...With nitriding, the composition of the surface layer is modified by incorporating nitrogen, thereby increasing the surface hardness (700-1200 HV) as well as its resistance to wear and corrosion. The hardness is achieved through the formation of nitrides with the alloying elements of the steel, mainly Cr, Mo, etc. The thickness of the nitrided layer generally varies between 0.20 and 0.70 mm; the...

...THE PREFERRED METHOD FOR SLIDING AND ROLLING PAIRS SUCH AS PISTONS OR GEAR COMPONENTS. As early as 1930, initial attempts were made to nitride steel parts using a strong glow discharge in a nitrogen vacuum. Ionized gases are "shot" onto the workpieces to be hardened. This is still how the process works today. However, it was only with microprocessor technology that precise control of nitriding in...

...The nitriding hardening in vacuum using ion bombardment in the plasma of a modified gas discharge is a process for surface treatment of workpieces made of, for example, iron, steel, or cast iron. In a retort, a direct current is applied between the workpiece surface and the retort wall, with the workpieces primarily configured as the cathode and the retort wall as the anode. The atmospheric pressure is evacuated, and at a constant low-pressure range, the gas discharge is initiated in a reactive treatment gas by applying a base voltage.

...The heating of the parts, in a Cold-Wall plasma nitriding installation, is carried out only by pulsed plasma created in the vacuum chamber.
