Abstract Different coating technologies imply a large variation in the properties of the deposited material. This work compares, for the first time, the wear and corrosion performance of Stellite 6® coatings applied onto substrates of low carbon steel by the Gas Tungsten Arc Welding hot-wire cladding and by High Velocity Oxygen Fuel spraying technologies. The impact of the microstructure and mechanical properties in the wear and corrosion results are also discussed. Slurry erosion tests are performed at two solid particles impact angles, 30° and 90°, and impact velocities of 3.61 and 9.33 m/s. Abrasive wear performance of the coatings was determined following the ASTM G-65-04 standard. Electrochemical impedance spectroscopy is applied for corrosion evaluation. HVOF sprayed coatings have performed better in abrasive wear while GTAW hotwire cladding coatings have shown higher resistance to erosive wear and better performance in corrosion tests.

通过 HVOF 喷涂和 GTAW 热线包覆施加的 Stellite 6® 涂层的磨损和腐蚀性能

摘要 不同的涂层技术意味着沉积材料的性能有很大差异。这项工作首次比较了通过气体钨极电弧焊热丝包覆和高速氧燃料喷涂技术涂覆在低碳钢基材上的司太立 6® 涂层的磨损和腐蚀性能。还讨论了微观结构和机械性能对磨损和腐蚀结果的影响。泥浆侵蚀测试在两个固体颗粒冲击角 30° 和 90° 以及 3.61 和 9.33 m/s 的冲击速度下进行。涂层的磨料磨损性能根据 ASTM G-65-04 标准确定。电化学阻抗谱用于腐蚀评估。
