Provided in one embodiment includes a multi-fully alloyed powder that provides a wear-resistant and corrosion-resistant coating on a substrate when applied by a thermal spraying process. The coating exhibits desirable hardness, toughness, and bonding characteristics in a highly dense coating that is suitable for a wide range of temperatures. The embodiment provides a method of forming a coating, the method comprising: providing a substrate; and disposing onto the substrate a coating, comprising: a powder-containing composition comprising an alloy, the alloy comprising a solid solution comprising nickel, and a first component comprising at least one transition metal element and at least one nonmetal element.
