AB - Al-Si alloys are characterized with 3.3.- miniSIMS DEPTH PROFILES
a range of properties which make
them potential materials to
substitute cast iron in automotive
engines. The formation of
polyphosphate films on Al-Si
alloys would indicate the potential
use of ZDDP in lubrication of
these alloys and hence facilitate
their use as replacement materials
for cast iron. It has been shown
that the addition of MoDTC assists
ZDDP to reduce friction and wear
of hypereutectic Al-Si alloys. The
aim of the current work is to fully
characterize these two different
kinds of tribofilms formed on the
Al-Si alloy, showing the different
surface interactions as a function
of the presence of MoDTC in the
tribofilm formation, as well as the
different distribution and
mechanical properties of the
tribofilm.
