Abstract

The bonding strength between titanium and ceramic were analyzed according to the bonding agent and the coating methods of Au and TiN respectively. The bonding strength was measured through the 3 point bending test. Consequently, the bonding strength of the special bonding agent after the TiN coated (SPTB) group was $72.20({\pm}5.25)MPa$ which was the strongest one among groups. The bonding strength of the special bonding agent treated only (SPB) group was $67.66({\pm}12.10)MPa$, the special bonding agent after the Au coating SPGB group was $46.95({\pm}12.48)MPa$ and the SP group was $43.80({\pm}5.12)MPa$. Taking these results into account, the bonding strength of the SPB group shows the same as it of the SPTB group, however, it is stronger than SP group. And the TiN coated SPTB group shows the stronger bonding strength than the Au coated SPGB group.

티타늄 표면처리방법 중 gold 코팅, TiN 코팅, 그리고 전용결합재를 복합적으로 사용하여 티타늄과 세라믹의 결합강도에 미치는 영향을 분석하고자 하였다. 티타늄과 세라믹의 3점 굽힘 결합강도를 측정한 결과, TiN 코팅과 전용결합재로 처리한 SPTB군이 $72.20({\pm}5.25)MPa$로 가장 높게 나타났으며, 전용결합재로 처리한 SPB군($67.66({\pm}12.10)MPa$), gold 코팅과 전용결합재로 처리한 SPGB군($46.95({\pm}12.48)MPa$), 코팅과 전용결합재로 처리하지 않은 SP군$(43.80({\pm}5.12)MPa)$ 순으로 나타났다. 시편들의 결합강도를 통계 분석한 결과, 전용 결합재로 처리한 SPB군과 TiN코팅과 전용결합재로 처리한 SPTB군이 결합력이 유사하게 나타났으며, 전용결합재로 처리한 군(SPB)이 처리하기 않은 군(SP)에 비하여 결합력이 높게 나타났으며, TiN 코팅한 군(SPTB)이 gold 코팅한 군(SPGB)에 비하여 결합력이 높게 나타난 것으로 관찰되었다.
