Coultas, T A

Static corrosion tests were made on several refractory materials in tin and bismuth at 1800 deg F. The materials tested in tin, listed in decreasing order of resistance to attack, were: graphite, Al/sub 2/O/sub 3/, Vycor, W, MoSi/ sub 2/, TaC, Kennametal K-l38A, Haynes Metaruic LT-l, Ta, and Mo. The materials tested in bismuth, with those most resistant to attack listed first, were: graphite, Al/sub 2/O/sub 3/, ZrO/sub 2/, ThO/sub 2/, Mullite, Vycor, TaC, MgO, MoSi/sub 2/, Re, W, Mo, K-138A, SiC, Ta, Metamic LT-l, Ir, and AISI type 303 stainless steel with Mo coating. In addition, some tests were made at higher (2600 to 3600 deg F) temperatures. Results were appraised by both visual and metallographic examinations and by chemical analysis of the residual liquid metals. A small, simple method of testing materials in circulating liquids to obtain evidence of mass transfer is described. (auth)
