“…The dimensions of the discharge electrodes fabricated with Ernst 8 th profile were (120x20x5) mm3, while the preliminary samples fabricated in a cylindrical shape had dimensions of 1cm height and 1cm diameter. Figure (2) shows the mold used to fabricate the preliminary samples of electrodes and Figure (3) shows the mold used to fabricate the discharge electrodes.…”

In this work, laser discharge electrodes were fabricated using SiC composite as a base material. The electrodes were also fabricated by adding copper to the composite material under different formation conditions. These electrodes were employed to operate discharge system of a TEA-CO 2 laser. Operation parameters were studied considering several influences such as reduction factor, grain size, forming pressure, sintering time and temperature, and copper added ratio. Also, the electrical characteristics, such as conductivity, electric discharge uniformity and current pulse shape, were introduced. It is aimed to optimize the experimental conditions leading to produce the discharge electrodes suitable for stable and long-life operation of laser system.

“…The material has extremely high thermal conductivity, can withstand high electric fields before breakdown and also has high current densities and good mechanical properties. Also, silicon carbide is an excellent abrasive and it has been produced and made into grinding wheels and other abrasive products for periods over one hundred years [1][2][3].…”

The oxidation behaviour of Ni8Al and Ni25Cr coatings produced by high velocity oxygen fuel spray (HVOF) which were deposited on Fe-based alloys (CB2) was investigated. We simulated the service environment of the steam generator unit, and put the samples in a thermostatic tube furnace at 650[Formula: see text] in air with 20 wt.% water vapor for 1000 hours of cyclic oxidation. The formation mechanism are explained using SEM, XRD, and EDX. There were no spallations and obvious cracks in both coatings. Ni25Cr coating generated a better protection oxides scale than that scale on Ni8Al. The behavior and mechanism of the oxide scale formation had an important influence in coatings and we have discussed these phenomenons in the study.
