This research employs Kelvin probes to study the corrosion behavior of metallic surfaces. The investigators are constructing a potentiostat/galvanostat system using the Kelvin vibrator as a contactless reference electrode. The Kelvin probe is a sensor for determining the corrosion potential of materials exposed to thin film electrolytes. This system is used for the measurement of the corrosion potential and corrosion current versus time of homogeneous and of galvanically coupled metals under very thin electrolyte layers and humidity films. The devise is also used to determine effects of substrate-induced heterogeneities and defects on the semiconducting properties of anodically grown titanium dioxide. %%% This research is making significant strides in new understanding of atmospheric corrosion. The Kelvin probe permits electrochemical measurements through precisely controlled electrolyte films within specific pollutant atmospheres.

这项研究采用开尔文探针来研究金属表面的腐蚀行为。 研究人员正在构建一个使用开尔文振动器作为非接触式参比电极的恒电位仪/恒电流仪系统。 开尔文探针是一种用于确定暴露于薄膜电解质的材料的腐蚀电位的传感器。 该系统用于测量非常薄的电解质层和湿膜下均质金属和电耦合金属的腐蚀电位和腐蚀电流随时间的变化。 该装置还用于确定基底引起的异质性和缺陷对阳极生长二氧化钛的半导体特性的影响。 %%% 这项研究在对大气腐蚀的新认识方面取得了重大进展。 开尔文探针允许通过特定污染物气氛中精确控制的电解质膜进行电化学测量。
