Abstract Current studies of a seawater axial piston pump mainly solve the problems of corrosion and wear in a slipper pair by selecting materials with corrosion resistance, self-lubrication, and wear resistance. In addit...

The Editor-in-Chief has retracted this article. This paper was submitted to the journal Physics and Chemistry of Solid State on October 13, 2021. On November 17, 2021, the article was checked by the Unicheck system an...

We want to make three comments to the article by Li et al. [1].The first one is the interpretation of the internal friction peak at 382 K, which they attributed to the Snoek effect, but other authors suggest that this ef...

Abstract Wheel polygonal wear can immensely worsen wheel/rail interactions and vibration performances of the train and track, and ultimately, lead to the shortening of service life of railway components. At present, whee...

Abstract To improve the quality and efficiency of Z-directional 3D preform forming, the Z-yarn frictional force distribution model of the preform and its wear mechanism were investigated. In this study, a tensile force m...

Abstract The hydro-viscous drive (HVD) has been widely used in fan transmission in vehicles, fans, and scraper conveyors for step-less speed regulation or soft starting. In the mixed friction stage, the contact, friction...

Abstract The current research of seawater hydraulic motor mainly focused on piston motor and vane motor, but seldom regarded low speed high torque seawater hydraulic motor. Low speed high torque seawater hydraulic motor ...

Abstract Tool wear is a critical challenge in titanium alloy friction stir welding (FSW). Vortex flow-based FSW (VFSW) is a potential solution for this issue because the VFSW process uses a similar material to the base m...

The antifriction properties of naphtene and polyglycol oils during little loading with lubrication of pair bronze-tungsten-carbide-alloy WK-6 (WK-ll) and graphelon-20-WK-6 (WK-11) and high loading with lubrication of pai...

Correlations between temperature of surface of friction, hardness of adjacent surfaces of steels, nonferrous metals and metal alloys and intensity of surround wear and coefficient of friction of polymer composite filled ...

The anti-wear properties of polymer composites based on polytetrafluoroethylene with not metallizedand metallized carbon fibers in conditions of friction and wear in over limit and limit of specific loads havebeen resear...

Abstract Friction stir welding is a promising solid-state welding technique. However, the issue of tool wear and break restricts its wider industrial application. To avoid the tool wear and break occurring in conventiona...

The aim of this study is to investigate the wear resistance of diamond-like carbon (DLC) films and wear debris of polyethylene using pin-on-disc testing on two groups of CoCrMo discs with DLC coatings. DLC coatings depos...

Abstract TiAlSiN is a potential protection coating for die steel to improve the surface hardness, anti-wear performance and suitability. In the present study, TiAlSiN is deposited on H13 die steel by high power impulse m...

The article deals with tribochemical influence of the surface activity of biosynthetic oils on the operational efficiency and reliability of lubricated friction nodes under the critical conditions. It is proved that the ...

Abstract Ceramic cutting inserts are a type of cutting tool commonly used in high-speed metal cutting applications. However, the wear of these inserts caused by friction between the workpiece and cutting inserts limits t...

Abstract The current investigation of refill friction stir spot welding (refill FSSW) Al alloy to copper primarily involved plunging the tool into bottom copper sheet to achieve both metallurgical and mechanical interfac...

Abstract The spherical plain bearing test bench is a necessary detecting equipment in the research process of self-lubricating spherical plain bearings. The varying environmental temperatures cause the thermal deformatio...

Abstract Copper particles emitted from braking have become a significant source of environmental pollution. However, copper plays a crucial role in resin-based braking materials. Developing high-performance braking mater...
