MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202617072730 A) filed by Hgans Ab Publ; and Hgans Germany Gmbh on June 11, 2026, for Solid Solution Held Chromium Carbides For Thermal Spraying And Method Of Making The Same.
Inventors include Bigdeli, Sedigheh; Memarpour, Arashk; Maroli, Barbara; Lanz, Oliver; and Baumgartner, Florian.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: In the present disclosure there is detailed a chromium-based powder consisting by total weight of powder of: Iron (Fe) : 15 – 18 wt%, Carbon (C) : 4.7 – 5.5 wt%, Tungsten (W) : 2.2 – 3.4 wt%, Molybdenum (Mo): 1.4 – 2.3 wt%, Boron (B) : 0.3 – 1.0 wt%, Silicon (Si) : 0.1 – 1.0 wt%, Niobium (Nb) : 0.35 – 0.60 wt%, the balance being chromium (Cr) and unavoidable impurities not exceeding 0.3 wt%, wherein nickel (Ni) and/or cobalt, if present, are only present as unavoidable impurities in amounts not exceeding 0.10 wt%, which powder, when used in a HVOF and/or a HVAF process, provides primarily chromium and tungsten carbides in solid solution in a BCC-phase iron- chrome stainless-steel alloy. As the matrix alloy is free of nickel and cobalt it provides a sustainable yet cost beneficial replacement for conventional binders for carbide products in particular for uses where nickel and/or cobalt contamination is undesired.
