Metal Doctor is an electro-spark surface deposition and hardening (coating) machine using arc spark effect in the air.
The temperature of the spark point is approximately 25,000℃ however no heat accumulation occurs during diffusion and deposition periods. Alloy deposits on the surface without changing the property and demensions of base meterial. Also it creates strong metallurgical bonding that never be separated from workpiece.
Advantages
1. Easy to carry around and easy to operate
The product can be easily handled and applied on the spot, in comparison with the existing surface treatment equipments. (Size of 350 x 360 x 220 mm, weight of 13kg) The user can use it with general 220V power.
2. Preciseness
Coating can be exquisitely adjusted.
3. Low heat input
No contortion, modified-size, residual stress on the original meterial.
4. Tailorability
It allows the user to solve various kinds of die steel matters by repairing minute section, sensitive part of heat input, parting line to prevent defects of burrs.
5. Energy saving effect
It only needs 1.3kw of power consumption Free of pre-, post- heat treatments cost.
