Abstract

1396898 Coating with aluminium alloy by hot-dipping TOYO KOGYO CO Ltd 10 Nov 1972 52020/72 Heading C7F A ferrous substrate is coated with Al - 1 to 10% Cr alloy by hot-dipping, for 30 to 300 seconds in a bath at 750 to 950‹C, and then heating the coated substrate to 700 to 930‹C for at least 30 minutes. The coating may be given a secondary heat treatment at 950 to 1350‹C in an oxidizing atmosphere for 30 minutes to 10 hours.
