Abstract
The invention relates to a strip composite material with a base material of a metal or a metal alloy and a tin coating on the surface, whereby an intermetallic phase (IMP) is formed between the base material and the coating. In particular for achieving good wear and corrosion resistance of the composite material with a simultaneously oxide-free surface, 1 to 50 At.-%, preferably 6 to 30 At.-%, carbon (C) are embedded in an outer surface region of the tin coating up to a thickness D of approximately 2 .mu.m. A method (oil treatment) and apparatus for the manufacture of the composite material of the invention are also disclosed.
