Improving the resistance to carburising of creep-resistant castings

Piekarski B.

Archives of Foundry Engineering

2008

Vol. 8, iss. 4

181-184

The study presents the results of own investigations and of the investigations described in technical literature regarding various methods of improving the resistance to carburising of the creep-resistant structural parts of carburising furnaces. Most of the studies referred to were carried out in a Foundry of the Szczecin University of Technology. The results of the investigations on the effect of chemical composition of austenitic cast steel on its resistance to the carburising effect controlled through application of the anti-carburising coatings based on aluminium and constituted on high-alloy steel substrate were summarised. The possibility to use machining of castings as a means to raise their performance life in carburising atmosphere was also mentioned.
