Mechanical properties and oxidation resistance of CrAlN/BN nanocomposite coatings prepared by reactive dc and rf cosputtering

Tribological and electrochemical performances of Cr/CrN and Cr/CrN/CrAlN multilayer coatings deposited by RF magnetron sputtering

“…CrAlN/BN coatings show superior oxidation resistance compared to CrAlN coatings. After annealing at 800 1C in air for 1 h, the hardness of CrAlN coatings decreased to 50% of the as-deposited ones; in contrast, the hardness of CrAlN/ BN nanocomposite coatings stayed the same, or in some cases increased to about 46 GPa, as revealed by Nose et al [16]. Recently, Li et al [18] developed a ZrO 2 /CrAlN multilayer and obtained excellent mechanical properties at elevated temperatures.…”

“…In terms of tribology, adhesion, and electrochemical properties, these coatings show better performance than their single-layer counterparts. CrAlN-based multilayered films with reasonable properties, such as CrAlN/AlON [14],CrN/CrAlN [15], CrAlN/BN [16] and TiAlN/CrAlN [17], have been developed. In addition to improving the tribological, adhesive, and electrochemical properties of the coatings, the mechanical properties can also be improved.…”

Preparation of boron nitride nanosheet-coated carbon fibres and their enhanced antioxidant and microwave-absorbing properties

“…These attributes render BN highly suitable in coating carbon bres and enhancing the antioxidant and microwave-absorbing properties of such material. 8,12,[15][16][17] Currently, chemical vapor deposition (CVD) and the dip-coating method are mainly used to coat carbon bres with BN. 14,[18][19][20] However, the CVD route usually requires hazardous and expensive precursor chemicals, whereas the dip-coating method is a complex process with a long preparation cycle.…”

Effect of CrYN/TiBN coating on friction performance and corrosion resistance of 316 stainless steel in artificial seawater

“…The addition of B to CrN-based coatings has been extensively studied [16,22,23]. Jahodova et al [24] prepared a CrBN coating using an unbalanced magnetron sputtering system and found that the CrBN coating structure presented irregular and discontinuous crystallite boundaries , compared to the CrN coating and the coating compactness was improved, which could effectively hinder the corrosive medium from penetrating the substrate, showing higher corrosion potential and smaller corrosion current density.…”
