Black Lake has partnered with Castling Eutectic, a worldwide leader of repair and wear protection, to offer the only thermal spray high-velocity oxy-fuel (HVOF) coating services in Iraq.
We are now able to provide HVOF spraying, using the most sophisticated plant and equipment; advanced robotic work handling and specialist diamond grind finishing techniques. HVOF coatings solve many severe surface attack problems caused by the effects of abrasion, erosion, corrosion, wear and high temperature environments and improve the lifetime of the equipment.
WHAT IS HVOF COATING?
HVOF coating is a thermal spray coating process in which the desired material in powder form is injected into the stream from a controlled feeder, where it gets heated and accelerated onto the surface by means of the high temperature, high velocity gas stream, producing a dense spray coating.
HVOF stands for High Velocity Oxygen Fuel. It is a flame spray process resulting in a mechanical bond between the feedstock of powder and the parent material. Heat is imparted into the very fine powder particles. The molten particles are then propelled at very high velocities to the prepared surface to be rebuilt. Application rates are lower than arc spray but the density of an HVOF coating and its bond strength are both higher than arc spray.
The advantages of HVOF coatings include:
REPLACEMENT OF CHROME PLATING
HVOF Carbide Coatings have now become a permanent replacement for hazardous Hard Chrome Plating. A few advantages of HVOF coatings over Hard Chrome plating are as follows:
