Abstract
Vynález se týká způsobu nitridace součástí strojů, přístrojů a zařízeni, zahrnující ohřev na teplotu nasycení a prodlevu při této teplotě za spolupůsobeni magnetického pole. Podstata vynalezu spočívá v tom, žé prodleva probíhá ve zkříženém magnetickém stejnosměrném poli. Je tím dosaženo zintensivněni procesu nasycováni a zlepšení pracovních charakteristik.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for nitriding components of machines, apparatus and devices comprising heating to a saturation temperature and a dwell time at this temperature in conjunction with a magnetic field. The essence of the invention is that the delay occurs in a crossed magnetic DC field. This achieves an intensification of the process of saturation and improvement of the working characteristics.
