<p>The method uses a flow of ammonia and provides for heating the articles up to a saturation temperature chosen within the range of 750-1050 °C, their isothermic exposure to that temperature and cooling at a rate of 500-700°/mn, after which the treated articles are subjected to repeat nitriding in the ammonia flow by heating up to a temperature chosen within the range of 500-600 °C, isothermic exposure to that temperature and subsequent cooling.</p> |
