Product Feature

Features of   pulse Ion Nitriding Equipment:  1:process parameters are adjustable
one ofthe advantages ofpulsed powEr supply is that procEss parameters and physical parameters can be adjusted independently. under the condition ofDC Power supply, it is nccEssary to meet the requirements of the current density on the  surface of the part and the requirement of the insulation current ofthe part. The two affect each other and can not achieve the ideal parameters. The pulse current density is determinedby the peak current,  so the proc css parameters can be adjusted in a wide Iange.
2: Fast arcing speed
The output characteristics ofthe pulse powEr supply itselfhave the characteristics ofresisting the rapid development ofthe arc. Due to the extremely fast response speed ofthe IGBT switch, once the arc discharge is detected, the powEr supply can be turned off andre-ignited in a short time of tens ofmicroseconds

3:It is benefcial to thenitriding of deep holes and deep groovcs
when performing ion nit riding, hollow cathode effects often app car in the holes and grooves ofparts. The pulse power supply can quickly interrupt the accumulation of carriers to resist the hollow cathode effect and avoid local high temperature ofthe parts. The pulse power supply can be used at higher air pressure. under starting glow, when nit riding small and deep holes and groovES, the glow will not be extinguished due to high air PIes sure,  so as to ensure uniform nitriding ofholes and groovcs

4:energy saving
Due to the characteristics ofthyristor devices, when designing aDc power supply, it is ncc ess ary to design a current-limiting resistor to limit the rapid increase ofcurrent. cannot oscillate so that the aIC discharge cannot be controlled), under the condition of 150A full load output, the power loss is extremely large, and the resistance ofthe pulse resistance is about 0.1, which improves the comprehensive trafc and sav cs electricityby≥30%.

FAQ

1. What is the different about Nitriding furnace and Vaccum furnace?
 

Ion nitriding, also known as glow nitriding, is carried out using the principle of glow discharge. Ion nitriding is to use the metal workpiece as the cathode furnace body as the anode in a low-vacuum furnace filled with nitrogen gas. After being energized, the nitrogen and hydrogen atoms in the medium are ionized under the high-voltage DC electric field, forming a plasma region between the cathodes. to adsorption and diffusion, nitrogen penetrates into the surface of the workpiece.
Under the action of a strong electric field in the plasma area, the positive ions of nitrogen and hydrogen bombard the surface of the workpiece at a high speed. The high kinetic energy of ions is converted into thermal energy, heating the surface of the workpiece to the required temperature. Due to the bombardment of ions, atomic sputtering is generated on the surface of the workpiece, which is purified. At the same time, due to adsorption and diffusion, nitrogen penetrates into the surface of the
workpiece.
The gas nitriding system workpiece is placed in the furnace, and the NH3 gas is directly injected into the nitride furnace at 500 to 550ºC, which is maintained for 20 to 100 hours, so that NH3 gas is decomposed into atomic (N) gas and (H) gas for nitriding. The main purpose is to produce a wear-resistant and corrosion-resistant compound layer on the surface of the steel.

2. Precautions for ion nitriding

The cleaning workpiece is nitridized with gas, but it is best to dry or cool and then put it into the furnace to save arcing time. The workpiece should be evenly loaded into the furnace. The interval between the workpiece and the cathode and anode must be more than 30mm, so as to avoid the excessive current density between the two poles and the local temperature of the workpiece being too high. Do a good job of anti-seepage. Any hole less than 2mm must be shielded, and the sample must be placed in a position that can be consistent with the temperature of the workpiece.

3.What kind of work piece can be use with Nitriding furnace ?

4Cr5MoSiV1(H13),3Cr3Mo3W2V,5Cr4W5Mo2V ,20 steel,40 steel,20Cr,20CrMnTi,40Cr/38CrMoAl,42CrMo, 50CrV,,1Cr18Ni9Ti,40 steel,alloy structural steel, bearing steel, spring steel, die steel, tool steel and other materials.

4. What's the max temperature nitriding furnace working for ?

Normal steel working temperature around 520-550 degree,if the Titanium alloy heating temperature must be around 750-800 degrees,this is customized type,you can inquire our sales technical manage.
