Thermoplastic composites are acquiring more importance in various tribological applications due to their self-lubricity, low melting, and ease of fabrication. In this research article, processing via fused deposition modelling dry sliding wear behaviour neat short carbon fiber reinforced polylactic acid have been investigated. A series tests using a pin-on-disc apparatus was carried out by vary...

Abstract Carbon nanoparticle coatings on laser-patterned stainless-steel surfaces present a solid lubrication system where the pattern’s recessions act as lubricant-retaining reservoirs. This study investigates influence of structural depth line patterns coated with multi-walled carbon nanotubes (CNTs) and onions (COs) their respective potential to reduce friction wear. Direct laser interferenc...

The design trajectory parameters of 3D horizontal wells in X gas field are not uniform, the construction is random, and lack standardization enough to achieve rapid drilling. Based on analysis data difficulties completed well, according different types, by standardizing drilling tool assembly well design, making full use characteristics formation law, using supporting tools control sand carryin...

Vegetable oils are biodegradable and therefore good candidates for environmentally friendly base stocks. They have excellent lubricity, but poor oxidation and low temperature stabilities. For this study, synthetic lubricant basestocks with oxidative stabilities and pour points comparable with commercial synthetic lubricant basestocks have been prepared by reacting epoxidized soybean oil with Gu...

Non-road diesel engines are significant contributors to air pollution in the United States (USEPA, 2004). These engines emit particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and other pollutants. The Clean Air Non-road Diesel Rule was put in place to reduce emission levels from agricultural, construction, and industrial diesel powered equipment. This rule calls for a reduct...

While sulfir in diesel fuels helps reduce friction and prevents wear and galling in fuel pump and injector systems, it also creates environmental pollution in the form of hazardous particulate and S02 emissions. The environmental concern is the driving force behind industry’s efforts to come up with new alternative approaches to this problem. One such approach is to replace sulfur in diesel fue...

Although the compatibility of biodiesel with the key components of automobile engine such as cylinder, pistons, piston rings, connecting rods, bearings, etc. have posed a big challenge to tribologists, they have yet to come up with a solution to reduce tribological degradation of different metals as well as the used fuel. Some efforts have already been given to understand the corrosion and wear...

Petroleum prices are increasing day by day and for fueling we are completely dependent on the fossil fuels. Sources of fossil fuels are depleting continuously due to the increasing demand of petroleum products. Renewable carbon neutral transport fuels are necessary for environmental and economic sustainability. There are many options in this area, but unlike solar, nuclear, and fossil fuels, bi...

Cutting fluids are often used in the machining of titanium alloys to reduce processing temperature and maximize quality productivity. The permeability cutting fluid capillary tube directly influences effect lubrication on cooling performance. In this study, supercritical carbon dioxide cryogenic micro-lubrication (scCO2-MQL) is for auxiliary alloys. A model scCO2-MQL-assisted proposed establish...
