Abstract The present study deals with the analysis of erosion tribo-performance of Stellite-6 and Colmonoy-88 micron layers deposited on stainless steel 316 L by using high-velocity oxygen–fuel (HVOF) process. The average roughness of Stellite-6 and Colmonoy-88 deposited SS-316 L was measured as 5.69 and 6.67 μm respectively. The crack toughness of Stellite-6 and Colmonoy-88 deposited surface was evaluated as 19.8 ± 0.56 and 30.1 ± 0.29 MPa m1/2 respectively. Erosion wear experiments were performed by using a Ducom slurry pot tester at different process parameters. Results show that the relative erosion wear of SS-316 L and Stellite-6 was observed maximum at 30° impact angle whereas relative erosion of Colmonoy-88 was found maximum at 60°. Microhardness of SS-316 L was improved about 2.5–3.2 times with deposition of Stellite-6 and Colmonoy-88.

SS-316L 上 HVOF 沉积的 Stellite-6 和 Colmonoy-88 微米层的侵蚀摩擦性能

摘要 本研究涉及使用高速氧燃料 (HVOF) 工艺沉积在不锈钢 316 L 上的 Stellite-6 和 Colmonoy-88 微米层的侵蚀摩擦性能分析。Stellite-6 和 Colmonoy-88 沉积的 SS-316 L 的平均粗糙度分别测量为 5.69 和 6.67 μm。Stellite-6 和 Colmonoy-88 沉积表面的裂纹韧性分别评估为 19.8 ± 0.56 和 30.1 ± 0.29 MPa m1/2。通过使用 Ducom 浆料罐测试仪在不同的工艺参数下进行侵蚀磨损实验。结果表明，SS-316 L 和 Stellite-6 的相对侵蚀磨损在 30° 冲击角处观察到最大，而 Colmonoy-88 的相对侵蚀在 60° 处观察到最大。随着Stellite-6 和Colmonoy-88 的沉积，SS-316 L 的显微硬度提高了约2.5-3.2 倍。
