Abstract
The process consists in immersing the articles which have previously undergone a thermochemical diffusion of either nitriding or sulphonitriding or carbonitriding type, in a bath of molten salts made up of alkali metal carbonates, nitrates, hydroxides and their oxygenated salts, the relative anionic weight quantities of carbonates, nitrates and hydroxides, expressed for sodium salts and corresponding to the active, that is to say liquid, phase of the bath being the following: 11 < CO<2-> < 23 19 < NO3<-> < 37 6 < OH<-> < 19 while the weight quantity of oxygenated salts of alkali metals, expressed as Cr2O7<2-> equivalent, is the following: 0.05 < oxygenated anions < 0.5. This process makes it possible to guarantee a high degree of reproducibility of the results, whatever the type of articles treated.
