This work deals with a study of properties of layers prepared by a simple, cheap, and efficient method of siliconizing from liquid phase. They were prepared using the melts AlSi20 and AlSi28 (wt.%); their high silicon content provides for almost a tw

The basic type of MnCr steels (composition 0.05Mn19Cr13) was found to be highly resistant to chlorides. Additions of titanium, niobium and vanadium did not impair resistance to stress corrosion cracking, but addition of nickel in excess of 0.5% appre

This paper is concerned with a potentiodynamic polarization method based on reactivation from passive state. The suggested test method was verified on austenitic chrome-nickel and chrome-nickel-molybdenum steels with a stepped-up carbon content. For

Die Spannungskorrosionsprufung in MgCl2 und CaCl2 zeigt, das die klassischen austenitischen CrNi- und CrMnNiN-Stahle gegen diese Korrosionsart nicht ausreichend bestandig sind. Gut bestandig sind hingegen auch in heisen Losungen die MnCr-Stahle. Die

Aus den Ergebnissen von Untersuchungen zur Spannungsriskorrosion von austenitisch-ferritischen MnCr-Stahlen (19–22 Mn, 13–18 Cr, Zusatze von Mo, V, Nb, Ti, N, B) lassen sich die folgenden Schlusse ziehen: Stickstoff verringert die Bestandigkeit g
