Abstract

Titanium bonding porcelain was synthesized by sol–gel process and Ti-bonding porcelain hybrid coatings were fused on Ti surface by using a 400 W pulse CO2 laser. The specimens were studied by field-emission scanning electron microscopy, X-ray diffraction and bonding tests. Titanium oxide layer with hierarchical structures consisting of submicron rows of leaf-like embossments and nano-pores was obtained by combining acid etching and anodization processes, which increased the surface roughness of Ti. Pure porcelain coatings with similar hierarchical structure containing submillimeter bioglass BEADs and micropores were synthesized on Ti surface by laser fusion. When the titanium content was 80 wt%, Ti-porcelain hybrid coating with hierarchical structure composed of porcelain islands, microparticles of titanium and micropores were obtained. With the titanium content increased, wettability between Ti-coating was improved and the bond strength increased accordingly, from 28.52 ± 3.63 to 39.14 ± 4.35 MPa.
