“…These findings can be explained by the behaviour of the corrosive solution which acts as a lubricant, as it was reported by other authors [19]. When the sample surface is in contact with the aqueous solution, a hydrated layer which acts as a lubricant is formed.…”

“…In addition, molybdenum disulfide (MoS 2 ) is a popular solid lubricant used widely in machinery equipment to reduce or eliminate various wear damage [32]. Titanium nitride (TiN) coating is also widely used due to its high Friction 6(1): 32-46 (2018) | https://mc03.manuscriptcentral.com/friction hardness and high adhesion strength that enhance the surface properties under wear and corrosion conditions [33,34]. Thus, conducting an experimental research to investigate the anti-loosening performance of these typical coatings will provide theoretical support and engineering guidance to prevent loosening of bolt-connected structures.…”

This paper investigates the self-loosening of threaded fasteners subjected to dynamic shear load. Three kinds of typical coatings, PTFE, MoS 2 , and TiN applied to bolts and nuts, are tested in this investigation. The study experimentally examines the loosening mechanisms of fasteners and assesses the anti-loosening performance of the three tested coatings based on their tightening characteristics, loosening curves, and the damage of thread surface. Additionally, the anti-loosening performance of the three coatings is compared under different load forms. The results indicate that the PTFE and MoS 2 coatings have significant anti-loosening effect, whereas the anti-loosening performance of TiN coating is not satisfactory. It is also found that an appropriate increase of the initial tightening torque can significantly improve the anti-loosening effect. In addition, the microscopic analyses of PTFE and MoS 2 coating reveal that a reduced initial tightening torque leads to fretting wear on the thread contact surfaces of fasteners, thereby aggravating the damage.

Our study of ternary Mo-Zr-N thin layers is novel with the objective of improving certain mechanical and tribological characteristics and of finding the appropriate stoichiometry to have the microstructure, which orientates to the desired properties, using the characterization techniques: SEM, XRD, EDS, XPS, WDS and similar methods as well as nanoindentation, alternative tribometry and scratch test. The morphological study of ternary Mo-Zr-N coating shows that the (111) orientation of texture is preferred essentially due to residual internal stresses. During the development of the Mo-Zr-N deposits, we have noticed that the addition of Zr results in multiphases consisting of binary ZrN, MoN and MoZrN nitrides with a prism-shaped structure. The coefficient of friction is low for Mo-N coating and low zirconium levels. The Young's modulus takes values almost very close that is indicated for values below 100 at.% of Zr. The crystalline structure does not affect the resistance capacity of the material. The introduction of zirconium particles destabilizes the compound because zirconium atomic radius (0.138 nm) is higher than that of molybdenum (0.126 nm), and the lattice is distorted that explains these residual stresses.Keywords: microstructure, morphology, texture, hardness, Young's modulus, covers, PVD.
