The 0.08% and 1.0% Carbon steel plates were taken and dipped into the aluminum bath after flux treatments were carried out at 690°, 710°, 730° and 750°C of the aluminum bath temperature and immersion time, 5, 20 and 60 seconds respectively. The main result were summarized as follows,
(1) The range of the effected temperature was existent at 690°-730°.
(2) The excellent properties were obtained on the alloying layer of Fe-Al compound having 0.01-0.03mm
