herein. In some embodiments, ferrous alloys can have a matrix which includes near spherical and hypereutectic borides and/or borocarbides while at the same time avoiding the formation of rod-like borides and/or borocarbides. In some embodiments, the wear resistant ferrous alloys can be used as a coating, such as a hardfacing layer, to add protection to different components.
