摘要： A method for heat treating a steel component. The steel component is disposed in a heat treating furnace. The steel component is then exposed to a nitriding atmosphere at a predetermined nitriding temperature for a predetermined nitriding time interval. The nitriding atmosphere has a predetermined composition. The composition of the nitriding atmosphere is controlled while the steel component is exposed thereto. The steel component is slowly cooled to ambient temperature and then removed from the heat treating furnace. The heat treated steel component has substantially increased corrosion and wear resistance compared to the steel component prior the heat treating.
