Pulse laser surface modification of poly-ether-ether-ketone for surface metallization

In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys electroless plating. The properties of metal layers on were characterized SEM, resistance tester and metallographic microscope, respectively. When laser energy density is relatively low (Q<60J·cm -2 ), there mainly photothermal effect surface substrate presents periodic undulating groove structure a small number holes. rather higher (Q≥60J·cm are simultaneously enhanced partial photochemical effect. As result, uniformly covered melted layer or re-solidified product after melting. Besides, nickel coatings have dense, uniform in good adhesion for sample treatments (Q>10J·cm which coating less than 20 mΩ. this paper, interaction mechanism studied metals prepared under laser-induced effect, provides technical support future aviation aerospace fields, such as, radar antenna.
