研究了一种新型的碳化硅（SiC）涂层对氟磷灰石玻璃陶瓷贴面化学耐久性的影响，通过检查重量损失和离子释放水平。测试了这种新型涂层将表现出显着的耐腐蚀性的假设。电感耦合等离子体原子发射光谱仪（ICP）用于离子浓度测定和扫描电子显微镜（SEM）用于表面形貌分析。将样品浸入pH 10和pH 2缓冲溶液中，以代表口腔中的极端条件。在第15天和第30天进行分析。SiC涂覆组在所有溶液和时间点上显示出重量损失的显著减少（p < 0.0001）。离子释放分析表明，对于SiC涂覆的盘，离子的释放略微降低或显著降低。SEM分析揭示了SiC涂覆组的表面平坦化。涂覆的样品的表面不像未涂覆的样品那样被腐蚀，这表明这些涂层的保护性质。总之，SiC是一种新型涂层，有望改善牙科应用陶瓷材料的性能。
The effect of a novel silicon carbide (SiC) coating on the chemical durability of a fluorapatite glass-ceramic veneer was investigated by examining weight loss and ion release levels. The hypothesis that this novel coating will exhibit significant corrosion resistance was tested. Inductively coupled plasma atomic emission spectrometer (ICP) was used for ion concentration determination and scanning electron microscopy (SEM) for surface morphology analyses. Samples were immersed in pH 10 and pH 2 buffer solutions to represent extreme conditions in the oral cavity. Analyses were done at 15 and 30 days. The SiC coated group demonstrated significant reduction in weight loss across all solutions and time points (p < 0.0001). Ion release analyses demonstrated either a marginally lower or a significantly lower release of ions for the SiC-coated disks. SEM analysis reveals planarization of surfaces by the SiC-coated group. The surfaces of coated samples were not as corroded as the non-coated samples, which is indicative of the protective nature of these coatings. In conclusion, SiC is a novel coating that holds promise for improving the performance of ceramic materials used for dental applications.
