This paper experimentally investigated the effects of silicone oil on tribological behaviour AZ31B/86CrMoV7 contact pair under a pin-on-disk configuration. A commercial was used as an oxidation inhibiter for AZ31B at elevated temperatures to 300 °C. The wear mechanism explored by SEM morphologies worn surfaces. analysis revealed that can effectively minimize surface oxidation. Compared with dry...

A tamping machine is the key equipment of large coking coal cake forming in steelmaking industry, where loose compacted into a by reciprocating movement its hammer. In long-term friction process, third particle attached to surface pair hammer lifting mechanism often causes slip and wear plate, resulting an insufficient height hammer, uneven work collapse other problems. order avoid adverse effe...

In this work, a study of the wear transition regimes was carried out for a pin-on-disk sliding couple, involving two steels of different hardness and Cr contents. Dry sliding wear behaviour of the more highly alloyed stainless steel was dominated by adhesive wear and tribo-oxidation at relatively low sliding speeds and by mixed and adhesive wear at high speeds and loads. In contrast, oxidative ...

While the modification of surface contacts offers significant potential for friction reduction, obtaining an underlying consistent behaviour real-life experiments and virtual simulations is still ongoing challenge. In particular, most works in literature only consider idealised geometries that can be parametrised with simple analytical functions. contrast to this approach, current work describe...

Heat-assisted magnetic recording (HAMR) is expected to be a realistic next-generation technology for increasing the density of hard disks. However, layer heated above Curie temperature, and, as result, lubricant desorbed from disk by decomposition and evaporation, which causes problem it adheres air-bearing surface (ABS) smear. In this study, pyrolysis gas chromatography/mass spectrometry (Py-G...

In this research, a diesel engine lubricant, modified with Multi-Walled Carbon Nanotubes (MWCNTs) was evaluated. Carboxylic group functionalized MWCNTs were dispersed in 15W40 mineral oil for Diesel engines and retaining ring cylinder sleeve materials from F300 used tribological tests. The Nanofluid (0.1 0.5 1% wt.) rheological behavior characterized. Nanolubricants wt base evaluated on Pin-on-...

In friction stir welding frictional heat is generated by the rotating tool, sliding over the stationary plate along the weld centre. Tool being the only source of heat producing member, its geometrical design influences the heat generation rate. In this present work, effects of variation in tool shoulder and tool pin taper angles on thermal history during joining are analysed. Tools with triang...

Abstract In this study, the tribological properties of fused deposition modelling (FDM) 3D printed Polylactic Acid (PLA) is studied when it slides against a steel disk at various speeds. pins were using PRUSA MINI+ Printer according to recommended printing parameters. Pin on disc tests conducted normal load 20 N, sliding time minutes, and linear speeds 0.46, 0.58, 0.7 0.81 m/s . Experiment resu...
