Abstract
1309580 Sintered metal coatings NIPPON KOKAN K K 18 Nov 1970 [21 Nov 1969] 54767/70 Heading C7D Steel sheets are coated with a metal powder slurry containing one or more corrosion inhibiting compounds yielding molybdate, chromate or benzoate ions in a total concentration of 10<SP>-2</SP> to 10<SP>-5</SP> g ions/l of water; coating being followed by drying, rolling and heat treatment. As exemplified, steel sheet was coated with Al slurry and rolled to give 5-7% elongation and a coating weight of 75-80g/m<SP>2</SP> after drying. The slurry may contain Na NO 2 , Na 2 , MoO 4 or a mixture of C 6 H 5 COONa and Na 2 MoO 4 . The following heat treatments were employed; (i) an oxidising atmosphere at 600‹C for 2 min (ii) an oxidising atmosphere at 650‹C. for 30 sec., rolling, post-aging treatment, heating at 400‹C. in electric furnace and rolling for temper regulation, and (iii) induction heating to raise the surface temperature to 500‹C. after 2 mins.
