Organic-Sulfonate Functionalized Graphene as a High Temperature Lubricant for Efficient Antifriction and Antiwear in Water Based Drilling Fluid
نویسندگان
چکیده
The lubricity of drilling fluid resistant to high-temperature over 200 ℃ is still one the technological breakthroughs. In this study, graphene modified with sodium dodecylbenzene sulfonate (SDBS) was selected as a lubricant. Our results show that fluids have high stability after aging at 240 °C assistance SDBS/graphene. Excitingly, tribological performance test revealed SDBS/graphene exert excellent anti-friction and anti-wear properties. Compared base slurry, friction coefficient wear rate slurry are reduced by 76% 59%, respectively. deposited film composed graphene, Al2O3, SiO2, Fe2O3, FeSO4 actualized protection sliding contact zone, proving group on contributed prompt deposition bentonite then enhanced properties fluids. Overall, SDBS expected solve difficulty form effective poor under high-temperature.

متن کاملTribological Behaviors of Graphene and Graphene Oxide as Water-Based Lubricant Additives for Magnesium Alloy/Steel Contacts
The tribological behaviors of graphene and graphene oxide (GO) as water-based lubricant additives were evaluated by use of a reciprocating ball-on-plate tribometer for magnesium alloy-steel contacts. Three sets of test conditions were examined to investigate the effect of concentration, the capacity of carrying load and the endurance of the lubrication film, respectively. The results showed tha...
