The present study investigated the effectiveness of several surface pretreatment
methods on the bonding of Ti to adhesive resin. Commercially pure Ti and Ti-6Al-4V
alloy were bonded by 4-META/MMA-TBB resin to stainless steel rods. Each specimen
was polished with No.1.000 sandpaper and then treated with various surface treatment
methods, such as 50 §­ size of Al2O3 particles sandblasting,
tinplating, silicoating, combination of sandblasting and tinplating and combination of
sandblasting and silicoating.
The surface of pure Ti treated with sandblasting was roughened to irregular and
retentive pattern and aluminum content on the treated surface was increased. The
surface morphology treated with tinplating was similar to nontreated one and the surface
composition showed almost no change. The surface morphology of silicoating groups
was similar to the one of silicoated after sandblasting condition and in both group,
carbon content was significantly increased. The surfaces morphology of tinplating after
sandblasting groups were similar to those of sandblasting groups and surface
composition after tinplating was not changed at all. The surface observation results of
commercially pure Ti and Ti-6Al-4V alloy specimens were similar, but Ti-6Al-4V alloy
showed more amount of tin precipitations at tinplating groups.
Average tensile bond strength of each group was ranged from 21.20 to 31.64 MPa.
The tensile bond strength of each group did not show a difference at the 0.05
significance in one-way ANOVA test.
Fracture mode of each specimen was almost resin cohesive fracture, and some
adhesive fracture-like area was proved to be cohesive fracture in higher magnification.
Thus, bonding strength of resin-Ti interface was stronger than that of
4-META/MMA-TBB resin itself.
