Coatings Provide Protection from:
Wear & Abrasion
The Cobalt and Tungsten Carbide particles in fused
coatings offer excellent resistance to wear and abrasion.
The metallurgical bond ensures a high hot hardness and
high resistance to impact damage
Fusion produces very dense coatings that show no
porosity and therefore they produce excellent resistance to corrosion
These coatings are applied using the oxygen/gas powder gun. Once the
required depth of coating has been applied the coating is then fused to
the substrate material with a gas torch.
Typical fusing temperatures are around 1040-1120°C.
At this temperature the coating melts partially and so reacts with the
base material to form a very strong metallurgical bond (comparable with
some types of welding).
The coatings range in hardness from Rc30 to Rc65
Irregular shaped components such as pump bodies and rotors can be fused
in a vacuum oven. The increased control of the heating and cooling process
produces excellent pore free coatings which require a minimum of machining
to achieve finished sizes.
Rebuilding worn bearing and seal areas rather than scrapping
shafts can enhance the component’s service life and reduce maintenance
cost and downtime.
This cost effectiveness of this coating method has achieved wide
recognition in the food, chemical, mining and mechanical engineering
