We study the influence of temperature of a working medium and loading frequency on the contact fatigue of 20KhN3A and ShKh15 steels in oil and in a 3% NaCl aqueous solution. It is shown that, as the loading frequency increases, the contact fatigue of steels increases in a 3% NaCl aqueous solution but does not change in oil. At the same time, as temperature increases, the contact fatigue decreases in a 3% NaCl aqueous solution but remains almost constant in oil. It is shown that the outlined behaviors of the analyzed steels is explained by the action of the components of working media and their concentrations in the surface layers in the course of the tests.

温度和加载频率对20KhN3A和ShKh15钢在腐蚀性介质作用下接触疲劳的影响

我们研究了工作介质温度和加载频率对 20KhN3A 和 ShKh15 钢在油中和 3% NaCl 水溶液中的接触疲劳的影响。结果表明，随着加载频率的增加，钢在 3% NaCl 水溶液中的接触疲劳增加，但在油中没有变化。同时，随着温度升高，接触疲劳在 3% NaCl 水溶液中降低，但在油中几乎保持不变。结果表明，在试验过程中，工作介质成分的作用及其在表层中的浓度可以解释所分析钢的轮廓行为。
