Nikasil®
coating
Nikasil®
is
a
surface
protection layer
for
a
coating procedure
devel-
oped
by
Mahle. The
name
is derived from the
two
materials used
in this
procedure
-
a
layer
of nickel into which is embedded the
particularly
hard
silicone carbide.
The
most
important advantages
of the
Nikasil®
coating
are
very
good
heat
conductivity,
resulting
in
much
improved performance,
low
wear,
and
a
lightweight cylinder.
