Detonation Spray Coating Technology
Detonation spray coating (DSC) is a type of thermal spray technology that involves the formation of a plasma jet by the detonation of a fuel-oxidizer mixture. This plasma jet is then used to melt and vaporize a stream of feedstock material, which is then deposited onto a substrate to form a coating.
DSC is typically used to apply coatings of ceramics, metals, and other materials onto a variety of substrates. The process is known for its high deposition rates and ability to produce coatings with excellent adhesion, toughness, and wear resistance. It is often used in applications that require high-performance coatings, such as those in the aerospace, automotive, and energy industries.
