In Situ Formation of Extremely High Corrosion Resistant Ni–Ni3Si Nanocomposite Coating Using Spark Plasma Sintering and Subsequent Heat Treatment

Preparation and Characterization of Spherical Nickel Silicide Powder by Inductively Coupled Plasma Spheroidization for Additive Manufacturing

“…Recently, the application of metal silicides has gained more attention among researchers and various industries especially in additive manufacturing (AM) due to their excellent properties such as excellent corrosion and wear resistance, high strength and high-temperature oxidation resistance. [1][2][3] Such popular properties are unfavorably associated with characteristics of high melting point, high hardness, and low fracture toughness at low temperatures which pose challenges to the application of these materials in AM. [3][4][5][6][7][8] Additions of a second or third element are a good way to improve the properties.…”

“…[3][4][5][6][7][8] Additions of a second or third element are a good way to improve the properties. 1 Nickel silicide is one of the well-known metallic silicides with excellent physical and functional properties. Composites with the Ni element is a good way to improve the properties of silicide-based materials.…”

“…Composites with the Ni element is a good way to improve the properties of silicide-based materials. 1 However, due to the high melting point and hardness, powder metallurgical technologies are normally the most effective way for producing nickel silicides. Powders synthesized by traditional methods may have irregular size and shape, low powder flowability, and packing density.…”
