摘要： An improved atomized powder metal material containing an increased amount of free graphite after heat treatment and/or sintering is provided. The powder metal material is typically a ferrous alloy and includes carbon in an amount of 1.0 wt. % to 6.5 wt. % and silicon in an amount of 0.1 wt. % to 6.0 wt. %, based on the total weight of the powder metal material. The powder metal material can also include various other alloying elements, for example at least one of nickel (Ni), cobalt (Co), copper (Cu), tin (Sn), aluminum (Al), sulfur (S), phosphorous (P), boron (B), nitrogen (N), chromium (Cr), manganese (Mn), molybdenum (Mo), vanadium (V), niobium (Nb), tungsten (W), titanium (Ti), tantalum (Ta) zirconium (Zr), zinc (Zn), strontium (Sr), calcium (Ca), barium (Ba) magnesium (Mg), lithium (Li), sodium (Na), and potassium (K).

摘要： A thermal spray powder is provided for use in a thermal spray technique, such as flame spraying, plasma spraying, cold spraying, and high velocity oxygen fuel spraying (HVOF). The thermal spray powder is formed by water or gas atomization and comprises 3.0 to 7.0 wt. % carbon, 10.0 to 25.0 wt. % chromium, 1.0 to 5.0 wt. % tungsten, 3.5 to 7.0 wt. % vanadium, 1.0 to 5.0 wt. % molybdenum, not greater than 0.5 wt. % oxygen, and at least 40.0 wt. % iron, based on the total weight of the thermal spray powder. The thermal spray powder can be applied to a metal body, such as a piston or piston ring, to form a coating. The thermal spray powder can also provide a spray-formed part.

摘要： A powder metal composition for high wear and temperature applications is made by atomizing a melted iron based alloy including 3.0 to 7.0 wt. % carbon; 10.0 to 25.0 wt. % chromium; 1.0 to 5.0 wt. % tungsten; 3.5 to 7.0 wt. % vanadium; 1.0 to 5.0 wt. % molybdenum; not greater than 0.5 wt. % oxygen; and at least 40.0 wt. % iron. The high carbon content reduces the solubility of oxygen in the melt and thus lowers the oxygen content to a level below which would cause the carbide-forming elements to oxidize during atomization. The powder metal composition includes metal carbides in an amount of at least 15 vol. %. The microhardness of the powder metal composition increases with increasing amounts of carbon and is typically about 800 to 1,500 Hv50.

摘要： An improved method of manufacturing a cast part by sand casting, permanent mold casting, investment casting, lost foam casting, die casting, or centrifugal casting, or a powder metal material by water, gas, plasma, ultrasonic, or rotating disk atomization is provided. The method includes adding at least one additive to a melted metal material before or during the casting or atomization process. The at least one additive forms a protective gas atmosphere surrounding the melted metal material which is at least three times greater than the volume of melt to be treated. The protective atmosphere prevents introduction or re-introduction of contaminants, such as sulfur (S) and oxygen (O2), into the material. The cast parts or atomized particles produced include at least one of the following advantages: less internal pores, less internal oxides, median circularity of at least 0.60, median roundness of at least 0.60 and increased sphericity of microstructural phases and/or constituents.
