... is an efficient pore-forming agent and completely removed, and the porosity of the PTFE increases with the increase of the CA content. The oil-impregnated porous PTFE exhibits an excellent tribological performance, an increased wear resistance of 77.29% was realized in comparison with neat PTFE. Originality...

... these issues. Design/methodology/approach Thermal vacuum molding technology was adopted to prepare PI porous material with different structures by changing the content of the pore-forming agent to control pore size and porosity of the PI material. PI oil-bearing materials were obtained by vacuum oil...

... Emerald Group Publishing Limited 2012 Porosity Wear Friction Copper Tribology Powder metallurgy Self lubricating bearings Journal bearings are one of the most important parts in rotating equipments, which can be grouped into two types considering lubrication mechanism...

... better than the conventional lubricant. The findings indicate that the negative effect induced by the porosity can be neutralized by the positive effect caused by the magnetization parameter. Further, this paper suggests that there is scope for enhancing the performance of the bearing system by choosing...

... Limited 2006 Porosity Fluid dynamics Nomenclature ψ permeability coefficient In the present paper an analytical approximate pressure field in finite porous journal bearing is proposed. This kind of approach for analysing the behaviour of a system is more effective than...

...Cem Sinanoğlu Purpose The purpose of this paper is to investigate pressure distribution of the journal bearings with aluminium shafts with varying surface porosity in varying revolutions using experimental and neural network approach. Design/methodology/approach The collected experimental data...
