2.0mm Corrosion Resistance 316SS Metal Spray Wire HRB90

Thermal Spray 316SS/316L Wire for Corrosion Resistance

Product Introduction:

316 stainless steel wire specifically designed for arc spraying. It produces a dense, well-bonded coating with excellent machinability and wear and corrosion resistance. 316 SS is widely used for machine element repair, dimensional restoration and wear resistance applications. It has high shrink characteristics and should not be used for coatings over 0.075 inched thick.

Thermal Spray Coatings are produced by projecting a molten stream of particles onto the base material. On impact these particles deform and solidify to form splats, and these splats mechanically lock onto the surface. There are numerous ways of generating the stream of molten particles using an electric-arc, plasma or a combustion process.

Depending on the process it is possible to procuce coatings of pure metals, alloys, ceramics and ceramic metal composites (cermets), and coating thickness generally varies between 0.1 and 2.0 mm. The adhesion and cohesion of a thermal spray coating is purely mechanical, which has certain advantages and disadvantages.

The main advantage is that there is no metallurgical compatability issue between the substrate and the coating, and it is therefore possible to apply a wide variety of coating materials onto essentially any substrate (e.g. bronze and cast-iron). The heat input into the base materials is also limited, and it is therefore possible to apply a thermal spray coating to a heat-sensitive substrate (e.g. heat-treated HSLA steels like 4140 and martensitic stainless steel) with no risk of softening or distortion. The main disadvantage is that the adhesive and cohesive strength of a thermal spray coating is relatively low, making coatings susceptible to damage from high mechanical loads (such as point or impact loads), cyclical loads or thermal stresses.
