When dealing with voltages greater than 800V, these particles are iron nitride (, ? a small amount) and a small amount of oxides, and as the voltage increases, the increase, ?, and FeO decrease in the amount of 300020001000O 600 050 004 000 when the voltage up to 1000V, there is almost no oxide particles. 3 Analysis and discussion of treatment in nitrogen atmosphere,<a href="http://www.stivaliuggitalia.org" target="_blank" class="postlink">stivali ugg</a>, ASPN, the nitrogen atom is produced by the dissociation of nitrogen molecules from the: N Plant N, Nz + --* N + + N, the second step produced a reactive nitrogen atom.

Pg ·, XRDpatterns0tth. particlesdepositedoncopperplate at 49eV collision of N2 + molecular nitrogen dissociation of nitrogen molecules can enable the production of reactive nitrogen atoms 4 Conclusion N 『81 shows that the literature. Discharge. Electricity. When down in the 600v, N + in a process where the average obtained () voltage is low, the oxygen on the active screen plasma nitriding of the electric field energy is less than 49ev, space plasma reactive nitrogen is very small. Did not have a major impact,<a href="http://www.airjordansshoescheapnike.com" target="_blank" class="postlink">air jordans</a>, iron combines with oxygen to produce mainly a large amount of nitrogen oxide ion nitriding, so little effect nitriding. Discharge voltage high-speed rail can not be active screen plasma nitriding treatment. When at 800V, N + in a process where the average obtained from the south of electric (2) discharge voltage higher than 800V, the iron and nitrogen binding energy field for 75.22ev, more than 49ev, crack force by strong collision mainly generated when the activity of iron nitride Screen Plasma Nitriding Solutions produce large amounts of reactive nitrogen atoms. These high-energy nitrogen atoms in the live treatment, and to get a good nitriding effect. Of the screen near the iron atoms into FeIN, active screen is nitrogen.
