Within the framework of the model of the nonlocal thermoelastic peak of low-energy ion, the formation of intrinsic stress in a carbon coating deposited from the vacuum arc plasma in the argon atmosphere is theoretically studied. It is shown that the flow ... see more

An arcjet plasma generator with a converging and diverging slit nozzle was constructed. This plasma source allowed us to directly observe the arc plasma in the discharge section, which provided useful information about a transition from ionizing thermal p... see more

EComposite hardfacings produced by Plasma Transferred Arc Welding (PTAW) and Submerged Arc Welding (SAW) possess a good combination of hardness, wear resistance and fracture toughness, thus providing high wear resistance. Although they cannot substitute a... see more

Self-fluxing NiCrBSi and related coatings received considerable interest due to their good wear as well as corrosion resistance at moderate and elevated temperatures. Hard tungsten carbide (WC) particles can be included in NiCrBSi for further increase of ... see more

The restoration method for the journals and wheel seats of the freight wagon wheelsets by means of plasma-arc metallization is presented and the results of the bench fatigue tests with the advisable operation life of the axles restored are given.

In this piece of study, the design and development of a low cost vacuum chamber with different ports are mentioned. I-V characteristic of Langmuir Probe is obtained using the primary data of the experimental set up for ‘single probe method’ in nitrogen se... see more

In this article, the camera settings for high-speed imaging of the arc, metal transfer, and weld pool in gas metal arc welding (GMAW) are investigated. The results show that by only changing camera exposure times and the selection of narrow bandpass filte... see more

A cold atmospheric pressure gliding arc plasma jet hasbeen developed and applied to disinfection. The size of the plasma output is about 6 mm in diameter and 10 mm in length. Ar gas at a flow rate of 10 slm and 25 W plasma power are used. Plasma discharge... see more

The article presents results of physico-chemical study of the deposit formed on the electrodes of an arc plasmatron when applying propane-butane mixture in the electrode gap. The studies were performed by means of optical, electronic, and Raman microscopy... see more
