Abstract
In this work, reliability and reproducibility of
cross-sectional scratch test has been studied for plasma
sprayed yttria-stabilized zirconia and TiO 2 coatings
with NiCr bondcoat. The scratch test was conducted on the
cross-section of the spray coatings. An image of the
scratched area was taken after testing using an optical
microscope in order to determine failure mode. With a
statistical evaluation, the adhesion and cohesion
strength were determined. The results show that the
scratch test on a cross-section can be used as an
effective and quantitative way for estimation of adhesion
or cohesion strength of plasma spray coating
