Eight metals and alloys were wear-tested on autoclaved Zircaloy-2 as prospects for fuel element support-bearing surface materials. A 1.0 Cr-0.6% Mo steel showed the best results by wearing for distances up to 180 feet without scratching through the autoclaved Zircaloy-2 film. The results of these tests revealed that materials with high impact strengths and moderate hardness will give the desired wear characteristics with the autoclaved Zircaloy-2. Tests performed on Zircaloy-2 autoclaved for twelve days at 400 deg C ard 1500 psi showed no wear improvement is gained in this application by the longer autoclave cycle. (auth)
