Abstract null null Aircraft tire suffers from high-speed friction due to harsh conditions in landing, which leads to high temperature and the short service life. So, the effect of different sliding speeds on the tribology behaviors of tread rubber was studied theoretically and experimentally. Firstly, high-speed friction and wear tests were carried out by using a self-developed high-speed friction testing apparatus. Then, a thermo-mechanical coupling model was developed to predict the friction t...

Abstract null null The wear and contact fatigue of involute modified gears under minimum quantity lubrication were investigated through updated contact path and measurement of the updated profiles. The results indicated that the wear depth of pitch line was not the minimum, there was relative sliding on the pitch line during the wear process and the surface damage had a great influence on it. Continuous wear moves the point of minimum sliding in direction of the addendum/dedendum and the wear mi...

Abstract null null Fractional approach to modelling cavitation erosion kinetics was proposed by the author over two decades ago as a response to incompatibilities in material resistance assessments following from the International Cavitation Erosion Test project. The current status of the methodology, with overview of research conducted so far as well as discussion of the approach potential and limitations, was summarized in a paper published by Wear in 2020. After recapitulating the background,...

Abstract null null The mechanical and tribological properties of three types of diamond like carbon (DLC) coatings, i.e., non-doped, Si-doped, and W-doped DLC, are evaluated. Dry reciprocating sliding wear tests were performed to evaluate the effect of sliding frequency/velocity on friction, adhesion, and wear. The degree of graphitization of non-doped and W-doped DLC increases with sliding velocity, which results in a lower coefficient of friction (COF), and a decrease in wear rate. Si-doped DL...

Abstract null null Double helical gears are widely applied in the aviation, marine and energy equipment, and generally required to be modified as the crowned since the machining error and assembling error of the gear drive are inevitable. The crowned gears usually operate in point contact mixed elastohydrodynamic lubrication (EHL), and adhesive wear has been one of the most prominent problems, but few previous researches were focused on this problem. In this work, a wear life prediction model of...

Abstract null null In this study, to investigate the effect of the hexagon friction block installation direction on the surface tribology and friction-induced vibration and noise (FIVN), tribological tests were carried out on a self-manufactured high-speed train brake dynamometer under different installation directions. Accordingly, a finite element (FE) model with material parameters and boundary conditions coinciding with the test rig was used to conduct complex eigenvalue analysis (CEA), and ...

Abstract null null In abrasive belt rail grinding, understanding the abrasive belt wear mechanisms is important for improving grinding accuracy and abrasive belt service life. Taking a single ceramic grit in a stable grinding state as an example, this study investigated the critical transition conditions and recognition methods between the different wear modes. Based on the crack growth equation, the critical transition condition from abrasion to fracture was modeled by calculating the stress ar...

Abstract null null This paper focused on the comparative study on the crater wear when cutting flake graphite iron (FGI), compacted graphite iron (CGI) and nodular graphite iron (NGI) because of the reported overwhelming difference in tool life. A series of turning experiments are conducted with FGI, CGI and NGI, with multilayer coated inserts under dry condition. The crater wear profiles obtained from the confocal microscopy are collected to construct the evolution of crater wear. Together with...

Abstract null null Titanium aluminide Ti48Al2Cr2Nb was tribologically tested on a pin-on-disk tribometer from −50 to 600 °C, using coated and uncoated carbide cutting tools as a pin. The goals were to characterise the wear and friction behaviour and to find the most efficient tool for turning processes. A transition from ploughing to plastic deformation and adhesive wear was observed as temperature raises. The friction coefficient reached the minimum value at 600 °C, mainly due to the lubricatin...

Abstract null null Superlubricity has numerous benefits in industrial applications, but its practical applications are restrained from its heavy dependence on special atmosphere environment and the use of low-dimensional materials. This paper reports a novel and facile method to macroscale liquid superlubricity for steel tribopairs, which realizes superlow friction almost right at the start of the test. Two diols of ethylene glycol (EG) and 1,3-propanediol (13-PD) are used as the base lubricants...
