Sparay & Fuse Hardfacing
Available from A&A Company, Inc.
In this process, a Combustion Powder Spray gun is utilized to deposit a wide variety of materials on to a substrate. The powders used for Spray and Fuse Hardfacing are typically compositions of Ni, Cr, Co, Bo, Fe, W and WC in varying blends.
After the coating has been sprayed to a pre-determined thickness, an Oxygen-Acetylene torch, or a furnace, is used to hear the part to approximately 2000 degrees farenheit, fusing the coating within itself and to the substrate, thereby achieving a tru metallurgical bond. With this process, coating can be applied with a hardness up to 80Rc.
