Abstract A hot dip (Zn) – coating formation is carried out in the industry conditions. Two types of steel substrate are applied to experiment. morphologically different coatings obtained, accordingly. also laboratory conditions for making some additional explanations revealed phenomena. The thickening - phase sub-layer observed details determine time transition from stable into meta-stable solidification. Fe-Zn diagrams and equilibrium calculated, respectively. diagram dissolution...
Abstract Two different steel substrates are applied to the hot dip (Zn) - coating formation. The influence of substrate composition on thickening is recorded. Morphologies both coatings compared each other. transition from stable into meta-stable solidification revealed. criterion for competition between and justify analyzed transition.
The effective design of energy-saving electric motors with efficiency class IE4 and higher requires the use material characteristics that take into account core shaping process.Therefore, it becomes necessary to analytical or numerical models change local properties Fe-Si material.The aim work is indicate a useful model for estimating magnetic permeability material, as well understand reasons these changes.For this purpose, low-loss ferromagnetic materials cut guillotine laser were...
The paper presents the investigation of expansibility an Al-Si alloy in form a protective coating applied on steel substrate and as conventional cast, respectively. Examinations were carried out temperature range troom÷220°C using diffractometric technique based reflections (311), (222), (400), (331) from Al solid solution. It was demonstrated that exhibited better thermal compared to its expansion coefficient close standard values for alloys same chemical composition. For lower by approx....
Abstract The subject of research is car exhaust system piping made chromium–nickel steel grade AISI304L with a unique, complex shape that was obtained by hydroforming technology. purpose the to determine relation between microstructure features, surface condition, hardness and stresses on external as determined sin 2 ψ X-ray method. We found were tensile correlated hardness, i.e. they greater where higher. Moreover, longitudinal showed relationship pipe wall thickness, while circumferential...

Experimental measurements do not allow for a unique determination of the concentration profiles, e.g., in case multi-layer systems. The measured elements at alloy/scale interface is an average alloy and scale near spot beam [1]. knowledge boundary necessary understanding corrosion alloys. This essential obstacle experimental techniques can be overcome by computer modelling. Namely, combining different methods (non-unique measurement with modelling). Danielewski-Holly model interdiffusion has...
