Abstract:Our group has recently developed a non-contact direct-write print tool suitable for the top metallization layer on solar cells. This tool, termed Micro Cold Spray (MCS) allows for the direct deposition of metal powders onto a substrate forming a near-bulk property feature without post-processing. The development of this tool was facilitated by our experience with aerosol micro focusing in systems such as Aerosol Jet and Collimated Aerosol Beam Direct-Write (CAB-DW). In this paper we will present our results of… Show more
“…In contrast to coatings in which the modifying phase was crystalline ceramics (e.g. Al 2 O 3 and SiC), which also bounding during the application process, but due to the larger particle size caused tamping and stronger strengthening of the metallic matrix [13,14].

“…The use of the low-pressure cold spray (LPCS) method for spraying functional coatings is widely described in the literature [11][12][13][14][15]. This method allows the chemical composition of coatings to be controlled and high-class coatings to be obtained [16].…”
Scientific research shows that copper, under appropriate conditions, has the properties of an antibacterial substance and acts as a bactericidal and bacteriostatic material. Another material that has antibacterial properties is titanium dioxide (TiO2). Avoidance of a crystal structure allows the formation of coatings with nanometric TiO2 powders using the low-pressure cold spray method. The paper presents results of qualitative X-ray diffraction phase analysis and research using the methods of transmission electron microscopy of composite Cu–TiO2 coatings, with different proportions of the modifying phase TiO2. Studies have shown that the conditions accompanying application in a cold gas environment do not initiate conversion from the amorphous phase into the crystalline structure of anatase.

“…Ударная консолидация высокоскоростных твердых частиц позволяет получать холодное напыление (температура порошка и подложки гораздо ниже температуры спекания порошка) с высокой прочностью, низкой пористостью и минимальным или сжимающим остаточным напряжением. Использование газодинамической фокусировки позволяет поднять пространственное разрешение для металлов выше получаемого методами SLM и EBM [19][20][21].…”
