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) if present is only present as an unavoidable impurity in amounts not exceeding 0.10 wt%, which when used in a HVOF and/or a HVAF process provides primarily chromium carbides in solid solution in a BCC-phase iron-chrome stainless-steel alloy. As the binder 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. It is recommended that Figure 2 is published with the abstract.
