Powder Welding on Pumps
The application of Chrome Oxide ceramic powder or cord allows various pump parts to be either repaired or have their life expectancy increased with a very hard wearing coating.
Powder Welding involves an oxy-acetylene flame spraying followed by Fusing as a two stage process. After spraying, the coating is fused with an oxy-acetylene burner or for mass production. By using induction heating or a vacuum furnace, it allows the coating to be metallurgically bonded, extremely hard, corrosion resistant and resistant to impact and chipping. The powders used for Spray and Fuse hard-facing are typically compositions of Ni, Cr, Co, Bo, Fe, W and WC in varying blends.
Pumps can also be coated with Monel®, Inconel®, Stainless Steels by Flame Spray and Arc Spray methods. With Australia looking to be the market garden of the world, the Metal Spray and hard-facing processes will be playing a large part in its success.
