Cold gas-dynamic supersonic powder spraying method (CSM) is a new method of coating deposition. Materials' Superficies Modifying, which aims to reinforce materials corrosion-proof, antifriction, strengthening, etc., has been regarded as one of the worldwide new high-technology focuses.
The distinguishing feature of CSM is the possibility to produce coatings under the jet temperature of 0-500, which is not high enough to melt particles. Consequently, avoiding the faulty caused by the h...
