| dc.description.resumo | 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 Electron Microscopy-SEM, and Energy Dispersion Spectroscopy-EDS. Drill performance was evaluated after machining SAE1045 steel specimens, using flank wear and hole diameter measurements. The performance test pointed to the viability of the treatment at 450°C, whose treated drill had a longer life than in the untreated drill, in addition to meeting the dimensional quality in all holes. In contrast, the other tools, nitrided at 500°C and submitted to the duplex treatment, they presented performance below the expected, not showing viability for application in these conditions. Additionally, it was observed the existence of a thermal gradient formed during the treatment | pt_BR |
