Machinability study of stainless steel AISI 304 under the influence of copper oxide nanoparticles dispersed emulsifier cutting fluid
S. Ravi and P. Tamilselvam
Wiley
AbstractQuality machining on stainless steel AISI 304 is achieved by reducing the interface temperature generated due to high hardness and compressive frictional force. Temperature rise during the turning operation was observed to cause a weak tool nose, and machining surface. Enhanced lubricant properties can alleviate these issues and help reduce tool nose wear while increasing machined surface quality. Nano‐lubricants have been prepared to meet the functional requirements for machining. Emulsifier oil‐based nanofluids perform exceptionally well in heat transfer during machining. The present investigation focuses on copper oxide nanoparticles addition in “Society of Automotive Engineers 30” emulsifier oil at two different weight percentage: 1.5 wt.‐% and 2.25 wt.‐%, aiming to improve heat transfer and machined surface quality. In this experimental study, a computer numerical control machine tool, DCMT120404 insert, tool dynamometer, and infrared pyrometer are utilized for the machining operation. It was observed that 2.25 wt.‐% copper oxide mixed emulsifier‐nano cutting fluid exhibited minimum cutting force and work‐tool interface temperature while enhancing the surface quality.

In the present work, egg shell and Tungsten disulphide particles are reinforced in AZ31B alloy using friction stir process. Initially, the ES and WS2 particles are mixed at different weight ratios (25/75, 50/50 and 75/25) then are reinforced in AZ31B plates using a taper threaded FSP tool at rotation speed of 1000 rpm, axial load of 6 kN and traverse speed of 10 mm/min in hole method. The post macroscopic analysis showed that defect free hybrid surface composite is obtained with 75wt %ES and 25wt % WS2 particles reinforced in AZ31B alloy. The grain size is reduced from 15 µm to 5 µm due to the addition of 75wt% ES and 25wt% WS2 particles through FSP. The mechanical, corrosion and tribological responses of AZ31B/75ES/25WS2 hybrid surface composite are observed and are compared with FSPed AZ31B alloy without reinforcements and AZ31B base alloy. The microhardness is improved by 66% and 83% in FSPed AZ31B alloy and AZ31B/75ES/25WS2 hybrid surface composite respectively compared to the AZ31B base alloy. Similarly, the ultimate tensile strength is improved by 16% and 31% in FSPed AZ31B alloy and AZ31B/75ES/25WS2 hybrid surface composite respectively compared to the AZ31B base alloy but the % of elongation is decreased by 70% and 78% in FSPed AZ31B alloy and AZ31B/75ES/25WS2 hybrid surface composite respectively compared to the AZ31B base alloy. The corrosion rates of FSPed AZ31B alloy and AZ31B/75ES/25WS2 hybrid surface composite are decreased by 22% and 48% respectively compared to AZ31B base alloy. The dry sliding friction and wear responses are observed for AZ31B base alloy and AZ31B/75ES/25WS2 hybrid surface composite by varying the applied load (10 N, 20 N and 30 N) and sliding velocity (1.5 m/s, 2.6 m/s and 3.6 m/s) with constant sliding distance of 2000 m. In AZ31B base alloy, the wear mechanism is initially dominated by delamination and ploughing phenomena but at high sliding condition, the delaminated and worn out debris based tribolayer reduced the wear rate. In AZ31B/75ES/25WS2 hybrid surface composite, the wear mechanism is dominated by adhesive and delamination phenomena and the formed tribolayer decreased the wear rate at high sliding condition.

ABSTRACT In this study, investigation has been conducted in the focus of obtaining better surface finish in the electro discharge machining (EDM) of AZ91/5B4Cp magnesium composites using distinctive sort of anode viz. copper, tungsten–copper, brass, aluminum and 20Gr/AA6061 (GRAL-20) composites. The process parameters, pulse on time and current were performed to research the machining qualities through material removal rate (MRR) and tool wear rate (TWR). The machined composites were examined by optical microscopy (OM) and scanning electron microscopy (SEM). The formation of black spots was observed on machining with copper–tungsten and these black spots were not found when GRAL-20 was used as electrode. Machined with GRAL-20 electrode leads to the increase in spark gap, hence adequate flushing occurs; it eliminates re-melted layers on machined surface results in better surface roughness value. The results revealed that GRAL-20 electrodes posses better MRR followed by copper electrode whereas tungsten–copper exhibits better TWR followed by GRAL-20 electrode.

Environmental effects of adding aluminum oxide nano-additives on diesel engine fueled with pyrolyzed biomass oil–diesel blends

ABSTRACT The present study focuses on the investigation of environmental effects of adding aluminum oxide (Al2O3) nanoparticles as nano-additive in diesel-pyrolyzed biomass oil (PBO) blends. The PBO was extracted from jatropha seeds through the catalytic pyrolysis process at a temperature ranging from 450°C to 550°C. The esterification of PBO has been carried out using a catalyst in the presence of methyl alcohol to improve its physical properties and quality. The Al2O3 nano-additives were dispersed into PBO20 (20% of PBO and 80% of diesel) and PBO40 (40% of PBO and 60% of diesel) blends with a concentration of 50 ppm. The physical properties of test fuel blends were measured and compared with diesel. The engine emission tests were carried out using these blends at a constant speed of 1500 rpm by varying the load. The emission constituents such as CO, HC, and smoke were reduced. However, the emissions like CO2 and NO were increased by the addition of nano-additives compared to diesel.
