Mechanical part with a nanostructured TIO2-CR2O3 ceramic coating and method for depositing a nanostructured TIO2-CR2O3 ceramic coating on a substrate

摘要

#$%^&*AU2014202661B220190704.pdf#####ABSTRACT There is provided a method for depositing a TiO 2 -Cr203 ceramic coating on a substrate. The method includes mixing a powder of sprayable nanostructured titanium(IV) oxide (n-TiO2) and a powder of chromium(Ill) oxide (Cr203 ), thereby obtaining a n-TiO2 -Cr2 03 powder blend. The method also includes thermal spraying particles of the n-TiO2-Cr 2 03 powder blend on the substrate at an inflight particle temperature greater than 23500C and a particle in-flight velocity greater than 350 m/s, thereby obtaining a coated substrate. 2510/17 C C-) 00 0 C) ((WN)/Eww) 04eJJeGM
