Abrasive Wear Resistance of HVOF Sprayed - Scientific.Net

The aim of the current study was to elaborate and compare abrasive wear resistance of thick metal matrix based deposited coatings. To produce metal matrix composite (MMC) coatings, experimental powders made by mixing commercial nickel and iron based powders with recycled hardmetal powder were used. The usage of recycled hardmetal as an initial material can significantly decrease the cost Application of a pulsed atmospheric arc plasma jet for low In the plasma jet, the electrical energy of HV pulses is converted into heat in the pulsed arc (see Section 3.1 for details). In this arc plasma zone, the plasma gas is heated. The powder injector forms the powder suspension into a stream and provides this stream with the speed needed to penetrate the arc plasma

Application of a pulsed atmospheric arc plasma jet for low

In the plasma jet, the electrical energy of HV pulses is converted into heat in the pulsed arc (see Section 3.1 for details). In this arc plasma zone, the plasma gas is heated. The powder injector forms the powder suspension into a stream and provides this stream with the speed needed to penetrate the arc plasma Application of design of experiments to plasma Arc Welding The experiments were conducted based on five factors, five-level CCD matrix to optimize the experimental conditions. Lakshminarayan et al. (2008c) predicted the Dilution of Plasma Transferred Arc Hardfacing of Stellite on Carbon Steel using RSM. Characterization of high current pulsed arcs ranging The influence of current waveform parameters on the arc properties are analysed and discussed. Keywords:lightning arc, pulsed arc, plasma diagnostics, optical emission spectroscopy 1.

Introduction Plasma Transferred Arc (PTA) is the only thermal spray process that results in a metallurgical bond with the substrate steel. As the atomized feedstock crosses the plasma arc and the particles melt a thermal spray forms and the energy of the arc also forms a melt pool in the substrate Efficiency Characteristic of Plasma Synthetic Jet Actuator The greatest weakness of the plasma synthetic jet actuator is low working efficiency. In this paper, a novel sequential discharge (trigger discharge/pulsed direct-current discharge) power supply is designed, and the efficiency characteristics of the plasma synthetic jet actuator are analyzed in detail. The total working efficiency is divided into three subefficiencies:discharge efficiency

Study on Factors Effecting Weld Pool Geometry of Pulsed

Pulsed current Micro Plasma Arc Welding is used to joint thin sheets of AISI 304L sheets, which are used in manufacturing of metallic bellows and diaphragms. In this article the effects of pulsing current parameters on weld pool geometry namely front width, back width, front height and back height of pulsed current micro plasma arc welded AISI 304L stainless steel sheets was analyzed.
