Zusammenfassung:This manuscript highlights the behavior of a biodegradable polymer (Arboblend V2 Nature) coated with three distinct ceramic powders, Cr 2 O 3 –chromium oxide thermal spray powder, ZrO 2 18TiO 2 10Y 2 O 3 –zirconia–titania–yttria composite powder and Cr 2 O 3 -xSiO 2 -yTiO 2 –chromia–silica composite powder. The coated was realized on injected samples by using the Atmospheric Plasma Spray (APS) technique. The current investigation will explain the results related to the surface quality, micro-structure, morphology, mechanical, thermal and tribological properties. Thus, from a structural point of view the most uniform deposition was obtained in the case of composite powder based on zirconia. The thermal behavior of the samples coated with ceramic micro layers achieved stability up to temperatures slightly above 200 °C, pyrolysis taking place around 340 °C. The micro indentation, DMA, and scratch analysis responses were significantly influenced by the crystalline structure of the samples and the presence of the Cr 2 O 3 compound. Based on the increased characteristics of the coated samples the authors of the present paper consider that from parts made of biodegradable polymers and coated with ceramic micro-particles are appropriate for some applications that required harsh operating conditions.
