Alloy developers worldwide have struggled to create creep-resistant alumina-forming, iron-based austenitic stainless steels for use as high-temperature structural alloys, but with limited success in balancing alloy cost, oxidation, and creep resistance. This article describes the research and development of a novel cast alumina-forming austenitic stainless steel. This work won the prestigious Engineering Materials Achievement Award presented at IMAT 2023 in Detroit.

Radio frequency inductively coupled plasma (RF-ICP) spraying is shown to be a promising method for producing oxidation-resistant W and W-Cr coatings on plasma-facing surfaces in fission and fusion reactors.

A high-velocity oxyfuel (HVOF) spray gun that operates on conventional (gas or kerosene) fuels as well as liquid-gas combinations is shown to be capable of producing MCrAlY bond coats consisting of a rough surface layer (for adhesion) on a dense base (for oxidation protection).

This article discusses the influence of water vapor on the performance of YSZ thermal barrier coatings, particularly the oxidation resistance of the bond coat.
