<p>According to the invention, a coating with a thickness of between 0.1 and 0.3 mm is formed in one passage of a metallization device, whereby the ratio of through pores is no more than 6 - 8 %. The aluminum content of the coating material is at least 90 to 93 %. The bond resistance of the ingot surface is at least 30 to 50 MPa. The coating can be applied to the degreased and unturned surface of an ingot.</p> |
