Cost analysis of various nitriding methods in vacuum furnace

1. The structure of the vacuum gas nitriding furnace is complex, the price is a little higher, and the operation is a little more difficult. However, the nitriding quality is good, which can reach a very deep layer and high hardness, but it takes a long time, and the amount of ammonia gas is also very high.

2. The production and manufacturing process requirements of plasma nitriding furnaces are very high, the materials used are also very exquisite, the electrical control technology content is very high, the overall requirements for operators are high, but the nitriding quality is the best, the infiltration speed is fast, and the nitriding cost is lower than that of gas nitriding, which is a good development trend.

3. The salt bath nitriding furnace has simple structure, low price, easy operation process and low nitriding cost, but the nitriding quality is not high and the waste is polluted, which is rarely used.
