“…Sato et al [19], reported that as the bias voltage increased, the Al concentration in TiAlN coatings decreased, whereas the residual compressive stress and hardness increased up to -100 V, and decreased for higher bias voltages. Similar results were also published by other authors [20], [21]. In spite of the quantity of works reported about TiAlN coatings, a depth analysis of the relationship between structure and ing.cienc., vol.…”

TixAl1−xN coatings were grown using the triode magnetron sputtering technique varying the bias voltage between -40 V and -150V. The influence of bias voltage on structural and morphological properties was analyzed by means of energy dispersive spectroscopy, x-ray diffraction and atomic force microscopy techniques. As the bias voltage increased, an increase in the Al atomic percentage was observed competing with Ti and producing structural changes. At low Al concentrations, the film presented a FCC crystalline structure; nevertheless, as Al was increased, the structure presented a mix of FCC and HCP phases. On the other hand, an increase in bias voltage produced a decrease films thickness due to an increase in collisions. Moreover, the grain size and roughness were also strongly influenced by bias voltage. Propiedades morfológicas y estructurales de recubrimientos nitruro de titanio aluminio producidos por magnetron sputtering tríodo Resumen Se crecieron recubrimientos de TixAl1−xN empleando la técnica de magnetron sputtering tríodo, variando el voltaje de polarización entre -40 V y -150V. Por medio de espectroscopía de energía dispersiva, difracción de rayos x y miscroscopía de fuerza atómica, se analizó la influencia del voltaje de polarización sobre las propiedades morfológicas y estructurales de los recubrimientos. A medida que el voltaje bias se incrementó, se observó un aumento en el porcentaje atómico de Al, compitiendo con la concentración de Ti y produciendo cambios estructurales. A bajas concentraciones de Al, la pelćula exhibió una estructura cristalina FCC; sin embargo, a medida que le porcentaje de Al disminuyó, se pudo detectar una mezcla de fases FCC y HCP. Por otro lado, el incremento en el voltaje de polarización produjo una disminución en el espesor de las películas, debido al aumento en el número de colisiones. Además, el tamaño de grano y la rugosidad se vieron fuertemente afectados por el voltaje bías.Palabras clave: TiAlN; voltaje de polarización; sputtering; procentaje atómico; XRD.

The tribological behavior of the PVD-TiAlN coated carbide inserts in dry sliding against two-phase (α-β) titanium alloy,Ti6Al4V grade, was investigated. A modified pin-on-disc device was used to conduct experiments under variable normal load and sliding speed. Scanning electron microscopy (SEM) and X-ray micro-analyses by EDS were applied for observations of wear scars and wear products. It was revealed that the increase of sliding speed contributes to decreasing the friction coefficient under a low normal force, whereas the increase of the normal loading causes the friction coefficient is less sensitive to changes in the sliding speed and its values are equal to µ = 0.26-0.34. The adhesive nature of wear along with severe abrasive action of the Ti alloy were documented.

“…(83) It is concluded that for sliding materials with dominating severe adhesive wear, as for example for the couple TiAlN/stainless steel, the protective function of the TiAlN coating is not sufficient. (89) CrAlN coatings showed an evidently better corrosion resistance than TiAlN coatings. (38) TiAlN-based coatings, typically deposited as 2-5 µm thick films with hardness ranging between 3000-3300 HV, are thermally stable between 800-900°C and have the coefficient of friction against steel counterparts between 0.35-0.4.…”

“…High ionization sputtered TiAlN improves resistance to coating flaking and chipping as well as abrasive wear resistance. (89) The higher the aluminum content, the better the oxidation resistance and resistance to high-temperature wear. The aluminum in the coating material reacts with oxygen in the air and forms a passive Al 2 O 3 layer, which prevents the film from further intensive oxidation.…”
