They were coated with WC–27NiCr and WC–10Co4Cr using the high velocity oxy-fuel (HVOF) method. The metal spray coating technology has the advantage in terms of the selection of materials for cost effectiveness and environmental effects of corrosion because the properties of the coat layer ...
The effect of heat treatment on the characteristics of WC-27 mass/100 NiCr sprayed coatings on 13/100CR steel made by the High Velocity Oxygen-Fuel Flame Spraying (HVOF) was studied. Specimens were heated to 673 K and held at 5, 10, 20 and 30 h in air. Corrosion resistance was ...
