The purpose of the present study was to examine the effectiveness of a DLC-coating for preventing corrosion of an oral implant abutment made of Ti in an acidic fluoride solution. The amount of Ti ions released from the DLC-coated Ti was 0.20±0.07 ng/cm^2, which was significantly smaller than the amount released from the as-polished Ti (235.8±38.7 ng/cm^2, p<0.01). After the immersion test, Ra value for the as-polished Ti was increased to 48.3±7.3 nm due to corrosion, while that for the DLC-coated Ti was 5.8±1.8 nm. The results suggest that a DLC film is effective for increasing the corrosion resistance of pure titanium.
