Inconel 718 alloy is often used for the oil and gas industry, which usually failed due to the erosion-corrosion of multi-phase flow. In this study, we expect to enhance the wear and erosion-corrosion resistance of Inconel 718 alloy by liquid nitriding and a high-hardness nitrided layer with the thickness of about 9.5 μ m on the surface of Inconel 718 alloy was formed by liquid nitriding. Wear and erosion-corrosion tests were performed on untreated and nitrided Inconel 718 alloys. Results show that abrasive wear and adhesive wear occurred in both nitrided and untreated samples at different temperatures (25 °C, 100 °C and 200 °C). The width and depth of the wear track and the wear rate of the nitrided samples are all smaller than that of the untreated samples. Liquid nitriding significantly improves the wear resistance of Inconel 718 alloy because of the high-hardness nitrided layer. The nitrided Inconel 718 alloy exhibited an improvement of almost 80.3% in the erosion-corro...

通过液氮化提高Inconel 718合金的耐磨耗性

Inconel 718合金通常用于石油和天然气行业，通常由于多相流的腐蚀腐蚀而失败。在这项研究中，我们期望通过液体氮化来增强Inconel 718合金的耐磨性和耐腐蚀腐蚀性能，并且通过液体氮化在Inconel 718合金表面形成厚度约为9.5μm的高硬度氮化层。在未经处理和氮化的Inconel 718合金上进行了磨损和腐蚀腐蚀测试。结果表明，在不同温度（25°C，100°C和200°C）下，氮化和未处理的样品均发生磨料磨损和粘着磨损。磨损痕迹的宽度和深度以及渗氮样品的磨损率均小于未处理样品的磨损宽度和深度。液态氮化由于具有高硬度的氮化层，因此可以显着提高Inconel 718合金的耐磨性。氮化的Inconel 718合金的腐蚀腐蚀性能提高了近80.3％。
