The premature erosion of nozzle rings has been a commonly reported problem, creating unplanned down times and emergency service attendance.

Leveraging on High Velocity Oxygen Fuel (HVOF), Tru-Marine has launched its TM Supercoat method to offer significant protection to component erosion and wear.

  • Molten or semi-molten coating materials are sprayed onto the surface of the nozzle ring with a high-temperature- high-velocity gas stream
  • Resultant spray coating has exceptional hardness and outstanding adhesion to the substrate material, providing substantial wear resistance and improved corrosion protection due to less through porosity
  • Higher impact velocities and smaller powder sizes produce smoother as-sprayed surface, and the resulting dense spray coating can be ground to a very high surface finish
