It takes a very long time, and uncontrollable；This problem greatly reduces the speed of glow discharge nitriding, extends the production cycle.
When anode and cathode spacing is larger, cathode fall is lower, and ion institute band energy is lower, and current density is smaller, and ion bangs
Hit intensity is lower, therefore workpiece surface temperature is lower；When anode and cathode spacing is smaller, cathode fall is higher, ion institute band energy compared with
Height, current density is larger, and ion bombardment flux is higher, and workpiece surface temperature is higher at this time, therefore anode and cathode spacing is to glow discharge nitriding
It also have a large impact on, but traditional Ion Nitriding Equipment unreasonable structure, anode and cathode spacing is non-adjustable, so as to cause infiltration layer
Thickness and performance it is inhomogenous.
Gas nitriding and salt bath nitriding can generate harmful substance, pollute air.In contrast, though glow discharge nitriding can subtract
Light pollution, but there are still pollution problems.Ammonia used in glow discharge nitriding can interfere brain cell energetic supersession and change neurotransmitter,
There is inhibiting effect to cell, if will cause acute poisoning containing certain density ammonia in air or lead to malignant disease, such as
The edema of the larynx, cataract, conjunctivitis, is even blinded at pulmonary edema.Therefore, the ammonia pollution problem of glow discharge nitriding needs thoroughly to solve.
