Deposição de Nitreto de Titânio (TiN) com Gaiola Catódica em aço ferramenta AISI D2 e aço SINTER 30

Abstract

This paper presents an analysis of the efficiency of the deposition using the cathodic cage technique to perform surface coating of thin layers of Titanium Nitride (TiN) and its influences on tool samples of steel AISI D2 and SINTER 30. In this study, thermo chemical treatments were performed at the temperatures of 400°C in specifics conditions of pressure and duration. After treatment, the samples were classified and compared according to the specific conditions that the sample was exposed to, the characterization techniques used were the Scanning Electron Microscopy (SEM) to measure the thickness of the deposited layer, Optical Microscopy, to observe the microstructure of the nitride layers formed on the surface of the sample substrate, energy dispersive X-ray (EDS) to identify the chemical composition of the deposited film, Raman spectroscopy, to indicate the chemical phases present on the sample and X-Ray Diffraction (XRD) to prove the chemical phases present in the process. The results of these tests confirmed the deposition of a thin film of TiN in all treatment conditions proving the efficiency and versatility of this deposition technique.
