Hypersonic Metallization, H.M

Hypersonic Metallization

HM is the most efficient thermal spraying method compared to previously known thermal spraying methods and can be applied to all areas such as wear resistance, corrosion resistance, and heat resistance.
The flame speed at the time of spraying is 1500m/sec and the transfer speed of particles is 500m/sec. HM is a spraying method that has both the advantages of Arc Spray and HVOF.
