Key Applications of Supersonic Flame Spraying in Industrial Manufacturing

Overview of Supersonic Flame Spraying

Supersonic flame spraying is an advanced thermal spraying technique where coating materials are accelerated to supersonic speeds before impacting a substrate. This results in a dense, well-adhered coating that enhances surface properties such as wear resistance, corrosion resistance, and thermal protection. The process is widely adopted in industrial manufacturing for its precision and efficiency in coating critical components.
