Microstructure of plasma sprayed Al2O3-3wt%TiO2 coating using freeze granulated powder
Artikel i vetenskaplig tidskrift, 2016

This study is aiming at controlling the microstructure of plasma sprayed Al2O3-TiO2 composite coatings using freeze granulated powders. As sprayed and sintered Al2O3+3wt%TiO2 powders were air plasma spayed with industry process parameters and compared with a commercial powder. The resulting coatings were investigated with respect to powder flowability, porosity and microstructure of the granules. The results showed that microstructure and melting fraction in the coatings could be tailored with the freeze granulation process and heat treatment conditions.
