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:
Corrosion resistant coatings must exhibit high density (low porosity), good adhesion to the substrate and of course low penetration of oxides. This paper deals with corrosion resistance comparison of six corrosion resistant coatings, which are frequently used in power plants. [..]

Abstract:
In many research articles dealing with tribological characteristics of sliding couples measured by Block-on-Ring test, the discontinuous course of the test appears in order to evaluate cumulative mass loss during the test. According to the ASTM G-77-05, the wear rate is supposed to be determine after the end of the test without interrupting, by evaluation of volume loss based on the measurements of wear scars geometrical characteristics.

Abstract:
The effect of friction stir welding on the microstructure and mechanical properties of copper and Cu-30Zn brass alloy was investigated by choosing fixed rotational speed of 950 rpm with welding travel speeds of 190 and 235 mm/min for both the copper and brass alloys. Microstructural investigations showed very fine grains with some deformed grains in the stirred zone and some coarser grains in the thermo-mechanically affected zone and base metal; whereas, no obvious HAZ was detected in welds.

Abstract:
The hot deformation behavior of NIMONIC 80A was studied in the temperature range of 900 ~ 1200°C by employing the hot compression tests with the strain rates varying between 0.02~20 s-1. The results showed that the strength during hot compression increased with increasing the strain rate and decreasing temperature. [..]
