Abstract

A process and a plant are described for the anti oxidising surface treatment of steel parts that perform the steps of: washing or de greasing a charge of components; nitriding under gaseous phase the charge composed of the sub steps of: pre heating with nitrogen till a temperature of 350 °C; heating from 350 °C to 450 °C in an atmosphere composed of a mixture containing C02 and N2; heating from 450 °C to 520 600 °C for half an hour in an atmosphere containing N2; maintaining at the" same temperature of 520 600 °C for a period from 2 to 10 hours . in an atmosphere composed of a mixture containing NH3 and N2; washing with nitrogen the environment where said nitriding occurred; and steam oxidising consisting in the immission of overheated steam at a temperature in the range from 490 °C and 540 °C for the necessary time to obtain a complete oxigen iron exchange.
