Coatings flame-sprayed

The expander turbine is designed to minimize the erosive effect of the catalyst particles stiU remaining in the flue gas. The design ensures a uniform distribution of the catalyst particles around the 360° aimulus of the flow path, optimizes the gas flow through both the stationary and rotary blades, and uses modem plasma and flame-spray coatings of the rotor and starter blades for further erosion protection (67).

The top of the reaction chamber is hinged to permit access to the lower electrode (platen) that holds the wafers. This arrangement is illustrated in Figure 20. The platen is anodized, while the upper electrode is bare aluminum. The upper electrode housing is flame spray coated with aluminum oxide to eliminate electrical discharges above the upper electrode. The platen has pockets to accept wafers and maintain them in fixed positions as it rotates.

A prerequisite for good resistance to corrosion is that the protective coating must be dense and free from pores. Flame-sprayed coatings, with their low density and numerous oxide inclusions, are therefore unsuitable in many cases for exposure to aggressive media. Plasma-sprayed coatings are denser and more homogeneons. 

Because of the experience at the KIVCET plant at Portovesme, Italy, chloride attack at the bottom part of the radiation boiler was anticipated before start-up. This is the reason for using replaceable boiler panels at the bottom of the vertical boiler. A protective flame spray coating was also afiplied. The coating failed after a few months and it became necessary to apply an Inconel 625 weld overlay. This ovo-lay now covers 160 m of the boiler surface and appears to be working well.
