✦ Synopsis

The oxidation behaviour of Fe-23Cr-SAl-based alloys unmodified and modified by incorporation, using various procedures, of reactive elements and by implantation of sulphur was investigated at temperatures up to 1673 K, under both isothermal and thermal cycling conditions. The reactive elements, in general, slightly enhanced the oxidation rate of the studied alloy and improved the scale resistance to spalling, these effects being dependent on a few factors. Implanted sulphur did not exert significant influence under studied conditions.

## Abstract The effect of 0.6 wt.% yttrium addition on the oxidation behaviour of the coating material Ni‐23Co‐19Cr‐12Al was studied under isothermal and thermal cycling conditions in air at 1373 and 1473 K. The reaction was followed thermogravimetrically while the SEM, EDX, EPMA and X‐ray diffract
