Abstract:
Eutectic ceramic Al2O3-ZrO2-SiO2 also termed Eucor (as a top coat) and CoNiCrAlY (as a bond coat) coatings
were sprayed onto the surface of recently developed fine-grained cast polycrystalline nickel-based superalloy
Inconel 713 LC by means of water stabilized plasma (WSP) and atmospheric plasma spraying (APS)
techniques, respectively. Specimens were subjected to isothermal oxidation at 1050 °C for 10, 50, 100, 200
and 500 hours in ambient atmosphere, prior to which a half of the as-sprayed specimens was annealed at the
temperature of 950 °C for 10 hours. [..]

Abstract:
This paper tries to determine the possibilities of application of the high temperature oxidation of cast iron as a
way of surface preparation before hot-dip zinc galvanizing and presents also results of corrosion resistance
tests of zinc coatings created after high temperature oxidation of grey cast iron (with flake graphite). Research
was focused on elements of overhead power lines - the jaw-chuck (screw-bow). [..]

Abstract:
The paper deals with evaluation of PVD functionally graded coatings based on Cr-Al-N, TiN and Ti-Al-N.
Coatings were deposited in the following combinations: CrAl/CrAlN, Cr/CrN/CrAlN, nitriding/Cr/CrN/CrAlN,
nitriding/TiN/AlTiN and nitriding/AlTi/AlTiN. As main criteria for coatings properties and quality comparison
methods of scratch test and nanohardness measurement were selected. [..]

Abstract:
In this work, the microstructural changes of nickel coated aluminium and hydronalium substrates were
investigated after the heat treatment above the melting point of pure aluminium. The 99.0Ni powder was used
to produce the coating using high velocity oxyfuel spraying on 5 mm thick 99.5Al and AlMg3 sheets surface.
As-sprayed samples were annealed in the temperature range of 660 - 800°C in ambient atmosphere. [..]

Abstract:
The content of this article is comparing the results of measurement of residual stresses using the X-ray
diffraction and Barkhausen noise.
These two processes are often used in academic research. Currently, they are no longer in use except for
when the output control of real heavy-duty machine parts is required to be measured. [..]

Abstract:
In terms of corrosion protection, metal passivity is a very important phenomenon, as it leads to slower corrosion process in oxidative environments. This phenomenon is of particular advantage in power plants, where electrochemical corrosion, especially on surfaces of components, occurs very often. [..]

Abstract:
Series of anodization experiments was conducted on pure aluminium (99,95 Goodfellow) substrates with the aim to map the possibilities and evaluate available techniques. Oxalic acid electrolyte was used for anodization at different voltage levels ranging from 20 to 60V, while current was always measured continuously during the experiment. [..]
