ABSTRACTSemiconducting TiO2 has some photoelectrochemical reactions under ultra-violet irradiation. These photoelectrochemical behaviors studied as possible protection from corrosion. TiO2 thick films were prepared on stainless steel by plasma-spray coating. The film thicknesses were 50∼100μm. The films were characterized by X-ray diffraction, and the diffraction patterns clearly showed a rutile type structure. The crystallization of the films depends on the spray coating conditions. We have investigated the protection properties of the films by measuring the electrode potential. The electrode potential of the films were reduced by about 250m V under ultra-violet irradiation. This potential drop value is sufficient for protection from the corrosion.

Approximate characterization of the complicated dynamics of plasma-spray coating processes may be useful in obtaining optimal coatings. The usual industrial method of obtaining such a characterization by experimental trial-and-error procedures may be more time-wasting and costly than a combined procedure of analysis and trial-and-error. This paper describes such an approximate analysis and presents the results in a simple graphical form. Thus, by using a few simplified differential equations which describe the fluid dynamics, temperature and velocity distributions as well as the degree of evaporation of the injected powder in the plasma jet, we illustrate our method for the specific case of spraying molybdenum particles in argon as the carrier gas. The results indicate the various limitations associated with major operating variables such as particle size, relative mass flow rates of gas and particles, plasma temperatures, and distances from the plasma gun. Evaporation losses of the powder are given in Fig. 7.
