“…In our experimental conditions, a smaller RMS was obtained at a smaller R. Figure 3 shows the XRD spectrum of the TiN/C composite layer. Two significant diffraction peaks (111) and (200) corresponded to TiN (PDF 38-1420), whereas the weaker diffraction peak (002) corresponded to Ti (PDF 01-1197) [33,34]. This result indicated that a small R induced minimal changes in the diffraction peak of TiN (200), but R = 75% caused a significantly intensified and broadened peak.…”

Deposition techniques of direct current and radio-frequency magnetron sputtering were used to separately prepare TiN/C microstructural composite layer and fluorinated diamond-like carbon (FDLC) film on monocrystalline silicon. The aim was to investigate the effects of microstructural composite layers on the adhesion property of FDLC film. The results indicated that the TiN/C microstructural composite layer can distinguish from the substrate and the FDLC film. After adding the composite layers, the film-substrate binding force significantly increased. When the composite film were prepared at a partial pressure of 0.25, the binding force reached 30.5 N, which was greater than the value of 22.6 N for the sample without composite layers. TiN/C in the composite layers intensified the integration with silicon substrate because the C-C bond acted as a bridge linking the FDLC film to the silicon substrate. Furthermore, the bulges on the surface of the composite layers strengthened the physical bonding of the film with silicon substrates.

“…The iron oxides were very loose due to the volume expansion in the oxidation process, which did not effectively prevent the corrosion process. The addition of Al easily formed a dense Al 2 O 3 protective film on the Ni60-Al coating, which slowed down the corrosion progress to a certain extent, [27,28] were oxidized to form a TiO 2 protective layer, which further protected the integrity of the coating surface, [29] as shown in…”

Ni60 coatings with the additions of Al and Ti were prepared on S355 steel by laser cladding. The microstructure and phases of obtained coatings were analyzed using an ultra‐depth of field microscope and X‐ray diffraction, respectively. The effects of Al and Ti additions on the salt spray corrosion and electrochemical performances were investigated using a salt spray corrosion chamber and electrochemical workstation, and the corrosion mechanism was also discussed by the models of defect reactions and pitting corrosion. The results show that the crystal microstructure of Ni60 coatings with the Al and Ti additions is changed from dendritic to massive and granular. After the neutral salt spray test, the corrosion forms of Ni60, Ni60–Al, and Ni60–Al–Ti coatings are mainly pitting and intergranular corrosion in which the Ni60–Al–Ti coating exhibits the highest anti‐corrosion performance. The improvement of electrochemical performance for the Ni60–Al–Ti coating is attributed to the high compact structure and passive film, which provides fewer oxygen vacancies in the corrosion process due to the additions of Al and Ti.

“…The films exhibit no evidence of local delamination or microcrack formation, only some minor surface defects are observed. For comparison, crack formation was reported for 1.4-µm-thick sputter-deposited Ti/TiN multilayer coatings deposited by rf sputtering on aluminum substrates after 72 h of immersion in brine [66]. The films exhibit no evidence of local delamination or microcrack formation, only some minor surface defects, small pits of average diameter 0.4-1.4 µm, are observed.…”

Corrosion Resistant TiTaN and TiTaAlN Thin Films Grown by Hybrid HiPIMS/DCMS Using Synchronized Pulsed Substrate Bias with No External Substrate Heating

Ti0.92Ta0.08N and Ti0.41Al0.51Ta0.08N thin films grown on stainless-steel substrates, with no external heating, by hybrid high-power impulse and dc magnetron sputtering (HiPIMS/DCMS), were investigated for corrosion resistance. The Ta target was operated in HiPIMS mode to supply pulsed Ta-ion fluxes, while two Ti (or Ti and Al) targets were operated in DCSM mode in order to provide a high deposition rate. Corrosion resistance was investigated using potentiodynamic polarization and electrochemical impedance spectroscopy employing a 3.5% NaCl solution at room temperature. The 300-nm-thick transition-metal nitride coatings exhibited good corrosion resistance due to film densification resulting from pulsed heavy Ta-ion irradiation during film growth. Corrosion protective efficiencies were above 99.8% for both Ti0.41Al0.51Ta0.08N and Ti0.92Ta0.08N, and pore resistance was apparently four orders of magnitude higher than for bare 304 stainless-steel substrates.
