In the cold spray method, a coating is formed by exposing a substrate to high-velocity solid-phase particles, which have been accelerated by supersonic gas flow at a temperature much lower than the melting temperature of the feedstock."Development of the Coating Technology (process and materials) " for high function of the machine materialThe composite (cermet) coating of the ceramic and metal superior by abrasion properties-resistant had been developed by high velocity flame (HVAF) spray.The graduates are working actively at car, ship-building, precision instrument, and medical equipment manufacturers. Many of them choose to work in the fields that are not directly related to their thesis works, but they have the ability to adjust themselves to different environments as well as the basic scholastic ability.The copper particle collided on steel substrate at 500m/s: A copper part spouts out into a fold (called “ material jet ”) form the interface with the substrate. ⇒9
