Research Abstract

The adhesion strength of Al coatings formed by cold spray (CS) on ceramic substrates increased with a decrease in the spray angle. A low-density interface layer of thickness 50 - 100 nm was found and characterized at the interface between coldsprayed Al particles and a soda-lime glass substrate with transmission electron microscopy. The layer was composed of amorphous and nano-crystalline grains, and had a different chemical composition from Al and glass. The cold sprayed copper and aluminum coatings subjected to an ultrasonic impact treatment (UIT) has an affected zone of several tens of μm to several hundred of μm. Furthermore, nano-crystal structure was observed at 10 μm from surface in copper coating.
