The induction motors supply by converters leads to a distorted regime accompanied by some parasite torques and some supplementary losses. These aspects are emphasized further on because their quantitative determinations ...

The paper presents the results of the laboratory research on the chemical composition and crystallographic texture in 3% Si steels and their influence on the level of magnetic losses in the final sheet. The magnetic ...

The fretting corrosion behaviour of untreated Ti-6Al-4V alloy in artificial saliva solution was evaluated based on the change in open circuit potential (OCP) measured as a function of time. Fretting corrosion experiments ...

The paper presents the results of the research on the influence of the evolution hardness scheme rolled steel, for the cold-rolled strip steel St 12. St 12 is intended for the manufacture of cold rolled strip stamping ...

The paper presents a method to establish a link between the shear stability index and service behaviour of motor oils. A standardized method for shearing stability establishing is combined with appropriated curve fitting ...

The papers presents the wear results of testing a set of composites PA + 1% black carbon + x% micro glass spheres, where x is the micro glass sphere concentration (x=0, 5, 10, 20, 30wt) using a pin-on-disc tribotester, for ...

The goal of this paper is to test the effect of odification process of liquid steel with 4-7% silicon content, in the course of pouring out from steel-smelting furnace into ladlet, on macrostructure. The research settled ...

The influence of technological parameters on the structure of nickel layers electrodeposited on a copper substrate in a Watts bath has been studied. The complex influence of current densities, temperature and pH values ...

Modern structures of bridges and viaducts require dynamic isolation systems, designed to eliminate or mitigate the destructive effects of intense traffic and seismic activity on these constructions. This paper studies ...
