Abstract Scope |
Cobalt alloys used in hard facing cladding layers accounts for the greatest proportion of gamma exposure in nuclear plant workers. Therefore, replacing the cobalt alloys in new designs is a priority. Unfortunately, replacement alloy systems that replicate the performance of cobalt-based alloys are not readily available. In this study we present structural integrity assessment conducted on PTA deposited nickel-base hard facing alloys, highlighting some of the difficulties in replacing cobalt alloys with nickel alloys, namely cracking and residual stress formation. |
