Unique Advantages
  • Increase in wear resistance by several times, superior to other coating techniques currently available in Indian market.
  • Dense microstructure (0.1-1% porosity)
  • Smooth surface finish (1-4um Ra). Much smoother finishes could be obtained by post-coating grinding
  • Extremely high coating band strength (>10,000 psi)
  • Very low substrate temperatures
  • Anti corrosion properties of ceramic and carbide coatings
  • Superior impact/fretting/erosion wear resistance
  • Ability to rebuild and repair of the coated parts
  • Inexpensive way to obtain required parameters of wear resistance in comparison to sintered parts made of wear resistance materials
  • Negligible thermal degradation of power during coating process makes the process suitable, not only for spraying reactive powders but also to preserve the bulk micro structures.

D-Gun Coatings

Following are some of the powders that can be used for Electro Spark Coating System by spray process which almost covers the entire spectrum of wear, erosion and corrosion related problems. The coating hardness, operating temperature and their respective fields of application are also given. However, a wide range of other powders can also be coated according to customer application requirement.
