Abstract.
Identification of engineering surfaces damage modes requires
the selections of appropriate analytical techniques for
characterisation of morphology, rheology as well as of physical &
chemical properties. Different techniques of visual observations,
based on optical and electronic microscopy, coupled with specific
image analysis software are presented and discussed. The authors
shear their experience in specific case studies.
Different strategies are discussed and numerous examples commented
and illustrated for solving, choosing, and diagnosing various
tribology problems by using contact mechanics, solid mechanics,
system dynamics, physical chemistry, engineering materials science,
lubricant chemistry, and metallurgy knowledge.
Below, a functional simplified diagram is presented, based on 30
years of experience and 1000 expertises. Some case studies are
analysed in-depth.
