Description
Gegenstand des Hauptpatentes ist ein Verfahren zum Borieren von Metallen, insbesondere von Stahl, in borierenden Pulvern, bestehend aus einem borabgebenden Mittel sowie Aktivatoren und Streckmittel, wobei das Gemisch zusätzlich freien Kohlenstoff enthält.The main patent relates to a method for boronizing metals, in particular steel, in borating powders, consisting of a boron-releasing agent and activators and extenders, wherein the mixture additionally contains free carbon.
Im Hauptpatent ist angegeben, daß ein vorteilhafter Bereich für den Gehalt an freiem Kohlenstoff zwischen 2 und 40% liegtThe main patent states that an advantageous range for the free carbon content is between 2 and 40%
Es wurde nun gefunden, daß für den praktischen Einsatz der Bereich zwischen 8 und 40% besonders wertvoll ist. In diesem Bereich ergeben sich die günstigsten Eigenschaften der nach diesem Verfahren behandelten Werkstoffe.It has now been found that the range between 8 and 40% is particularly good for practical use is valuable. In this area, the most favorable properties result from this process treated materials.
