Mediante la técnica de deposición física fase vapor (PVD) usando el método por magnetrón sputtering, se logró el recubrimiento en forma de monocapas de nitruro de vanadio sobre herramientas de acero rápido ASSAB 17® usados para el mecanizado por arranque de viruta en probetas de acero UNS G1020 para operaciones de cilindrado. Se realizaron cambios progresivos en los parámetros de corte tomando datos de temperatura sobre la herramienta, la probeta y el material removido para su posterior análisis y comparación con los datos obtenidos del mismo proceso realizado con herramientas sin ningún recubrimiento. Subsiguientemente se hizo la caracterización morfológica del recubrimiento mediante microscopio electrónico de barrido a las herramientas de corte. Se cuantificó la rugosidad de cada pobreta, característica fundamental para observar el aumento de la vida útil de la herramienta de corte y la reducción en los tiempos y costos de producción. Los resultados fueron contundentes, justificados en el incremento del desempeño en el arranque de material, mejor transferencia energética en el corte superior acabado superficial en las probetas.Palabras clave: Herramienta, mecanizado, vida útil.AbstractUsing the physical vapor deposition (PVD) technique with magnetron sputtering, we achieved monolayer-coating with vanadium nitride on ASSAB 17TM high speed steel tools used for machining UNS G1020 steal probes in turning operations by chip removal. We performed progressive changes in the cutting parameters, recording data related to temperature of the cutting tool, the graduated cylinder and the removed material for later analysis and comparison with similar data from the process performed with non-coated tools. Subsequently the morphologic characterization of the coating was carried out using scan electron microscope on the cutting tools. Graduate cylinder roughness was quantified to observe the lifetime extension and reduction of production cost reduction derived from the use of coated tools. The results were conclusive, justified in the increased performance in material removal, enhanced energetic transfer during cut and improved surface finished in the probes.Keywords: tool, machining; useful life.

The Face

High-speed steel (HSS) turning tools was designed and sharpened according to the angles of the complex shape cutting tools. CrAlTiN coating was deposited using unbalance magnetron sputtering plating technique. By dry turning tests, the wear characteristics and wear mechanisms of the face were investigated. The results show that the face wear of the coated HSS tools is obviously different from that of the uncoated tools, the crater width is smaller, the boundary is jagged and the lowest position is away from the major cutting edge. Adhesive wear and local adhesive wear are the main wear mechanisms.

Thin hard coatings are widely known as key elements in many industrial fields, from equipment for metal machining to dental implants and orthopedic prosthesis. When it comes to machining and cutting tools, thin hard coatings are crucial for decreasing the coefficient of friction (COF) and for protecting tools against oxidation. The aim of this work was to evaluate the tribological performance of two commercially available thin hard coatings deposited by physical vapor deposition (PVD) on a high speed tool steel (S600) under extreme working conditions. For this purpose, pin-on-disc wear tests were carried out either at room temperature (293 K) or at high temperature (873 K) against alumina (Al2O3) balls. Two thin hard nitrogen-rich coatings were considered: a multilayer AlTiCrN and a superlattice (nanolayered) CrN/NbN. The surface and microstructure characterization were performed by optical profilometry, field-emission gun scanning electron microscopy (FEGSEM), and energy dispersive spectroscopy (EDS).

Scratch Tests

In this research, structural, tribological and mechanical characterization of Nb and Ti doped diamond like carbon (DLC) films was carried out. Films were grown on M2 high speed steel (HSS), glass and silicon wafer substrates by pulsed DC physical vapor deposition – closed field unbalanced magnetron sputtering (PVD-CFUBMS) method. Structural characterization of the coatings was done by using Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and X-Ray Photoelectron Spectroscopy (XPS) tests. Tribological characterization was completed by conducting pin on disk tests, scratch tests and surface profilometry analyses on wear scars. Hardness measurements were done with nanoindentation tests. It was noted that there existed excellent adhesion between the coating and the substrate, which is evidenced by the high critical loads reached in scratch tests.

Increase Productivity

M2 steels, the typical Co-free high speed steel (HSS) possessing hardness level of 63~65 HRc, are most widely used for cutting tools. On the other hand, Co-containing HSS’s, such as M35 and M42, show a higher hardness level of 65~67 HRc and used for high quality cutting tools. In the fabrication of HSS’s, it is very important to control cleanliness and eutectic carbide structure of the ingot and it is required to increase productivity at the same time. Production of HSS ingots includes a variety of processes such as casting, electro-slag remelting (ESR), forging, blooming, and wire rod rolling processes. In the present study, electro-slag rapid remelting (ESRR) process, an advanced ESR process combined by continuous casting, was successfully employed to fabricate HSS billets of M2, M35, and M42 steels. Distribution and structure of eutectic carbides of the billets were analysed and cleanliness, hardness, and composition profile of the billets were also evaluated.
