Examples of applications are: Cylinders; Pistons; Gears; Crankshafts; Cams; Barrels; Nitriding and nitrocarburizing can replace surface treatments like chromizing or black oxidizing. These processes are most commonly used on high-carbon, low-alloy steels. Best Use Applications. Precision Nitriding for Your Critical Specs. The results of industrial applications of nitriding, developed by the Institute of Precision Mechanics are given.

Nitreg® nitriding with its precise control of surface concentration of nitrogen makes it possible to obtain reproducible properties of treated parts, and consequently improve tools performance.. Aerospace specifications often call for controlled nitriding with limited white layer capable of producing deep diffusion cases on Nitralloy 135M and other alloyed steels. Hence nitriding technologies focus on the source of nascent (atomic) nitrogen. [1] Therefore, nitriding is an important surface treatment for ferritic steels. Nitriding parameters are adjusted to the expected die duty cycle resulting in significant cost reductions and virtual elimination of unscheduled press shutdowns. Nitriding and plasma nitriding are processes that can increase the surface hardness of titanium alloys. R&D, design, production and quality control consolidated with many years of outstanding experience. Nitriding properties required for dies and other tooling are high wear resistance, impact strength, resistance to softening, and high dimensional stability. The reduction in white layer thickness eliminates the need for costly finishing operations that might otherwise have been required. The temperature range of thermocycling determines the character of the surface strengthening. Springs are routinely nitrided to enhance their fatigue resistance to premature failure.

The dies are vacuum hardened and tempered, flame hardened, flood-welded, and nitrided, as applicable, for better life. Shafts made of stainless steel or nickel based alloys require vacuum hardening and tempering, frequently followed by nitriding. Salt bath nitrocarburising Salt bath nitrocarburizing is carried out in gas or electrically heated crucible furnaces. The thickness of the layer enriched by nitrogen achieves 0.1 to 0.15 mm, its microhardness arrives to 700-900 MPa. Nitriding is a process of diffusing nitrogen atoms into the metal’s surface. However, their poor tribological behavior is a major drawback, and many surface engineering processes have been developed to enhance wear in titanium alloys such as nitriding. Nitrogen is plentiful on Earth, however, in nature it exists as a two-atom molecule, chemically inert and too large to penetrate the surface. A good example of such a part is the fuel injector, which requires a high wear resistant surface necessary to prevent abrasion by a high-velocity fuel stream. Properties of small shafts exposed to atmospheric conditions and/or other corrosive environments are frequently treated in an in-process post-nitriding oxidizing treatment. A good example of such a part is the fuel injector, which requires a high wear resistant surface necessary to prevent abrasion by a high-velocity fuel stream.
