Selected properties of Ti coatings deposited on ceramic AIN substrates by thermal spraying

摘要

This paper presents the results of an investigation of selected properties of Ti coatings deposited onto ceramic AIN substrates obtained by the detonation spraying method. It discusses and illustrates the microstructure of the coatings and joints among Ti coatings and AIN substrates. The results of linear distribution of Ti and Al in the cross section of the joint are also included, together with the stereometric patterns of the surface structure of Ti coatings deposited on AIN ceramic substrates. Finally, an finite element method modelling analysis of thermal residual stresses in the discussed coatings is presented.
