The cast iron had been cleaned by the fused-salt method described in the section “Cleaning and Fixturing Procedures.” In Fig. 1 , note the clean line at the interface of the steel, versus the irregular shape of the cast iron interface. This is caused by the cleaning process, which removes surface...
