PVD Coating Furnace

All special steels must be hardened and tempered before being coated.

The tempering temperature must be high enough to gurantee structural stability at the coating. The tempering temperature is usually at 500°C and above

Advantages

• Superior Hard Coating
  The high ionization ratio of the AIP process provides coating with superior density and good crystallization.
• Maximum Adhesion
  In the AIP process with a high ionization ratio, metal ion bombardment is possible, resulting in coating with superior adhesion
• Low Processing Temperature
  Deposition of coatings at temperatures well below the annealing temperature of substrate removes the possibility of substrate distortion and the necessity to re-anneal after coating
• High Ionization Ratio
  A much higher ionization ratio (average 80%) than used in conventional ion plating allows the bias voltage to achieve a high ion bombardment effect and to produce highly-adhesive high-density film
