The SiO2:TiO2 hybrid biodegradable nanolubricant for sustainable machining: The stability, thermo-physical and tribology perspectives
The increase in awareness of environmental issues and economic concerns has enabled the emergence of sustainable machining termed Minimum Quantity Lubrication (MQL). However, the extreme conditions of highspeed cutting hard-to-cut materials have posed new challenges for MQL machining. Thus, the Nano...

| 總結: | The increase in awareness of environmental issues and economic concerns has enabled the emergence of sustainable machining termed Minimum Quantity Lubrication (MQL). However, the extreme conditions of highspeed cutting hard-to-cut materials have posed new challenges for MQL machining. Thus, the Nano MQL (NMQL) is introduced. In this research, hybrid SiO2:TiO2nanoparticles are dispersed in a biodegradable base oil, and the stability, thermo-physical properties, and tribological perspectives are comprehensively investigated. Five volume concentrations of hybrid SiO2:TiO2nanolubricants ranging from 0.01 % to 0.1 % volume concentration were investigated and compared against the base oil. In summary, 0.1 vol% hybrid SiO2:TiO2in biodegradable base oil has demonstrated characteristics of potential advanced lubrication in MQL machining application |
