During the thermal spray coating procedure, alloy 625 wires are employed. Alloy 625 wire is a nickel-chromium alloy that is utilized for its high strength, outstanding fabricability, joining, and corrosion resistant qualities. The service temperature of alloy 625 ranges from very low to 1800°F (982°C). Strength in alloy 625 is generated from the stiffness impact of molybdenum wire and niobium on the Ni-Cr matrix, hence precipitation hardening procedures are not required. This mix of components also contributes to alloy 625's outstanding resistance to a wide variety of corrosion and high-temperature effects such as carburization and oxidation. Alloy 625 wires have qualities that make them a great choice for seawater applications. These properties include resistance to pitting and crevice corrosion, high fatigue and tensile strength, and resistance to chloride-ion stress corrosion cracking.
Alloy 625 wires include products suitable for general use coating as well as supplementary products for specific coating applications. The resulting alloy wire coating has a high degree of structural integrity. Alloy wire forms a thick coating on the substrate's surface. This material selection is determined by the coating environment. All of the materials utilized for machine element restoration and bond coating are present in alloy 625 wires.
