Abstract:
Our research is focused on the changes in thin surface layer of the brake disk due to the impact of severe plastic deformation and heating by friction process. The aim of this study is to compare structure, chemical and phase compositions of the surface layer in depth up to several hundreds of nanometers in the no affected central part of brake disk and the part which was in contact with brake pads by braking.

Abstract:
Austempered ductile cast iron is part of a family of heat-treated cast irons. Isothermal hardening transforms ductile cast iron into ausferritic cast iron (ADI), which has the appropriate characteristics of strength, the impact strength and fatigue resistance. [..]

Abstract:
The paper analyses the structural modifications occurred in the welded joints from a Duplex stainless steel, delivered in solution annealed state in form of sheet with 12 mm thickness. As filler material it has been selected an electrode wire E 2209-16 with a diameter of 1.2 mm, which has a higher Ni content (8-10 %) compared to the base material (4.5-6.5 %) in order to promote the formation of austenite and to induce in the weld approximately equal proportions of ferrite and austenite.Also are capitalized the benefits of the pulsed current arc-welding regarding the precipitation reactions limitation of the intermetallic phase σ and of the nitrides in weld and heat affected zone (HAZ) which can affect both corrosion resistance and toughness..

Abstract:
The paper is dealing with microstructural characterisation and mechanical properties of thermally simulated parts of the heat affected zone in homogeneous weldments of T24 steel. The study has been targeted on the blunt peripheral weld joints of T24 steel between two tubes, which are an integral part of the production of membrane walls. [..]

Abstract:
The paper presents the models of temperature field, phase transformation kinetics, the calculation of thermal and structural strains in a steel element during multi-pass Gas Metal Arc Weld surfacing. The temperature field is described analytically assuming a bimodal volumetric model of heat source and a semi-infinite body model of the surfaced (rebuilt) work-piece. [..]

Abstract:
In industrial practice on various production stages of the fittings for overhead power line, there are many factors that cause the zinc coating thickness diversification, that in the next step determine its corrosion resistance. This effect is observed especially in the thermal cutting process. [..]

Abstract:
Cr2N0.62-11Ag nanocomposite coatings containing 11 wt.% of Ag solid lubricant were deposited on substrates made of Cr-V ledeburitic tool steel Vanadis 6 by reactive magnetron sputtering at a deposition temperature of 500 °C. The experiments consisted of long term annealing up to 24 h at temperatures of 300, 400 and 500 °C, respectively, in closed-air atmosphere. [..]

Abstract:
The technology of Laser Surface Re-melting (LSR) is used to modify the surface layer of bulk materials or coatings in order to improve their surface properties, usually wear resistance. In the case of thermally sprayed coating, its application leads to elimination of porosity and internal oxides on the coating splat boundaries. [..]
