The stress-rupture test points are plotted in Figure 29.
Croloy 1-1 /4 comparison tests (2500 hr) in air and liquid metal
environment indicate that the liquid metal environment does not harmfully
affect the rupture strength. There were no visible indications of corrosion
attack by the liquid bismuth fuel.
E. LIQUID METAL CONTROL ROD CORROSION
The 1000-hr tilting capsule corrosion tests on three container materials
and three liquid metals of high neutron capture cross section were completed.
These screening test results indicate three satisfactory combinations of
container material and liquid metal, three unsatisfactory combinations, two
questionable combinations, and one combination that could not be properly eval-
uated because of test-difficulties. The three satisfactory combinations and
the two questionable combinations show enough promise to warrant additional
testing under simulated reactor operating conditions. Tests results are
condensed in Table V.
F. MOLYBDENUM COATING ON CROLOY 2-1/4
An electroless coating has been developed for the plating of Croloy 2-1/4.
The developed coating is 1 to 2 thick and contains mostly molybdenum oxide
(MoO2). A metallic sulfide and iron oxide are also present in the coating.
The electroless molybdenum oxide coating forms by simple contact of
Croloy 2-1/4 with the plating solution. The oxide coating is nonreducible to
metal, nonporous and crack-free. The coating seems adequately adherent
since it withstood the following thermal cycling test:
750-1000 F, 1 min up, 2 to 4 min down, 100 cycles
1000-2000 F, 1 min up, 2 to 4 min down, 25 cycles
Croloy 2-1/4 specimens coated by the electroless method are being
tested in the LMFRE fuel solution in tilting capsules. This test will determine
the corrosion resistance of the coating. The outcome of this test will
probably determine if any further coating research and development work is
to be attempted.- 76 -
