Due to its strong corrosion resistance, high hardness, and ability maintain strength at temperatures, Monel-400 is utilized in the marine, aerospace, power plant sectors. alloy hard machine owing quick tool wear that causes poor dimensional accuracy. Therefore, an advanced measurement system required monitor insight of machining performance difficult-to-machine alloys like Monel-400. In present work, a new cutting technique presented increase efficiency cryogenic carbon dioxide (CO2) minimum...
It is crucial to find an effective, environmentally acceptable solution, such as bioplastics or biodegradable plastics, the world’s rising plastics demand and resulting ecological destruction. This study has focused on friendly production of bioplastic samples derived from corn starch, rice tapioca with various calcium carbonate filler concentrations binders. Two different plasticizers, glycerol sorbitol, were employed singly in a rich blend. To test differences physical chemical properties...
Abstract The paper deals with a study of relations between the measured Ra , Rq Rz surface roughness parameters, traverse speed cutting head v and vibration PtP RMS vRa generated during abrasive water jet AISI 309 stainless steel. Equations for prediction parameters were derived according to parameter head. Accuracy equations is described Euclidean distances. results are suitable an on-line control model simulating machining using accompanying physical phenomenon process which eliminates...
The paper presents the influence of cutting zone cooling method on selected indices chip formation and shape. In process turning 316L austenitic steel three methods have been considered: dry machining, MQCL + EP/AW. tests performed in accordance with Parameter Space Investigation. It has found that, when by addition EP/AW, friction coefficient rake face, thickening is reduced angle sliding increases as compared to machining method. reduction value +EP/AW due nano-particles based phosphate...
Antioxidants are a wide group of chemical compounds characterized by high bioactivity. They affect human health inhibiting the activity reactive oxygen species. Thus, they limit their harmful effect and reduce risk many diseases, including cardiovascular cancers, neurodegenerative diseases. also widely used in food industry. prevent occurrence unfavourable changes products during storage. inhibit fat oxidation loss colour. For this reason, often added to meat products. Many diet components...
Abstract Titanium and its alloys are widely utilized in the biomedical sector, they still exhibit poor tribological properties low wear resistance when employed against even weaker substances. The hardness, instability, high coefficient of friction, load-carrying capacity, insufficient to not only abrasive but also adhesive further disadvantages titanium alloys. focus this investigation is on performance Ti-6Al-4 V alloy contact with WC carbide balls subjected nanodoped cooling lubrication...
The present work deals with the relationship between energy consumption and surface integrity aspects in electrical discharge machining (EDM) of hot die steel. Initially, non-conventional experiments were performed 1.2344 steel material such as topography, power spectral density analysis, roughness etc. measured high end instruments. Then, data during was analyzed Labview software. Finally, two technological contributors established results compared different process parameters. demonstrated...
Most research on biochar has focused either the mechanistic or biophysical aspects, and there been relatively little into social applicability acceptance of as a soil enhancer in agriculture. However, whether to adopt their practice is ultimately farmers’ decision, willingness do so crucial. Here, we show producer’s perspective adopting biochar, using Polish farmers case study. Poland an interesting study because only recently attracted attention researchers, entrepreneurs, other...
Biochar as a carbon-rich highly porous substance has been proposed for use in agriculture and horticulture soil amendment. One of the main concerns this application biochar is its potential contamination with heavy metals (HMs) polycyclic aromatic hydrocarbons. The aim research was to access environmental risk used amendment on mesofauna (mites springtails). We conducted both field laboratory experiments wood-chip from low-temperature (300 °C) flash pyrolysis. free hydrocarbons (PAH),...
Breakout is one of the major accidents that often arise in continuous casting shops steel slabs Bokaro Steel Plant, Jharkhand, India. Breakouts cause huge capital loss, reduced productivity, and create safety hazards. The existing system not capable predicting breakout accurately, as it considers only process parameter, i.e., thermocouple temperature. also generates false alarms. Several other parameters must be considered to predict accurately. This work has multiple (casting speed, mold...
A better understanding of material deformation behaviours with changes in size is crucial to the design and operation metal microforming processes. In order facilitate investigation effects, needed be determined directly from characterizations. This study was aimed at manufacture a compact universal testing machine (UTM) compatible 3D laser-confocal microscope observe behaviour materials real-time. this study, uniaxial micro tensile conducted on three different thin (0.05 mm, 0.1 0.3 mm)...
