In this study, titanium carbide nanoparticles (TiC) were coated on the surface of X40CrMoV51 (H13) hot work tool steel by laser coating method. Two stage laser cladding method was employed for coating processes. In the first stage, TiC powders were mixed in the phonelic resin and precoated at 50 µm thickness on the surface of steel substrate under vacuum. In the second stage, laser was directed to the surface and then hard coating layers were obtained on the steel surfaces. A CO2 laser with 2000 W power was operated at continuous-wave mode in the experiments. All laser cladding processes were performed under N2 atmosphere and various laser powers were selected to show the effect of laser power on the quality of coated steel surfaces. The morphology and phase structures were examined by scanning electron microscopy, Xray spectroscopy and optic microscope, respectively. The hardness of coating layers and bonding strength was defined with micro hardness tests and scratch test. The thickness of the coatings layers were measured in the range of 15-130 µm depending on laser powers. It is seen that crack-free, smooth and homogenous coating layers can be obtained at 237 W laser power. According to the hardness and micro-scratch tests results, hardness was improved significantly, and all coating layers had a good metallurgical strength to the substrate.

Abstract. The paper presents the results of mathematical modeling of physical processes in electronic devices such as helicon discharge and coaxial pulsed plasma thruster. A mathematical model of coaxial magneto-plasma accelerator (with a preionization helicon discharge), which allows estimating the transformation of one form of energy to another, as well as to evaluate the level of the contribution of different types of energy, the increase in mass of the accelerated plasmoid in the process of changing the speed. Main plasma parameters with experimental data were compared.

Abstract.Experimental results analyses of macroscopic contact angle change from the drop growth rate of distilled water on stainless steel substrates is presented. The value of contact angle is found to depend on the drop growth rate (m): contact angle decreases at m up to 0.02ml/s and increases at m more than 0.02ml/s. At the final stage of spreading the contact line pinning occurs, depending on the drop growth rate and surface roughness.
