Abstract

In this paper, industrially manufactured CCD cameras are tested in plasma or HVOF spray processes under correct production conditions. Typical spray systems often used in industry (plasma technology, Sulzer Metco, TAFA, CDS, Top Coat) are used. A wide range of powder mixtures is examined, such as aluminum oxide, aluminum titanium oxide, aluminum oxide-SiO, aluminum oxide-titanium dioxide-silicon dioxide-iron(I) oxide, WC-Co, zirconium dioxide, and yttrium oxide. A statistical evaluation of the recorded measured values of particle size, speed, and temperature is carried out, in order to determine the influence of the process parameters (arc current, gas flow throughput, oxygen and fuel throughput, powder throughput, and carrier gas throughput) with regard to the powder jet parameters. Paper includes a German-language abstract.
