Abstract

Results are reported of the effects of surface melting (sealing) produced by a 1 kW laser in pulsed mode on the structure of plasma-sprayed 8wt% yttria partially stabilized zirconia (YPSZ); pulse lengths in the range of 1 to 90msec were used. Smooth surfaces were produced with shallow cracks at values of laser energy 5 to 40 J. Comparison of the data is made with results obtained by sealing using continuous wave CO2 laser processing.
