Tartalmi leírás:
The aim of this paper is to
investigate the
possible application of
the
cavitation phenomenon as efficient method to
modify
the
surface properties
(e.g.
the surface roughness
)
in
the
nano and
micro
levels. A
luminum alloy (AlSiMg)
specimens were
subjected to high
speed
submerged cavitating jets under
various
working conditions, for short time
periods between 15 and 30 seconds. The force generated by
the
cavitating jet
is employed to modify the surface
roughness
of the specimen
. The
target surface was analyzed with
o
ptical microscopy, white light interferometry,
a
tomic
f
orce
m
icroscopy (AFM) and also with
e
lectrostatic
f
orce
m
icroscopy (EFM). The result
s show
the possibility to use
the
cavitation bubbles
as a nanofabrication method
e.
g. for
shotless surface peening.
With
AFM
, the deformation
mechanism and the formation of planar or wavy slip were also
investigated
.
EFM shows that the
changes in the surface
roughness also have
a strong
influence
on
the electrostatic field above a biased
sample.
