Synergistic lubrication behavior of TiN coatings integrated with CNTs for oil and water lubrication
The titanium nitride (TiN) coating was deposited on the M50NiL substrate by using a multiarc ion plating technique to enhance tribological performance under high contact stress. The microstructure and mechanical properties of the TiN coating were characterized and results demonstrated that the hardness and modulus of elasticity were enhanced to 33 GPa and 400 GPa, respectively. The tribological behavior of TiN coatings sliding against Si3N4 ceramic was investigated by using a ball-on-disc tribometer. Under dry friction, the wear resistance property was improved by 60.5 % after TiN deposition at high contact stress of 2.3 GPa. Meanwhile, carbon nanotubes (CNTs) nano-lubricants with good dispersion stability were prepared. Under aqueous lubrication, the coefficient of friction (COF) and wear scar diameter (WSD) decreased by 15.6 % and 8.7 %, respectively, after adding 0.2 wt% CNTs when TiN coatings slid against Si3N4 ceramic. Under oil lubrication, the COF and WSD decreased by 5.5 % and 12.6 %, respectively with the addition of CNTs. The findings contributed to the practical application of CNTs as additives in hybrid ceramic bearings lubrication.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
