Application of nitriding and duplex treatment on steel drills-HSS

The present study aims to evaluate the application of plasma nitriding (at temperatures of 450° and 500°C) and duplex treatment (conventional nitriding followed by TiN deposition, using the cathodic cage deposition technique). Samples were characterized by Vickers Microhardness Test, Scanning Electr...
