Lubricating problems are common in many engineeringapplications, such as aerospace, ground mechanical equip-ment, and large aircraft carriers. Moreover, the high-performance lubricating materials are the key to ensure highrunning precision and stability for mechanical systems. Withthe rapid development of modern technology, various lubri-cating materials have been developed for different machiner-ies. These developments are geared toward improving theproperty of materials and allowing them to surmount severechallenges under extreme conditions (e.g., high/low temper-ature, special media, and unfavorable atmosphere) in thefields of aviation, space, nuclear energy, andmicroelectronics.The lubricating materials corresponding to the requiredconditions in these fields must be capable of working incorrosive environments and high/low temperatures for a longtime. However, because the conventional lubricating mate-rials cannot satisfy these application requirements, lubri-cating materials are currently facing a series of challenges[1, 2].
In recent years, much effort has been directed towardpreparing high-performance materials and coatings fortribological applications, such as laminated-graded self-lubricating composites [3, 4], composite-lubricating coatings[5], and DLC films with surface texturing [6]. In addition,nanomaterials and nanostructures, because of their specialdimensional effects, reveal totally different tribological andmechanical properties compared with traditional materials
[7, 8]. The combination of nanomaterials and lubricatingcomposites is a promising way to achieve the optimizationof lubricating materials [9]. Meanwhile, the emergences ofnew preparation technologies [10] and theoretical approaches[11] have hastened the development of an increasingly largenumber of new lubricatingmaterials and thus speeded up theindustrialization process of these materials.
In this special issue, five papers are devoted to themechanical and tribological performances of nanomaterialsand films. The carbon nanolayer, remained on the surfaceof Ti6Al4V alloy after ion implantation, was proved tohave an influence on friction reduction due to the self-lubrication property of the carbon nanolayer. Dual-coatedTiO2nanoparticles as water based lubricant additive and
cutting fluids additive provided excellent tribological prop-erties, which might be ascribed to the forming of a dynamicdeposition film during rubbing process according to surfaceanalysis. For DLC films, nanotribological properties suchas H (Nanoindentation hardness) and nanowear resistancewere highly correlated with ID/IG ratio and highly dependenton the films’ nanostructures. Hard and soft multilayeredSiCN nanocoatings with high hardness and toughness wereprepared by magnetron sputtering. Increased deformationaccommodation was achieved for such alternate hard andsoft layers as the thin hard layers slide relative to eachother due to shear deformation of low modulus layers. Thisspecial issue also contains a very interesting hypothesis about

developing an elastic property analysis model suitable forthree commonly used fabric liners through a theoreticalanalysis of the elastic properties.
We hope that readers will find in this special issue notonly accurate data and updated reviews on the tribologicalbehavior of advanced materials, but also important guidancefor the optimization of the advanced lubricating materials.
