Abstract
Aluminum powder of 99.85 wt.% purity has been sprayed onto three kinds of glass substrates by cold spray. An interface between Aluminum coating and all glass substrates were smooth, and the single aluminum particle adhered without a gap. It is not observed erosion damage of glass substrate by aluminum with lower impact velocity than critical velocity. In Aluminum coating and the neighborhood of interface of Soda-lime glass substrate, sodium included in glass substrate was distributed in high density. There might be the stratum that the element which constituted an aluminum coating and glass substrate scattered, and it was suggested that the solid-phase joining by a chemical reaction were initiated.
