One of the cost-effective methods to increase the Al content on the alloy surface is aluminising pack cementation. This method has been applied to steels [14,15,16], stainless steels [17,18], nickel and nickel-based alloys [19,20,21,22,23].Wang et al. [] has recently developed the aluminide-coated spheroidal cast iron and investigated its high temperature oxidation behaviour in air.

Multilayered Coatings for High-Temperature Steam …

10/7/2018· The aim of the study was to obtain a preliminary data focused on the steam oxidation performance of multilayered coatings deposited on 310 stainless steel and 800H Incoloy. The coatings were obtained through the aluminizing thermal diffusion technology with the formation of aluminides; some coating options had an additional top layer of selected composition. In this study, five different
