HVOF SPRAY SYSTEM

HVOF is an acronym for H (High), V (Velocity), O (Oxygen), and F (Fuel), and means high velocity flame spray system.

HVOF SYSTEM

MJP-5000型

MODEL: MJP-5000 HVOF SPRAY SYSTEM

HVOF spray system produces supersonic jet flame of 5,000 feet per second (1,500 m/s), and the sprayed powder produces extremely high bond strength and near-zero porosity-free coating.
The HVOF spray system produces a particularly excellent coating for WC-based and CrC-based cermet spraying.

HVOF Coating
Example of Tungsten Carbide (WC/Co12) Coating Performance
Bond Strength (Mild steel) > 70MPa
Coating Hardness 1,100 ~ 1,300HV (300)
Coating Oxidation Rate < 3%
Coating Porosity < 1%
