Claims (1)

  1. Способ низкотемпературного азотирования сталей, заключающийся в поверхностном легировании стальных деталей нитридообразующими элементами с помощью лазерного нагрева и последующем азотировании в печи в среде аммиака при температуре Т= 540°С, отличающийся тем, что азотирование проводят в течение 27 ч, затем подачу аммиака прекращают и выдерживают детали при той же температуре в течение 60-120 мин.
