Abstract:The measurements of the surface temperature fields of laser re-melting area in the Zn-Al based ceramic thin film, scanning heating by CO2 laser, were carried out with an HSC-31 fast-scanning infrared thermovision. The center and edge temperatures of melting pool, and the isotherms of different temperatures, and the shape of the melting pool were measured.
Key words: Zn-Al based alloys; metal matrix composites(M MC); laser re-melt; surface temperature fields
