Black Lake has partnered with Castolin 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.


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.


The advantages of HVOF coatings include:

  • HVOF coatings are very clean, hard, and dense with fine homogeneous structures
  • Coatings are tenaciously bonded to the substrate with a high degree of bond strength
  • HVOF coatings have low compressive stress, which results in very thick coatings
  • HVOF coatings are used to improve or restore a component’s surface properties or dimensions, thus extending equipment life


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:

  • They are more abrasive resistant than Hard Chrome Plating
  • They give better fatigue strength to the component
  • They provide equally good corrosion protection
