Characterization of a new polysiloxane-based titanium surface treatment for resin titanium bonding

摘要

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 state…
