This work is a Copper oxide (CuO) thin films were effectively produced using cold spray technique. The process take place in an inert gas (helium) without using catalyst. Nano CuO was deposited on a glass slide, using helium as carrier gas heated to 100, 200, 300, and 400oC, respectively on heated glass substrates at 300°C. The effect of structural and electrical properties was examined at each temperature for each film. AFM images show that the CuO thin film have different diameters ranging from 80 to 600 nm, and low surface roughness about 20.9 nm. The measured value of copper oxide resistivity was found to be decrease very much with the increasing temperature. All the result showed that copper oxide is suitable material for photovoltaic applications. This research is part of a larger work for the solar cells industry. Therefore, the aim of this research is to study the electrical properties of solar cells in the primary stages of manufacturing from available materials at low costs.
W pracy opisano uproszczone modele erozyjnego zużycia czystych metali i powierzchni metalowych pokrytych tlenkami z uwzględnieniem podwyższonych temperatur. W części badawczej przedstawiono stanowisko badawcze i opisano metodykę pomiarów. Dokonano analizy wyników badań zużycia erozyjnego powłok katalizujących procesy dopalania CO i redukcji NOx, wytworzonych z mieszanin tlenków miedzi i chromu. Ustalono, iż odporność erozyjna powłok wzrasta z podwyższeniem udziału Cr2O3 w mieszaninie.

In this paper simplified models of high-temperature erosive wear of pure metals and metals covered with oxides are presented. The analysis of experimental results of corrosive wear of coatings made of copper and chromium oxide mixtures which catalyse combustion process of CO and reduction of NOx is described. It was stated that the erosive resistance grows with increasing amount of Cr2O3 in the mixture.
