Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The aim of the study was to improve the
lamellar structure and wear resistance of
arc-sprayed coatings. FeNiCrAl arc-sprayed
coatings were remelted by the tungsten inert gas
welding method. The as-sprayed and remelted
specimens were subjected to comparative structural
phase composition examination using optical
microscopy, scanning electron microscopy
and X-ray diffraction. Additionally, the effect
of the remelting treatment on the wear mechanism
of the arc sprayed coatings was also studied.
It was found from the experiments that the
tungsten inert gas surface process has the potential
to form pore- and crack-free coatings. Further
investigations showed that the dominant
mechanism of wear for the as-sprayed coatings
was oxide delamination and for the tungsten
inert gas remelted coatings was cutting and
ploughing |
