Purpose

This paper aims to analyze the corrosion behavior in Ringer solution of six commercially used Ni-based alloys that are present and commonly used as metallic biomaterials.

Design/methodology/approach

The specimens were received in the form of cylindrical ingots and were cut to get five samples of each brand with a cylindrical shape of 2 mm height to conduct the study. In this scientific research, the following techniques were used: open circuit potential, potentiodynamic polarization studies, and electrochemical impedance spectroscopy.

Findings

The study findings revealed the passivation tendency of the different specimens. Additionally, when the materials were compared, it was discovered that the decisive factor for high corrosion resistance was the chromium concentration. However, with similar chromium content, the stronger concentration in molybdenum increased the resistance. According to the results obtained in this investigation, the biological safety of the dental materials studied in Ringer solution was considered very high for specimens 1 and 2, and adequate for the other samples.

Originality/value

Metal alloys used as biomaterials in contact with the human body should be deeply investigated to make sure they are biocompatible and do not cause any harm. The corrosion resistance of an alloy is the most important characteristic for its biological safety, as all problems arise because of the corrosion process. There is scarce investigation in these Ni-based dental biomaterials, and none found in these commercially used dental materials in Ringer solution.

几种商用金属合金在林格溶液中的腐蚀行为

目的

本文旨在分析六种商业使用的镍基合金在林格溶液中的腐蚀行为，这些合金通常用作金属生物材料。

设计/方法/方法

样品以圆柱形锭的形式接收并切割以获得每个品牌的五个样品，具有 2 毫米高的圆柱形形状以进行研究。在这项科学研究中，使用了以下技术：开路电位、动电位极化研究和电化学阻抗谱。

发现

研究结果揭示了不同试样的钝化趋势。此外，当比较材料时，发现高耐腐蚀性的决定性因素是铬浓度。然而，在铬含量相似的情况下，钼的浓度越高，电阻越大。根据本次调查获得的结果，在林格溶液中研究的牙科材料的生物安全性对于样本 1 和 2 被认为非常高，对其他样本来说是足够的。

原创性/价值

应深入研究用作与人体接触的生物材料的金属合金，以确保它们具有生物相容性且不会造成任何伤害。合金的耐腐蚀性是其生物安全性的最重要特征，因为所有问题都是由腐蚀过程引起的。对这些镍基牙科生物材料的研究很少，在这些商业使用的牙科材料中没有发现林格溶液。
