In this paper, a construction microwave induced plasma jet(MIPJ) system was used to produce a non-thermal plasma jet at atmospheric pressure, at standard frequency of 2.45 GHz and microwave power of 800 W. The working gas Argon (Ar) was supplied to flow through the torch with adjustable flow rate using flow meter regulator. The influence of the MIPJ parameters such as applied voltage and argon gas flow rate on macroscopic microwave plasma parameters were studied. The macroscopic parameters results show increasing of microwave plasma jet length with increasing of applied voltage, argon gas flow rate where the plasma jet length exceed 12 cm as maximum value. While the increasing of argon gas flow rate will cause increasing into the argon gas temperature, where argon gas temperature the exceed 350 ? as maximum value and study the effect of gas flow rate on the optical properties

Argon Plasma Jet

In this study, method for experimentally determining the electron density (ne) and the electron temperature (Te) in the atmospheric Argon plasma jet is used; it is based on optical emission spectroscopy (OES). Boltzmann plot method used to calculate these parameters measured for different values of gas flow rate. The results show that the electron temperature decreasing with the increase of gas flow rate also indicates an increasing in the electron density of plasma jet with increasing of gas flow rate.

Low Pressure Plasma Spraying

Very low pressure plasma spraying has been attracted attention due to special properties of the expanded plasma jet which may probably deposit specific and unique structure coatings, such as columnar structure coatings. The forming of the coatings is affected by plasma generating and working conditions. These operating parameters such as arc power, plasma gas flow rate, and chamber pressure have influences on pressure, enthalpy and temperature of plasma jet. In this work, an enthalpy probe is applied to measure the enthalpy of argon-hydrogen plasma jet generated at chamber pressure of 3000 Pa and 50Pa. The results showed that the temperature of plasma jet reached to 11000 K at 25 mm from nozzle exit, and then dropped slowly to 7000 K at 400 mm.
