| titleOfInvention | PROCEDURE FOR TREATING PIECES OF IRON METAL IN ORDER TO IMPROVE THEIR CORROSION RESISTANCE |
| abstract | PROCEDURE FOR TREATMENT OF FERROUS METAL PIECES IN ORDER TO IMPROVE ITS RESISTANCE TO CORROSION. IT ESSENTIALLY CONSISTS IN SUBMERGING FERROUS METAL PARTS, WHICH HAVE UNDERGONE A THERMOCHEMICAL TREATMENT, ESPECIALLY NITRIDATION, ASSOCIATED OR NOT WITH CEMENTATION AND/OR SULFURIZATION, IN A KNOWN MOLTEN SALT BATH, TO WHICH HAS BEEN ADDED AN EFFECTIVE AMOUNT OF AT LEAST A HALOGENOPHOSPHATE ANSWERING ONE OF THE FORMULAS (I AND II) IN WHICH X AND XK ARE HALOGENS AND M IS A VALENCIA METAL M. THE PREFERRED HALOGENOPHOSPHATE IS SODIUM, POTASSIUM, CALCIUM OR ZINC MONOFLUOROPHOSPHATE. THE MOLTEN SALT BATH CAN BE OF THE OXIDIZING TYPE, FOR EXAMPLE, WITH A WEIGHT COMPOSITION OF KOH 65%, NANO3 25%, NA2CO3 10%, OR OF THE NEUTRAL TYPE, FOR EXAMPLE, A EUTECTIC BACL2 50%, CACL2 30%, NACL2 twenty%. THE HALOGENOPHOSPHATE CAN BE ADDED IN THE DOSE OF 0.1 TO 20 G PER KG OF BATH OF SALTS. |
