Abstract
The systematic design and optimization of performance of
coated surfaces suffers from lack of suitable procedures
to carry out such an analysis. A tribological contact
with two loaded surfaces in relative motion is a complex
system requiring a general three-dimensional finite
deformation and finite sliding contact analysis in order
to succeed. Such analyses were carried out for a 2 m TiN
coating on a tool steel substrate. The analyses were
performed to simulate the whole scratch test and the
results subjected to a fracture mechanical analysis. A
methodology and a model for attaining fracture toughness
directly using the cracking patterns of a scratch test
and finite element analysis results is presented. The
fracture mechanical model is verified by comparing the
attained fracture toughness values to literature values.
