The interfacial transfer of aluminium to steels and ceramic materials under loaded contact at high temperatures II: Both surfaces at high temperatures

The rolling contact between aluminium strips and rolls of different materials, in which the rolls were heated in situ with an auxiliary furnace to a temperature similar to that of the strips, was studied.

Description
Summary:The rolling contact between aluminium strips and rolls of different materials, in which the rolls were heated in situ with an auxiliary furnace to a temperature similar to that of the strips, was studied. Rolls of solid alumina failed during the rolling of the aluminium strip; all the other rolls, including plasma spray-coated rolls, remained undamaged. Examination of the structure and composition of the coatings which developed on the rolls showed that there was more transfer for all the different rolls but that the variations between the rolls were much less than they were when the rolls were at ambient temperatures. The thick coatings formed on the rolls were predominantly aluminium metal and the characteristic structure was independent of the original roll surface structures.
