Ion nitriding of parts with deep holes, narrow slots, or blind cavities presents a well-known technical challenge: the hollow cathode effect. In continuous DC systems, electrons oscillate within the cavity, causing current density to build up and leading to localized overheating, non-uniform hardening, and arcing . Aputon’s 500kW Programmable DC Pulsed Power Supply overcomes this through its inherent pulsed characteristic. By periodically interrupting the applied voltage, the supply prevents the electron oscillation accumulation that drives the hollow cathode effect . The result? Effective nitriding of complex workpieces that would be impossible with DC systems – including deep bores of Φ4×80mm, narrow slots, and aluminum extrusion dies with cavities ≥0.6mm . Furthermore, the independent control of pulse frequency (0–5000Hz), duty cycle, and peak current allows process parameters to be tuned specifically for each part geometry, ensuring uniform case depth and hardness across the entire batch . At Aputon Electrical, we are driven by a passion to exceed expectations and enhance the operational capabilities of businesses worldwide. We believe in building long-lasting relationships with our clients by providing reliable, high-quality solutions that not only meet but anticipate their electrical needs, ensuring progress and sustainability for communities around the globe. Unlock the full potential of your nitriding furnace – even for your most complex parts – with Aputon’s 500kW pulsed power supply.
