Abstract

<PICT:1073871/C6-C7/1> An aluminium coating thicker than 0.002 inch is formed on a steel base by preheating the steel base to a temperature within the range from substantially 500 DEG F. to 1200 DEG F., and passing the preheated steel base through a bath of molten Al under positive pressure head for a time interval sufficient to deposit on the steel base a solidified Al coating having a thickness greater than 0.002 inch, the time interval being too brief to permit significant remelting of the deposited Al coating within the bath. "Significant remelting" denotes any remelting that would reduce the thickness of the coating to less than 0.002 inch. The term "aluminium" includes aluminium alloys. Steel wire 11, as it is passed through apparatus as shown in Fig.1, is preheated at 10 and then coated with Al from a molten bath 15, ceramic members 30 and 24 having been moved axially apart to allow the molten Al to flow on to the wire Fig.2 (not shown). The arrangement is such that almost the complete thickness of the A1 coating solidifies on the steel wire in the first few millimetres of the wire's travel through the bath and the time of immersion is too brief to allow significant remelting of the deposited Al. Prior to coating, the wire may be subjected to a series of specified cleaning steps. It is then heated at 500-1200 DEG F. in an atmosphere of CO and/or H2. The lower is the preheating temperature and the lower is the coating bath temperature, the thicker is the coating of Al obtained. The wire, as it leaves the bath, passes through a N2 or A atmosphere to prevent oxidation. Depending on the temperature of preheating, an interfacial steel -Al alloy layer may be formed between the steel core and Al coating. Such alloy layer when formed is .0002 to .0007 inch thick and may or may not be continuous. It ensures adequate bonding of the Al to the steel so that the coated wire may be mechanically worked, e.g. in a drawing or rolling die. When no alloy interlayer is formed, the coated wire is heat treated prior to drawing. Electrical power cables may be made by the process.
