Several discharge areas by laser-guided discharge
(LGD) were compared with those by common arc discharge. The
randomicity of discharge areas by common arc discharge was
controlled by laser guiding on two scales: large scale (the spacing
of the discharge areas) and small scale (the inside of the discharge
area). The position of the discharge area overlapped completely
with a laser focus; therefore, the distribution and surface shape of
the discharge areas were controlled. The stochastic movement of
anode spot in the discharge area was controlled by laser guiding.
As such, the repetitive melting and solidifying of microstructures
in the discharge area was constrained. The tempered microstruc-
tures in the discharge area were voided, the utilization efficiency
of input energy was improved, and the strengthened depth of the
discharge areas was increased. The regularity of cross-sectional
shape of the discharge area was also improved. The hardness of
microstructures in both discharge areas is greater than that of the
base material. The highest level of hardness of microstructures in
both discharge areas measures above 1000 HV. In summary, the
hardness ofmicrostructures in the discharge area by LGD is larger
and more discrete than that by common arc discharge.
