The use of dental implants is growing rapidly for the last few decades and Ti-based dental implants are a commonly used prosthetic structure in dentistry. Recently, the combined effect of corrosion and wear, called tribocorrosion, is considered as a major driving process in the early failure of dental implants. However, no previous study has reported the prediction of tribocorrosion processes in advance. Therefore, this study is a novel investigation on how the acoustic emission (AE) technique can predict tribocorrosion processes in commercially-pure titanium (cpTi) and titanium-zirconium (TiZr) alloys. In this study, tribocorrosion tests were performed under potentiostatic conditions and AE detection system associated with it captures AE data. Current evolution and friction coefficient data obtained from the potentiostatic evaluations were compared with AE absolute energy showcased the same data interpretation of tribocorrosion characteristics. Other AE data such as duration, count, and amplitude, matched more closely with other potentiostatic corrosion evaluations and delivered more promising results in the detection of tribocorrosion. Hence, AE can be consider as a tool for predicting tribocorrosion in dental implants. Experimental results also reveal Ti5Zr as one of the most appropriate dental implant materials while exposing Ti10Zr's lower effectiveness to withstand in the simulated oral environment.

在过去的几十年中，牙科植入物的使用正在迅速增长，并且钛基牙科植入物是牙科中常用的修复结构。近来，腐蚀和磨损的综合效应被称为摩擦腐蚀，被认为是牙科植入物早期失效的主要驱动过程。但是，以前没有研究报道过对摩擦腐蚀过程的预测。因此，这项研究是关于声发射（AE）技术如何预测商业纯钛（cpTi）和钛锆（TiZr）合金中摩擦腐蚀过程的新颖研究。在这项研究中，在恒电位条件下进行了摩擦腐蚀试验，并且与之相关的AE检测系统捕获了AE数据。从恒电势评估获得的当前演变和摩擦系数数据与AE绝对能量进行了比较，显示了摩擦腐蚀特性的相同数据解释。其他AE数据（例如持续时间，计数和幅度）与其他恒电位腐蚀评估更紧密地匹配，并且在摩擦腐蚀的检测中提供了更有希望的结果。因此，AE可以被认为是预测牙科植入物中摩擦腐蚀的工具。实验结果还表明，Ti5Zr是最合适的牙科植入物材料之一，同时暴露了Ti10Zr在模拟口腔环境中承受的较低功效。与其他恒电位腐蚀评估更紧密地匹配，并在摩擦腐蚀的检测中提供了更可喜的结果。因此，AE可以被认为是预测牙科植入物中摩擦腐蚀的工具。实验结果还表明，Ti5Zr是最合适的牙科植入物材料之一，同时暴露了Ti10Zr在模拟口腔环境中承受的较低功效。与其他恒电位腐蚀评估更紧密地匹配，并在摩擦腐蚀的检测中提供了更可喜的结果。因此，AE可以被认为是预测牙科植入物中摩擦腐蚀的工具。实验结果还表明，Ti5Zr是最合适的牙科植入物材料之一，同时暴露了Ti10Zr在模拟口腔环境中承受的较低功效。
