Our aim was to highlight the activity concentrations of radon in four types water used for drinking: bottled water, tap spring and well region Kosovo (Prizren Suhareka). Radon were measured using Alpha GUARD PQ2000 PRO. The measurements show that arithmetic means ± standard deviations (Rn-222) concentration as follows: 1.5 0.4 Bq/L 2.8 0.6 10.2 1.3 10.3 1.4 water. average found be respectively. total annual effective dose AEDT: 7.9 2.1 µSv per year, is 52.6 6.9 52.9 7.1 year 14.1 4.0 year....
The aim of this research is the investigation compound layer formed by steel 16MnCr5 after gas nitriding. was carried out with metallographic methods – that is, optical microscopy and electron probe microanalysis (EPMA). thickness measured using microscopy. profile nitrogen (N) concentration determined a Jeol JXA-8900 RL microanalyzer. conditions EPMA were potential U = 20 kV distance 5 μm between two nearest points. for all samples an microscope. Based on results, kinetics activation energy...
This research aims to determine the depth of diffusion nitrogen in steel 16MnCr5 after gas nitriding. Nitriding was performed ammonia atmosphere at three temperatures (510, 550 and 590°C), with four different durations for each temperature. The techniques were metallographic electron probe micro-analysis (EPMA). According first method, optical microscope Neophot 30 firm Carl Zeiss Jena, surfaces all samples observed. nitriding layers photographed help a microscope, from which depths...
This study is concerned with experimental curves of: hardness, residual stress and concentration of nitrogen at the precipitation layer alloy steels after gas nitriding. The purpose this treatment that through to identify relationship causality between on one side, other, respectively nitrogen. Comparing shape slope these we can conclude that, diffused steel lattice, ferrite, a cause increased hardness layer. More point, as result diffusion, emerge which increase hardness. intensity depends stress.
