本研究的目的是用氟和银对牙科器械表面进行改性，并检验这种新的表面改性方法的有效性。采用等离子体基氟离子和银离子注入沉积的方法对不锈钢板材进行改性。通过XPS、接触角和刷磨试验对涂层的表面特性和耐刷磨性进行了评价。改性样品的XPS谱显示有氟和银的峰。即使在刷磨试验后也能检测到这些峰。由于氟离子和银离子的注入-沉积，水的接触角显著增加。此外，在相同的刷牙次数下，改性试件的接触角明显高于纯氟沉积试件。研究表明，这种新型的氟离子和银离子注入沉积表面改性方法提高了涂层的耐刷性、耐磨性和疏水性，是一种潜在的抗菌器件。
The aims of this study were to modify dental device surface with fluorine and silver and to examine the effectiveness of this new surface modification method. Stainless steel plates were modified by plasma-based fluorine and silver ion implantation-deposition method. The surface characteristics and brushing abrasion resistance were evaluated by XPS, contact angle and brushing abrasion test. XPS spectra of modified specimens showed the peaks of fluoride and silver. These peaks were detected even after brushing abrasion test. Water contact angle significantly increased due to implantation-deposition of both fluorine and silver ions. Moreover, the contact angle of the modified specimen was significantly higher than that of fluorine only deposited specimen with the same number of brushing strokes. This study indicates that this new surface modification method of fluorine and silver ion implantation-deposition improved the brushing abrasion resistance and hydrophobic property making it a potential antimicrobial device.
