“…The coefficient of friction (COF) for the 350 °C PIII + WC:C sample was 0.08, whereas for the 400 °C PIII + WC:C and 450 °C samples it was 0.15 (COF results shown in Figure 16). The COF results were lower than those reported by Laura et al, Boromei or Fuentes et al [10,41,42], where coatings of plasma nitriding and TiTiN or LTC/a-C:H were both measured to have values larger than 0.6 and a CrCN PVD was measured at 0.2. For a DLC with plasma pretreatment, COF values between 0.12 and 0.59 were obtained in the study by Tillman et al [30] The data for the volume loss in the wear tracks are shown in Table 9.…”

Diamond-like carbon (DLC) coatings are used due to their extraordinary tribomechanical properties, great hardness, high elastic modulus, high wear resistance, low friction coefficient and chemical inertness, which provide them with biocompatibility. Compared to other physical vapor deposition (PVD) coatings of transition nitrides and carbonitrides, DLC has limited adhesion, so it is necessary to develop new techniques to overcome this limitation. This work reports the results of scratch testing for the measurement of adhesion and of tests for wear resistance and nanoindentation in AISI 316L stainless steel coated with a WC:C coating, produced using novel high-power impulse magnetron sputtering (HiPIMS) technology with positive pulses. In addition, the use of a preceding surface modification technique, specifically plasma immersion ion implantation (PIII), was studied with the aim of optimizing the adhesion of the coating. The results show how the coating improved the tribomechanical properties through the use of positive pulse HiPIMS compared to conventional HiPIMS, with an adhesion result that reached critical load values of 48.5 N and a wear coefficient of 3.96 × 10−7 mm3/nm.

RESUMEN La vida en servicio de elementos de máquinas utilizados en la industria del gas y del petróleo puede ser extendida con el uso de recubrimientos que permiten mejorar las propiedades superficiales, como la resistencia al desgaste y a la corrosión. Los recubrimientos DLC son conocidos por su bajo coeficiente de fricción, alta resistencia al desgaste e inercia química. Las películas del tipo TiSiCN son cerámicas duras, por lo que otorgan una buena resistencia al desgaste abrasivo y erosivo. En este trabajo se analizan de forma comparativa estos dos recubrimientos cuando son depositados sobre un acero de media aleación AISI 4140. Se midió espesor y se hizo caracterización por XPS, DRX y espectroscopía Raman. Se realizaron ensayos de desgaste adhesivo tipo Pin-on-Disk y desgaste abrasivo (ASTM G65). Se evaluó la adhesión por Scrach Test. La resistencia a la corrosión se evaluó mediante cámara de niebla salina y ensayos potenciodinámicos. El DLC presentó un bajo coeficiente de fricción μ ~ 0,2, con una pérdida de volumen dos veces menor que el TiSiCN, mientras que este último presentó una resistencia al desgaste abrasivo 30 veces superior. La adhesión del TiSiCN también fue superior. El DLC mostró una mayor resistencia a la corrosión.

“…These metal-based substrates can be steel, stainless steel, or many others (such as Mg, Ti, or Ni). [23][24][25][26][27][28] However, many studies used iron-based substrates owing to their typical industrial applications. A notable feature of ceramic coatings is their significantly more noble electrochemical character than metals.…”

The inherent defective morphology of the physical vapor deposition (PVD) hard coatings limits their corrosion protective ability. We examined the impact of nitride‐based PVD coatings, including TiN, TiAlN, and CrN deposited on inert substrates by cathodic arc PVD method (CA‐PVD), on the galvanic corrosion of carbon steel. Their contribution was evaluated by zero‐resistance ammeter (ZRA) and electrochemical impedance spectroscopy (EIS) in 3.5 wt.% NaCl at pH 2 and 6, with and without aeration. The results indicated the prominent role of the coating type and the coupling environment on the generated galvanic currents. Immersion tests for the TiN‐, TiAlN‐, and CrN‐coated steel cross‐sections visually verified these results. The galvanic current contribution was distinct in environments where oxygen reduction is the dominant cathodic reaction. However, the layers' contribution to galvanic corrosion was minimal in deaerated acidic solutions, which is attributed to the high bonding strength of adsorbed intermediates to the coating surfaces.
