Abstract
Nano-structured TiAlCrYN coatings, grown by
unbalanced magnetron sputtering on various steel substrates,
exhibited friction coefficients 0.6–0.8 and wear coefficients 10-16–10-15 m3 N-1 m-1 in dry sliding wear tests. This article reports comprehensive worn surface analyses using SEM, TEM , EDX, EELS and Raman spectroscopy.
A *80 nm thick tribofilm formed on the TiAlCrYN worn
surface was found to have dense amorphous structure and
homogeneous oxide composition of Cr0.39Al0.19Ti0.20Y0.01
O0.21. Viscous flow of the amorphous tribofilmwas dominant
in causing the high friction coefficient observed. The coatings showed combined wear mechanisms of tribo-oxidation
and nano-scale delamination.
