Abstract

Die Erfindung betrifft Härteschutzmassen auf Basis von Borglas bildenden Substanzen für das partielle Aufkohlen von metallischen Bauteilen, die als Zusatz Magnesium-Silicium-Verbindungen enthalten.The invention relates to hard coatings based on boron-glass-forming substances for the partial carburizing of metallic components containing as an additive magnesium-silicon compounds.

Diese Härteschutzmassen können sehr vorteilhaft in Verfahren zum partiellen Aufkohlen von metallischen Bauteilen verwendet werden und eignen sich insbesondere vorzüglich für die Vakuumaufkohlung.These hardness protection compounds can be used very advantageously in processes for partially carburizing metallic components and are particularly suitable for vacuum carburization.
