Download ion proponents assert that a traditional gas nitriding furnace, even with automatic control, can consume up to 100 times more than an ion furnace. This, however, is incorrect with respect to the advanced Nitrex technology. A Nitrex furnace consumes a very similar amount of gas to what an ion one does for a comparable batch.

Advantages and Disadvantages of Nitriding : 1. Case-Depth: Salt-bath nitriding is commonly restricted to 4 hours, because the density of pores increases with time. Gas nitriding is not restricted but normally a practically reasonable time of 90- 98 hours is not exceeded. Thus, when greater-depth than that can be obtainable with salt-bath nitriding is required, gas-nitriding is done. (ion) nitriding and gas nitriding have various practical consequences. For example, gas nitriding increases the surface roughness of gray cast iron. Proper identification of the advantages and disadvantages of these two methods could significantly improve their use.

Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state. In this technique intense electric fields are used to Comparing gas nitriding and plasma nitriding, Anichkina et al., , verified that the growth rate of the diffusion layer for the ion nitriding of a low alloy steel is greater than that obtained by gas nitriding. Plasma nitriding is faster than conventional gas nitriding due to the different mechanisms of nitrogen introduction into the metal .

Nitriding does not change part weight, but they may grow a little—about 0.001-0.005 mm on a diameter of about 50 to 80 mm. Growth is predictable and repeatable. Thermochemical Treatment of Metals 77 2.1.3. Plasma (ion) nitriding Plasma nitriding, called also ion nitriding, was invented by Wehnheldt and Berghause in 1932 but became commercially viable as late as in 1970’s. It uses the glow discharge phenomenon to introduce nascent nitrogen to the surface of an alloy and its subsequent diffusion into

Many components are ion nitrided in a finished condition. Because nitriding is carried out at a temperature far lower than the phase transformation temperature, properly nitrided gears exhibit no distortion. An advantage of ion nitriding in these applications is the ease of protecting selective areas from hardening using mechanical masking [2]. Nitriding does not change part weight, but they may grow a little—about 0.001-0.005 mm on a diameter of about 50 to 80 mm. Growth is predictable and repeatable.
