Preparation of Al/SiO2 Composite Coatings on the Surface of Aluminum Alloy through Atmospheric Plasma Spraying

In this work, Al/SiO2 composite coatings were deposited on the surface of aluminum alloy through atmospheric plasma spray. The effects of SiO2 volume in Al/SiO2 composite powders on the deposition behavior were investigated. It was found that the deposition of the Al/SiO2 composite powder became more difficult through plasma spray with the increasing of SiO2 contents. There were reactions between aluminium and silicon oxide during the deposition of Al/SiO2 powders in the plasma flame. The reactions were helpful to interface cohesions between aluminium and silicon oxide. Al/SiO2(60:40, 80:20) composites were more suitable for deposition and well interface cohesion through atmospheric plasma spray.
