The spray and fuse coating have been metallurgically developed to perform at their peak after having undergone an intense fusing stage. This line of coating combines the ease of application of a thermal sprayed coating with the tough, high-stress wear characteristics of a hardface weld overlay. Although we consider these to be some of the highest-performing coating Hayden has to offer, the method of application demands careful consideration before specifying a spray and fuse coating. Our engineers can help you determine if this procedure is right for your application. High temperature process to be engineering in advance to for alloyed bond.
The fusing process literally bonds coating particles to each other, much as a welded material is bonded to a substrate. The result is a coating virtually free from the inter-particle spaces, or voids, and oxides that can cause a poorly applied thermal sprayed coating to fail when subjected to shearing or gouging wear. Fused coatings exhibit level of intermolecular bonding comparable to a welded material, but ,due to the carefully controlled application of material and heat, the applied coating experiences little chemical dilution , if any, from substrate. The coating interface exhibits characteristics similar to a brazed union.
