Mackay’s have the following HVOF equipment, housed in 4 fully robotic spray cells:

  • 1 off Praxair JP 8000 spray system
  • 2 off Praxair JP 5000 spray systems
  • 1 off Praxair ST 4000 spray system
  • 1 off Sulzer Metco DJ 2700 hybrid
  • 1 off DJ 2700 internal attachment

THE PRAXAIR JP 5000:

The JP 5000 has been developed and refined to produce the absolute best possible coating quality.

High particle velocity was the primary design objective of the JP 5000, the basic rules for coating quality are:

  • High combustion pressure
  • High gas velocity
  • High particle velocity

A key benefit of the high particle velocities generated by the JP 5000 is the extremely high density and low oxide content of the coating, this is beneficial in corrosion and wear applications.

THE ADVANTAGES OF THE JP 5000’S COATINGS:

  • High density (low porosity)
  • Higher hardness
  • Better wear resistance
  • Higher bond strength
  • Improved corrosion resistance
  • Smoother as sprayed coatings
