“…100 These studies proved that soft coating was useful to improve tribological behavior of composites. It was also demonstrated through the research on the cutting performance of ceramic tools containing soft coatings by Xing et al 101 That PTFE is not only used as coating on Si 3 N 4 to improve the wear state but also applied to reduce wear by forming composite coating with Si 3 N 4 . 102 Adachi et al 103 found that COF was changed with the gas environment by affecting the chemical reactions between CN x coating and Si 3 N 4 during wear process.…”

Si3N4 ceramic matrix composites (SN‐CMCs) have been designed and widely used in many engineering fields under externally loading conditions. It is well known that the wear of materials is closely related to components’ mechanical reliability and service life. Understanding of the friction and wear performances is very important to provide insights into how to improve the wear resistance of materials. Coefficient of friction and wear rate, in general, are the most critical parameters of tribological behavior of materials. In this paper, friction and wear performances of SN‐CMCs are reviewed from the perspectives of doped phase, layered structure design, and laser surface texturing. The article describes the change of friction and wear performances of SN‐CMCs sintered with different additive phases. Tribological behavior of SN‐CMCs with engineering designed layered structure is also analyzed from the aspects of surface coating and gradient structure. In addition, friction and wear performances of SN‐CMCs under different lubrication conditions are also discussed. As an ideal processing method for hard and brittle ceramic materials, laser surface texturing has been proved to be an effective way to improve the wear resistance of SN‐CMCs. Researches have shown that the better wear resistance can be obtained by combining laser surface texture with layered structure. At the end of paper, studies on friction and wear performances of SN‐CMCs are summarized and prospected.

“…On the other hand, WS 2 films exhibit great thermal stability, a working temperature higher than that exhibited by MoS 2 (approximately 100 °C) and COFs between 0.02 and 0.06 under controlled conditions [8,9]. Nevertheless, similar to the other TMDs, when WS 2 is exposed to atmospheres that contain oxygen and water vapor, its intrinsic imperfections increase, rapidly deforming the crystalline structure; its lubricant properties and wear resistance then decrease dramatically [4].…”

“…Nevertheless, similar to the other TMDs, when WS 2 is exposed to atmospheres that contain oxygen and water vapor, its intrinsic imperfections increase, rapidly deforming the crystalline structure; its lubricant properties and wear resistance then decrease dramatically [4]. To address this issue, researchers around the world have performed experiments focused on doping this material with various metallic (Ni, Au, Pb, Ti, Al) and non-metallic (C, PbO, Sb 2 O 3 , ZnO) elements [1,9] to obtain a stable structure and to avoid excessive wear caused by triboxidation.…”

In this work, titanium doped tungsten disulfide thin films (WS 2 -Ti) were deposited on AISI 304 stainlesssteel substrates using the magnetron co-sputtering DC technique. Films were produced with varying titaniumcathode power from 0 to 25 W. The titanium content of the WS 2 structure was determined using energy dispersive spectroscopy (EDS), thereby obtaining a maximum of 10% for the sample grown at 25 W. X-ray diffraction (XRD) results indicated, for the pure sample, the presence of a hexagonal phase of high intensity on the (103) plane. However, with the addition of titanium, the WS 2 crystallinity was reduced; nevertheless, when the titanium content was equal to 10%, nanocomposite formation was promoted. This effect was observed in TEM (transmission electron microscopy) images. Finally, the tribological behavior was determined using a ball on disk (BOD) test. With this method, friction coefficient curves were obtained with respect to the number of cycles, allowing the measurement of friction coefficient values of 0.1 for the pure sample and 0.15 for the sample grown at 5 W. Because of the low thickness of the samples, all of them failed during the first cycles.

“…This is because that there will be a lot friction wear and adhesion wearbetween tool-chip contact area and tool-workpiece contact area. At the same time, with the more and more extensive application of difficult-to-cut materials like stainless steels, titanium and Ni base alloys which are widely used in aerospace components, engine parts, stationary power plants and medical applications [4], one problem is more and more outstanding, which is the high temperature at the center cutting area. The increase temperature in high speed cutting reduces machining accuracy and shortens tool service life, and even make the cutting process cannot be completed [5].…”

Advanced cooling technology is a crucial measure of thermal dissipation for high-speed end-milling. In order to get an appropriate cooling technology and decrease the negative effects of traditional wet cutting, internally cooled cutting has been paid more and more attention. Because of interrupted cutting and uneven force, there was few application and investigation on internally cooled end-milling. In the paper, the effect of the end-milling tool with different internally cooled channel structure has been researched by experiment and theoretical analysis. The experimental results indicate that the end-milling tool with double helix channels carried out best machined surface quality. And the experiment result was also been analyzed and explained by computational fluid dynamics simulation, which provides a basis for the applying of the high-speed internally cooled end-milling tool.
