abstract = "Temperature distribution induced by laser radiation is a very important
parameter for an efficient and safe application of lasers in different ceramic
processing techniques. This paper presents the results of an infrared
thermography (IRT) application for monitoring temperature distribution on
a ceramic surface during Nd: YAG laser irradiation with different fluences
and 8ns pulse duration. FLIR, E40 and SC7200 IR cameras were used with
the aim of recording the maximum temperature in the irradiated zones. It
was expected that IRT could give some information related to the heat
affected zone and possible damage to the base material; however, the results
have shown that IR cameras, even those with high performance such as
SC7200, cannot record the maximum temperature value at the moment of
laser operation, but only the average temperature of the bulk sample
material after laser pulses. The results of the numerical simulation have
confirmed the value of the thermographic measurements. The microstructure
and micromorphology of the ceramic surface before and after the laser
treatment were analysed by optical and scanning electron microscopy as
well as by examining the roughness of the irradiated and non- irradiated
surfaces, while the micromechanical changes were analysed by comparing
the micro-hardness of the irradiated and non-exposed surfaces.",
