Abstract
A process for marking a surface of a refractory ceramic part, known as the 'surface to be marked.' The part has a microstructure of grains including more than 50% by mass of ZrO, bound by a silicate binder phase, and a total porosity of less than 5% by volume. The process involves irradiation of the surface with a laser beam. The beam is emitted by a laser device set to comply with relationship: a.V+b.F+c.VF+d.V+e. F+f<0, in which: a=10. D+2×10, b=0.5×10. D−150×10, c=0.5×10. D−300×10, d=5×10. D−2.5×10, e=−5×10. D+2.0×10, and f=−5×10. D+1.8×10. V is expressed in mm/second, D is expressed in mm and F is expressed in kHz.
