- 摘要:
- 为提高钢材表面等离子喷涂涂层的性能，利用真空热压工艺对原始涂层进行处理，通过对比涂层内部结构、结合强度、显微硬度、摩擦性能,分析真空热压工艺对等离子喷涂涂层性能的影响。结果表明，经过热压处理后，离子喷涂涂层内部组织致密均匀，摩擦损失量变小，基体与涂层结合强度与平均显微硬度均增大，摩擦性能得到提升，改善了离子喷涂涂层的整体性能。
- Abstract:
- In order to improve the performance of plasma spraying coating on steel surface, the original coating was treated by vacuum hot pressing process. The effect of vacuum hot pressing technology on the performance of plasma spraying coating was analyzed by comparing the internal structure, bonding strength, microhardness and friction properties of the coatings. The results showed that after hot pressing treatment, the internal structure of the coating was compact and uniform, the friction loss was small, the bonding strength of the substrate and the average microhardness of the coating increased, the friction property was better, and the overall performance of the plasma spraying coating was improved.
