Abstract | Purpose: To characterize the polysiloxane-coated titanium
surface with thermal treatment by XPS and AFM. Such a novel
coating might significantly enhance resin bonding.
Methods and materials: A layer (∼2mm) of silicone grease
(Dow Corning Co., Michigan, USA) was applied on two titanium plates (Permascand, Ljungaverk, Sweden) followed by
a thermal treatment at two temperatures, 800 and 1100 ◦C,
respectively. Another titanium plate was surface treated by
sandblasting. The atomic composition of titanium surfaces
and change of chemical states of Ti2p, Si2p and O1s were
examined by X-ray photoelectron spectroscopy (XPS). The surface morphology and surface roughness were examined by
atomic force spectroscopy (AFM).
Results: Change in binding energies for Si2p and O1s
peaks were observed after surface treatment by sandblasting
and a polysiloxane coating with thermal treatment (Table 1).
No observable changes in binding energies for Ti2p was
obtained. There was a change in atomic composition of
titanium surfaces after different surface treatments. There
were changes in surface morphology of titanium after surface treatments. The average surface roughness, Ra (m),
of titanium was increased after sandblasting and thermal
treated of polysiloxane-coating: polished (0.179 ± 0.027), sandblasted (0.642 ± 0.033), polysiloxane-coated at 800 and 1100 ◦C
(0.316 ± 0.056 and 0.898 ± 0.064).
Conclusion: Both the physical and chemical characteristics
of the titanium surfaces were changed by the surface modification using a polysiloxane coating with thermal treatment.
These changes on the titanium surface might affect the resin
titanium bonding. |
