Production and characterization of niobium carbide coatings produced on tool steels by thermoreactive deposition/diffusion

In this work, niobium carbide coatings were deposited on AISIM2, H13, and D2 tool steels by thermoreactive deposition/diffusion. The carbides were obtained using salt baths composed of molten borax, aluminum, and ferroniobium at a temperature of 1020 °C for 4 hours. The coatings were observed via sc...
