Способ обработки стальных изделий, включающий азотирование в тлеющем разряде деталей, на которых имеются участки, где требуется различная глубина упрочненного слоя, для осуществления которого азотирование проводят путем вакуумного нагрева деталей в плазме азота повышенной плотности, формируемой между поверхностями детали и перфорированными экранами, тем самым реализуя эффект полого катода, отличающийся тем, что в зависимости от требуемой глубины упрочненного слоя плотность плазмы регулируют путем изменения параметров перфорированного экрана, таких как: ширина отверстий, расстояние между отверстиями, расстояние от экрана до поверхности детали.A method of processing steel products, including nitriding in a glow discharge of parts in which there are sections where a different depth of the hardened layer is required, for which nitriding is carried out by vacuum heating the parts in high density nitrogen plasma formed between the surfaces of the part and perforated screens, thereby realizing hollow cathode effect, characterized in that, depending on the required depth of the hardened layer, the plasma density is controlled by changing the parameters of the perforated th screen, such as the width of the holes, the distance between the holes, the distance from the screen to the workpiece surface.
