Abstract

Metals, esp. steel, are boron coated using a powdered mixt. of boron releasing cpd., activator and extender, as in parent patent, but using a free carbon content of 8-40% cf. 2-40% used in parent patent.

Description

Verfahren zum Borierten von Metallen, insbesondere von Stahl (Zusatz zum Patent .,.... . (Patentanmeldung P 21 26 379.6) Gegenstand des Ifauptpatentes ist ein Verfahren zum Borierten von Metallen, insbesondere von Stahl, in borierenden Pulvern, bestehend aus einem borabgebenden -Mittol sowie Aktivatoren und Streckmittel, wobei das Gemisch zusätzlich freien Kohlenstoff enthält. Process for boronizing metals, especially steel (add for patent., ..... (Patent application P 21 26 379.6) Subject of the main patent is a method for boronizing metals, especially steel, in boronizing Powders consisting of a boron-releasing agent as well as 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 % liegt.The 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 ffi besonders wertvoll ist.It has now been found that for practical use the area between 8 and 40 ffi is particularly valuable.

In diesem Bereich ergeben sich die günstigsten Eigenschaften der nach diesem Verfahren behandelten Werkstoffe.In this area, the most favorable properties of the after materials treated with this process.
