The path of international accounting convergence is, unanimously accepted by all decision makers of the international financial reporting environment, as being the best solution towards reducing differences in international ...

In most environmental pollution problems, the pollutant is released to the environment by the, almost always, turbulent flow of a carrier fluid. The pollutant mixes with the surrounding fluid (air or water) and undergoes ...

Paper is based by nitrocarburizing experiments made on laboratory plant. For experiments were used different samples of steel at different nitrocarburizing regimes. Influence factors were: temperature and ammonia ...

The main purpose of this paper is the comparative analysis of the behavior of frontal couplings with Nd-Fe-B permanent magnets in difficult environments, specific to metallurgy – such as environments with magnetic powders ...

This paper investigates the effects of adding alumina nanoparticles in the electrolyte bath on surface topomorphologies and structure of electrodeposited nickel. The influence on the corrosion process in NaCl solutions ...

For steel nitriding, treatment time is a important factor. Gas and plasma nitriding are usual method to increase surface properties by nitriding. A close retort is used. Total time for treatment are higher because are ...

Researches made on welded and nitrided samples from stainless austenite steel types show that nitriding thermo chemical treatment can be applied also for welded joints. As a result of the treatment, a diffusion layer ...

Nitriding at low temperatures, 450-500oC of austenic stainless steels lead to the obtaining of the tough layers over 1000 HV005 but having thicknesses of tenths of microns. Moreover, nitriding at 500ºC has determined the ...

The start-up friction coefficient in hydrodynamic bearings, used by engineers in the design of bearings, is most often issued from an approximation. Several studies can be found in the literature on this topic but most of ...
