Abstract:

Beryllium diffused surfaces on Type 310 stainless steel, Inconel, and Haynes Stellite 31 were evaluated for resistance to fuel-oil-ash slags at elevated temperature. Considerable improvement in resistance to corrosion caused by vanadium bearing slags was induced in the stainless steel. However, a decreased resistance to sulfatechloride corrosion was shown by all surfaces, while the over-all resistance of the Haynes Stellite was significantly reduced by the berylliumizing process. A metallographic examination of the coatings is presented.
