Wear resistance of vanadium-niobium carbide layers grown via TRD

Nb-V complex carbide coatings were produced on AISI D2 steel substrates using the thermo-reactive diffusion (TRD) process in order to improve the surface hardness and wear resistance of this tool steel. The carbide coating treatment was performed using molten borax with added ferroniobium, ferrovana...
