Rutile phase is widely used in microelectronic, tribological applications and in the conversion of solar energy. Anatase phase is used in self-cleaning, antifogging, photo-catalytic and biomedical technologies. This work focuses on studying the required process conditions to obtain TiO2 targets by APS onto metallic substrates using commercial TiO2 powders (Oerlikon Metco in Switzerland) with suitable physical and chemical properties for technological and medical applications as PAPVD coatings. APS targets were compared to sintered ones. The raw powders were characterized by laser diffraction, SEM, XRF and XRD while the characteristics of the APS-deposited targets as well as the sintered ones were determined by SEM and XRD to identify the constituent phases. This work allowed confirming the advantages and limitations of both processes in terms of grain size, chemical composition, microstructural homogeneity and density in order to choose the best option to manufacture targets for PAPVD coatings for technological and medical applications. © 2018 ASM International® All rights reserved.engASM Internationalinfo:eu-repo/semantics/conferencePaperCoatingsMedical applicationsMicroelectronicsOxide mineralsPhase shiftersPowdersSinteringSolar energySubstratesX ray diffractionBiomedical technologiesChemical compositionsCrystalline systemsMetallic substrateMicrostructural homogeneityPhysical and chemical propertiesTitanium dioxides (TiO2)Tribological applicationsTitanium dioxide2021-03-23Jaramillo Raquejo D.Palacio C.C.Ageorges H.
