Role of nitriding layer

Various coated and non-coated steels are used in mechanical engineering for manufacturing friction pairs. In particular, parts with high hardness of interacting surfaces are used in open friction pairs (e.g. gears, reducers of hoisting devices , etc.). In closed friction pairs (friction bearings , etc.), one of the contact surfaces usually has a lower hardness. It is necessary for accelerated running-in, in the contact zone, during which the smoothing of surface macro surface roughness occurs and the optimal value of their roughness is formed, which provides sufficient wear resistance of the friction pair.

Machine tool engineering

In enclosed gears (e.g., machine tool drives and press equipment) it is desirable to concentrate the friction and tribological processes in a thin surface layer, which has a constant strength under cyclic loading conditions. At the same time it is necessary to provide surface protection with oxide films, which absorb most of the operating loads.

Properties of nitriding layer

Nitriding of structural alloy steels changes their following characteristics:

Resistance to fatigue failure.

Nitriding gives rise to residual compressive stresses that reach 350-400 MPa in the thin near-surface layers. They increase the strength of the product, which is operated under cyclic loading. At the same time the danger of formation and development of microcracks is reduced.

Contact endurance

The contact endurance is increased by the formation of a martensitic structure in nitrided steels. The distribution of stresses occurring during operation is such that the greatest values of contact loads occur not on the surface, but at a certain depth below it. The high level of contact endurance of parts surface is determined by chemical heat treatment, when a zone of nitrogen-containing martensite is created in the subsurface layers of steel;

Corrosion resistance

Metal nitrides are considerably more resistant to oxidation than conventional metals and steels. Their corrosion resistance lasts up to t° 500...550°C and in an atmosphere with high humidity. To achieve a greater effect, nitriding of structural alloy steels is often performed in multiphase systems where complex nitride coatings are formed;

Heat resistance

Resistance to plastic deformation at elevated temperatures is provided by the internal nitriding zone. The zone of recrystallization processes is shifted to 240 ... 280 ° C, which increases the stability of nitrides, thereby increasing the creep limit.
