Coating of a lignin-based polymer with ceramic micropowders

This paper examines the behavior of Arboblend V2 Nature biopolymer samples coated with three distinct ceramic powders: Amdry 6420 (Cr2O3), Metco 143 (ZrO2 18TiO2 10Y2O3), and Metco 136F (Cr2O3-xSiO2-yTiO2). Atmospheric Plasma Spray (APS) method were used to deposit the coating onto the polymeric sub...

Summary:This paper examines the behavior of Arboblend V2 Nature biopolymer samples coated with three distinct ceramic powders: Amdry 6420 (Cr2O3), Metco 143 (ZrO2 18TiO2 10Y2O3), and Metco 136F (Cr2O3-xSiO2-yTiO2). Atmospheric Plasma Spray (APS) method were used to deposit the coating onto the polymeric substrate, which was obtained by injection molding. Several characteristics of the coated samples, as thermal behavior, roughness, as well as structural and morphological aspects, were evaluated during the investigation. The surface analysis of the samples demonstrated a uniform deposition for the ZrO2 18TiO3 10Y2O3 layer, but a less uniform deposition for the coatings containing ceramic micro-particles of chromium (III) oxides. The thermal research revealed the material's structural resilience. Regarding Atomic Force Microscopy examination, it highlighted the roughness of the coated surfaces and also the good adhesion of the microparticles on the biopolymer substrate.
