Surface roughness is an important indicator of the quality machined surface. One methods that can be applied to improve surface ball burnishing. Ball burnishing a finishing process in which rolled over workpiece Defining adequate input variables ensure obtaining required typical problem scientific research. This paper presents results experiments investigate AISI 4130 alloy steel with high-stiffness tool and ceramic ball. The were conducted following randomized full factorial design for...
The assessment of the quality sediment from Great Backi Canal (Serbia), based on pseudo-total lead (Pb) and cadmium (Cd) content according to corresponding Dutch standards Canadian guidelines, showed its severe contamination with these two metals. A microwave-assisted BCR (Community Bureau Reference Commission European Union) sequential extraction procedure was employed assess their potential mobility risk aquatic environment. Comparison results different criteria for has led somewhat...
In the printing plate developing process, offset developer undergoes changes, as well enrichment by various chemicals, i.e. metals, organic binders and photosensitive compounds. The objective of this study was to investigate electrocoagulation/flotation (ECF) treatment efficiency for removal copper, turbidity substances from waste (WOPD). effect operational parameters, such electrode materials, current density, interelectrode distance operating time, studied. Also, response surface analysis...
Pyrite ash (PA) is created by burning pyrite in the chemical production of sulphuric acid. The high concentration iron oxide, mostly hematite, present ash, gives basis for its application as a source catalytic modified Fenton process anthraquinone dye reactive blue 4 (RB4) degradation. effect various operating variables such catalyst and oxidant concentration, initial pH RB4 on abatement total organic carbon, has been assessed this study. Here we show that degradation reaction was efficient...
This study is focused on dry longitudinal turning of AISI steel using CVD coated cutting inserts.The machining was conducted at different levels speed, feed, depth cut, corner radius, rake, inclination and approach angles.Surface roughness measured after each experiment, statistical analysis used to derive an empirical, regression model for arithmetical mean surface roughness.The theoretically minimize roughness, followed by additional verification experiments.The 95 % confidence interval...
This study attempts to determine the possibilities and limitations of immobilization galvanic wastes by their incorporation into clay-based materials. It focuses on effects several processing parameters such as temperature thermal treatment, relative amount sludge, physico-chemical aspects sample, fixing level relevant metals (Zn, Ni, Fe, Mn, Pb, Cu, Cr) in thermally treated samples. The effectiveness sludge inactivation was assessed water-leaching test conductivity measurements. In view...
This paper examines the impact of CO2 laser parameters on tensile strength, which is one most important properties packaging in process cutting material. The study was performed a material sample Fbb Board/Ningbo Spark C1S Ivory Board by examination influence four independent variables: grammage, speed, power, and resolution strength using definitive screening design. Optimum conditions variables that maximize were predicted validated accordingly. Results confirm speed are main mostly affect...
In this article an assessment of the sediment metal pollution (cadmium, copper, chromium, lead, nickel, zinc) in Veliki Backi canal (Serbia) was carried out using pseudo-total content, contamination factor (CF), load index (PLI) and enrichment (EF). The study also encompassed pore-water concentrations based on analysis simultaneously extracted metals (SEM), acid volatile sulphides (AVS) sequential extraction procedure. are likely to result harmful effects comparison with quality guidelines...
