Archivio Istituzionale della RicercaThe purpose of this work is to illustrate the results obtained with a new thermochemical cycle where the gaseous nitrocarburization is followed by oxidation in a salt bath containing alkaline nitrates. By means of this treatment layers with a remarkable corrosion resistance are obtainable. It has been noted that the porosity of the gas-nitrocarburized layers is lower than that obtained by means of salt bath nitrocarburizing and the oxidation produced by nitrate baths has a good penetration power which is higher than that obtained with air oxidation. The influence of different degrees of superficial polishing before nitrocarburizing and oxidizing have also been studied.

Abstract
The purpose of this work is to illustrate the results obtained with a new thermochemical cycle where the gaseous nitrocarburization is followed by oxidation in a salt bath containing alkaline nitrates. By means of this treatment layers with a remarkable corrosion resistance are obtainable. It has been noted that the porosity of the gas-nitrocarburized layers is lower than that obtained by means of salt bath nitrocarburizing and the oxidation produced by nitrate baths has a good penetration power which is higher than that obtained with air oxidation. The influence of different degrees of superficial polishing before nitrocarburizing and oxidizing have also been studied.
