Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

steel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for
