HVOF COATINGS

Looking for the ultimate wear-resistant coating?

HVOF is your answer.

HVOF produces premium quality, dense coatings that exhibit high adhesion to the substrate. It boasts excellent wear resistance that extends component longevity and profitability. The HVOF process tends to be used for the application of high-value, high-performance coatings, such as tungsten carbide and cobalt superalloys.

A NEW METHOD

Initially, thermal spray technology centred around techniques of heating the particles into plasticity before impact to guarantee adequate deformation. HVOF introduced a new method.

HOW IT WORKS

We use a small combustion chamber to generate extreme exhaust velocities. Powdered material injected into this exhaust stream gains so much velocity that the force of the impact alone is virtually enough for adequate bonding. In fact, the kinetic energy of the particles is so great that most porosity typical in a traditionally-applied coating is essentially hammered out.

New Metal Surfaces has a 6-axis KUKA robot on a 7th-axis linear track to allow spray automation for most components. The higher velocities of the HVOF stream can remove typical masking materials, so customised hard-masking is often required.
