“…Therefore, such an oxide layer could decrease the shear strength and in turn the frictional forces between the tested surface and the counterpart, reducing adhesive/delamination wear and resulting in a friction coefficient which is not only lower (Table 4), but also more stable (lower fluctuations of the friction curve in Figure 9). It is worth underlining that oxidation may be considered as a desirable event whenever a thin lubricious layer forms [35][36][37]. Further studies are needed to evaluate the positive effect of this oxide layer on coating wear resistance.…”

Thermally-sprayed Fe-based coatings have shown their potential for use in wear applications due to their good tribological properties. In addition, these kinds of coatings have other advantages, e.g., cost efficiency and positive environmental aspects. In this study, the microstructural details and tribological performances of Fe-based coatings (Fe-Cr-Ni-B-C and Fe-Cr-Ni-B-Mo-C) manufactured by High Velocity Oxygen Fuel (HVOF) thermal spray process are evaluated. Traditional Ni-based (Ni-Cr-Fe-Si-B-C) and hard-metal (WC-CoCr) coatings were chosen as references. Microstructural investigation (field-emission scanning electron microscope FESEM and X-Ray diffractometry XRD) reveals a high density and low oxide content for HVOF Fe-based coatings. Particle melting and rapid solidification resulted in a metastable austenitic phase with precipitates of mixed carbides and borides of chromium and iron which lead to remarkably high nanohardness. Tribological performances were evaluated by means of the ball on-disk dry sliding wear test, the rubber-wheel dry particle abrasion test, and the cavitation erosion wear test. A higher wear resistance validates Fe-based coatings as a future alternative to the more expensive and less environmentally friendly Ni-based alloys.

“…Today several components of engines and power trains in automobiles are coated with wear and friction-reducing materials to increase their lifetime, reduce fuel consumption and prevent corrosion [183]. Since more than 10 years for the base materials of these components there is an increasing trend to lightweight materials like aluminium or magnesium [135].…”

“…Thin hard coatings can have a positive influence on the fatigue and the corrosion fatigue behavior of mechanical components, especially for relatively hard steel substrates [13][14][15][16][17][18][19][20][21][22][23]. For these reasons, PVD and CVD coatings are nowadays adopted also for other advanced applications in addition to manufacturing, including but not limited to automotive components [24][25][26][27][28], aeronautic gas engines turbine and compressor blade protection [29,30] and biomedical applications, due to the improved corrosion protection and biocompatibility granted by thin hard coatings [31].…”

Abstract:In the present manuscript, an extended review on the state of the art on the experimental and numerical characterization of the fatigue behavior of Physically Vapor Deposited (PVD) and Chemically Vapor Deposited (CVD) thin hard coatings is presented. The current application and development fields of PVD and CVD treatments are analysed, focusing on the advantages granted by the adoption of these coatings for corrosion protection on various materials and components. The most recent experimental research results related to the fatigue behavior of PVD and CVD coated specimens are reported. Fatigue strength values are presented for various coating processes on different substrates, including hard steel as well as aluminium and titanium light alloys. Corrosion fatigue effects on coated specimens are presented where available, in order to evaluate the coating effectiveness in aggressive environments. An overview on the current state of development of theoretical and numerical models for the characterization of coated components and for the maximum number of cycles to failure is proposed to the reader.
