Abstract

The purpose of this study was to investigate the role of different welding techniques: laser and tungsten inert gas (TIG) on the corrosion behavior of commercially pure titanium (cp-Ti) frameworks in dentistry. Electrochemical tests were conducted in artificial saliva at pH 7.2, 37°C. The surfaces were examined using scanning electron microscopy. The received data were analyzed by one-way ANOVA followed by Tukey’s test for multiple comparisons (α = 0.05). Cp-Ti frameworks welded by TIG were found to be more susceptible to corrosion, where defects in the weld region appeared to be the most important factor for the corrosion behavior. These findings suggested a better corrosion behavior for the laser welding procedure.

钛框架在激光和钨极惰性气体保护焊下的腐蚀行为：在牙科中的应用

摘要

这项研究的目的是研究不同焊接技术的作用：激光和惰性气体钨（TIG）对商业纯钛（cp-Ti）骨架在牙科中的腐蚀行为的影响。在pH 7.2、37°C​​的人造唾液中进行电化学测试。使用扫描电子显微镜检查表面。接收的数据通过单向方差分析进行分析，然后进行Tukey检验进行多次比较（α= 0.05）。发现TIG焊接的Cp-Ti骨架更容易受到腐蚀，其中焊接区域的缺陷似乎是腐蚀行为的最重要因素。这些发现表明激光焊接过程具有更好的腐蚀性能。
