Best Solution for Preventive Maintenance and Over Repairing of Machine Parts, Mold and Dies Depo Series are a newer Coating and Overlay method applying EDM (Electrical Discharge Machining) principle. A Depo Series device discharges direct current charged in the capacitor inside the main unit for a very short time of 10-6 to 10-5 seconds with a period of 10-3 to 10-1 seconds. This heats the portion of the electrode material that is in contact with the workpiece to 8,000 to 25,000℃. Then, the heated electrode material turns into plasma and metallurgically transfers to the workpiece surface. Next, the electrode material alloys with the surface, accumulates on it, and then spreads and enters under the surface, resulting in strong bonding Low Heat Input by adequate heat diffusion time No occurring distortion, shrinkage, pin-holes, or stress The Spark time is extremely short compared with the interval time so that no heat accumulation occurs during diffusion and deposition periods. Extremely Strong Bonding by Solid Diffusion Layer No removing after the process Electrode Material is deposited and alloyed to work surface forming a diffusion layer with penetration like grown roots. This provides Strong Boding Coating and Overlay deposition without removing. Shield Gas (Argon Gas etc.) prevents oxidation during processing, makes excellent quality Coating / Overlay possible. Applicable Substrates - Low and Medium carbon steels, Tool steels, Die and Mold steels, Cast steels, Stainless steels, Aluminum alloys, Copper alloys and the majority of alloys and composites having sufficient electrical conductivity
