Abstract The fretting capabilities of 690 alloy against 405 stainless steel were evaluated through a series of tube-plate tests in different experimental conditions. The results indicated that as the temperature increased in air, the wear volume and wear depth increased first until reaching a maximum value at 90 °C and then decreased. This was attributed to spinel oxides formed above 200 °C in combination with adhesive wear, which contributed to oxidation resistance and a reduction of interfacial wear, resulting in the decrease of wear volume and wear depth. Metallic nickel, iron and chromium were observed in water, which indicated low oxidation, associated with lower wear damage.

环境条件对690合金微动磨损化学行为的影响

摘要 通过一系列不同实验条件下的管板试验，评估了690合金对405不锈钢的微动磨损能力。结果表明，随着空气中温度的升高，磨损量和磨损深度先增加，直到在 90°C 时达到最大值，然后才减小。这归因于在 200°C 以上形成的尖晶石氧化物与粘附磨损相结合，这有助于抗氧化和减少界面磨损，导致磨损量和磨损深度减少。在水中观察到金属镍、铁和铬，这表明低氧化，与较低的磨损损坏相关。
