Opis:: Vyzkumny Ustav Zeleznicni, a. s. (VUZ) followed a long-standing tradition and professional activity carried out by its direct forerunners - the last one was Vyzkumny ustav zeleznicni, o. z. as a branch of Ceske drahy, a. s. (CD). After VUZ has established itself at the position of a daughter company of CD, domestic customers as well as customers from the whole EU territory and other countries are offered a wide range of special services within the whole rail system - railway infrastructure and rail vehicles, especially in the sphere of testing activities and conformity assessment.

Opis:: This paper deals with the stress and temperature induced microstructure transformations in a soft bearing steel 100Cr6 after turning operation. Investigation is carried out through a technique based on Barkhausen effect. Evaluation of surface integrity via structure transformations, X-ray diffraction as well as microhardness inspection is carried out as well. Surface integrity is investigated with the respect to the variable tool wears and consequent mechanical and thermal loads applied on the inspected surfaces. Different surface microstructures caused by the mechanical and associated thermal aspects of the surface formation are discussed and correlated with the parameters obtained from the measured Barkhausen emissions.

Opis:: Current trends in modernization and miniaturization of ferroprobe sensors lead to replacement of amorphous ribbon cores with magnetic microwires. The miniaturization often causes degradation in the parameters of sensors, so, considering measurement of weak magnetic fields, it is necessary to explore noise parameters, temperature drift and stability of the magnetometer output value. The article deals with analysis of microwire sensor noise characteristics based on the experimental data processing. Using one second periodograms, the linear spectral density was processed. Obtained data are compared with corresponding parameters of a relax-type ferroprobe magnetometer.

Opis:: This paper deals with investigation of hard milled surface as a surface undergoing severe plastic deformation at elevated temperatures. This surface exhibits quite remarkable magnetic anisotropy (expressed in term of the Barkhausen noise) and differs from ground surfaces. The main reason can be viewed in specific structure and the corresponding domains configuration formed during rapid cooling following after surface heating. Domains are not randomly but preferentially oriented in the direction of the cutting speed at the expense of feed direction. The Barkhausen noise signals (measured in two perpendicular directions such as cutting speed and feed direction) indicate that the mechanism of the Bloch wall motion during cyclic magnetization in hard milled surfaces differ from surfaces produced by grinding cycles or the raw surface after heat treatment.

Opis:: We report on the development of new generation of magnetic relaxation sensors based on soft magnetic melt-spun ribbons with the composition $Fe_{63}Co_{21}B_{15}Cu$. The as-quenched amorphous alloy was subjected to thermomagnetic heat treatment in order to obtain sensor cores with optimized magnetic properties. The relaxation characteristics obtained for these cores by employing upgraded sensor electronics were compared to those based on the model simulations using Matlab-Simulink environment. The operational field range of new developed sensor core reached 300 μT within the frequency band 0-500 Hz, i.e. it is markedly extended as compared to the currently used cores based on the commercial VAC 25X material while keeping the similar sensitivity.
