Abstract
PURPOSE:To form the aluminum film of superior corrosion resistance free from voids and cracks by dipping a steel material in a molten Al bath containing 4wt% or under of iron then force-cooling the material with air, inert gas, etc. in the atmosphere. CONSTITUTION:After a steel plate is dipped in a molten Al bath containing 4wt% or under of iron (above 4%, adequate plating is difficult owing to the rise of melting point), it is taken out into the atmosphere and is blown with air or inert gas under pressures of 3 to 10 kg/cm<2> by using a compressor or the like, whereby it is force-cooled. It is desirable that the rate of cooling be from fan air cooling to about water cooling. This method effectively prevents crystallization of FeAl3 (theta phase) which degrades the characteristic of the film and forms the surface treating layer of the Al film intended for high temperature corrosion prevention, sea water corrosion prevention as well as for heat resistance, corrosion resistance, etc. of various steel materials.
