“…The most common layered material used in combination with texturing is MoS2. However, studies have been performed on WS2 [241,[245][246][247][248], WS2/Zr [245,249], Cr-WS2 [250], graphite/graphene/carbon-nanotubes (CNTs) [167,233,240,[251][252][253][254][255] , CaF2 [248,256], and hBN [248]. Images of textured surfaces coated with MoS2 and graphite are shown in Figure 15.…”

Surface texturing and solid lubricants have demonstrated the ability to substantially reduce friction and wear under dry conditions. In recent decades, these two technologies have been combined to leverage the advantages of both for superior tribological performance. This review article first summarizes the state-of-the-art regarding surface texturing and solid lubricants, including soft metals, polytetrafluoroethylene, diamond-like carbon and 2D layered materials. Then, the synergy between surface textures and solid lubricants is discussed, with particular emphasis on the underlying mechanisms. Finally, gaps in the existing understanding of these synergies are identified and opportunities for future research are suggested.

“…The friction coefficient of this lubricant decreases gradually with increasing temperature and exhibits an excellent lubricating effect even at 1000 °C [22]. The performances of microhole-textured carbide tools filled with CaF 2 was elaborated by Song et al [23]. They found such materials suitable for promoting machining performance.…”

Surface properties of modern materials are usually inadequate in terms of wettability, adhesion properties, biocompatibility etc., so they should be modified prior to application or any further processing such as coating with functional materials. Both the morphological properties and chemical structure/composition should be modified in order to obtain a desired surface finish. Various treatment procedures have been employed, and many are based on the application of non-equilibrium gaseous media, especially gaseous plasma. Although such treatments have been studied extensively in past decades and actually commercialized, the exact mechanisms of interaction between reactive gaseous species and solid materials is still inadequately understood. This special issue provides recent trends in nanostructuring and functionalization of solid materials with the goal of improving their functional properties.

“…In the case of typical difficult-to-cut materials, keeping high machined surface quality and improving machining efficiency has always been a key issue [ 28 ]. Considerable efforts have been made to improve the cutting performance of carbide tools in conditions without cooling and lubricating fluids and at elevated cutting speeds, when the carbide tool is subjected to more severe friction and wear, leading to the reduction of service life [ 29 ]. Accordingly, fracture toughness and hardness are the key characteristics of cutting tools.…”

The paper presents results of investigations on the binderless nanostructured tungsten carbide (WC) cutting tools fabrication and performance. The scientific novelty includes the description of some regularities of the powder consolidation under electric current and the subsequent possibility to utilize them for practical use in the fabrication of cutting tools. The sintering process of WC nanopowder was performed with the electroconsolidation method, which is a modification of spark plasma sintering (SPS). Its advantages include low temperatures and short sintering time which allows retaining nanosize grains of ca. 70 nm, close to the original particle size of the starting powder. In respect to the application of the cutting tools, pure WC nanostructure resulted in a smaller cutting edge radius providing a higher quality of TiC/Fe machined surface. In the range of cutting speeds, vc = 15–40 m/min the durability of the inserts was 75% of that achieved by cubic boron nitride ones, and more than two times better than that of WC-Co cutting tools. In additional tests of machining 13CrMo4 material at an elevated cutting speed of vc = 100 m/min, binderless nWC inserts worked almost three times longer than WC-Co composites.
