Improvement of the Tribocorrosion Properties of Cemented Carbide (WC-Tic-Co) Samples with PVD Coating

This study aims to investigate the improvement of tribocorrosion properties WC-TiC-Co substrates by coating them with hard coatings such as AlCrSiN using cathodic arc deposition. is commonly used in fabrication machining and cutting tools; however, there are some materials titanium or stainless steel that difficult work with; furthermore, aggressive environments under high temperatures performance tools can be affected, a failure may occur. intended ensure correct any conditions. The were characterized glow discharge optical emission spectroscopy (GDOES), scanning electron microscopy (SEM) X-ray diffraction (XRD). Tribocorrosion, tribology corrosion tests performed evaluate samples. Furthermore, mechanical adhesive studied scratch nanoindentation tests. results showed improved samples combined good properties. These show possibility these coated most demanding applications.
