Effect of chamber pressure on defect generation and their influence on corrosion and tribological properties of HIPIMS deposited CrN/NbN coatings
2018, Surface and Coatings TechnologyDefect growth in multilayer chromium nitride/niobium nitride coatings produced by combined high power impulse magnetron sputtering and unbalance magnetron sputtering technique
2017, Thin Solid FilmsCitation Excerpt :For this study the CrN/NbN coating was considered because of its wide industrial applications in recent years as a protective material due to the high hardness, good wear resistance and anticorrosive properties [1,21,22]. The excellent performance of nanoscale CrN/NbN coatings in various applications such as pump impellers, hydraulic valves, nozzles, pistons and sharp edges (cutting blades) has been previously demonstrated [22–24]. Surface imperfections have not proved to be detrimental in any of the above mentioned applications; however advanced coating applications (biomedical and industrial) demands thorough investigation of the growth defects to aid better understanding of their influence on the overall coating performance.
Effect of deposition method on tribological performance and corrosion resistance characteristics of Cr<inf>x</inf>N coatings deposited by physical vapor deposition
2017, Thin Solid FilmsCitation Excerpt :For example, Liu et al. studied the corrosion resistance of CrN and TiN coatings that were deposited in a magnetron sputtering system onto mild steel substrates [15,28,29]. Further, studies of the ability of chromium-based gradient, duplex and ternary coatings to improve wear resistance [22] and provide corrosion protection have been reported [30–36]. For example, Jagielski et al. [37] reported that 1.2 μm thick CrxN coatings synthesized by ion beam assisted deposition (IBAD) have the ability to provide corrosion and wear protection to stainless steel.
Wear mechanism of CrN/NbN superlattice coating sliding against various counterbodies
2013, International Journal of Refractory Metals and Hard MaterialsCitation Excerpt :High coating hardness has been observed for TiN/VN [11] and TiN/NbN [12,13] multilayer coatings. Both improved corrosion resistance and decreased erosive and abrasive wear rates due to multilayer structures have also been reported for CrN/NbN [14] and TiN/CrN systems [15]. The properties of these coatings are dependent on the period of the individual layers in the structure.
