摘要:
选用适合制造活塞环的ZL110铝合金作为基体，将Al2O3和TiO2粉末按照不同质量比例混合，采用等离子喷涂技术在其表面制备出3种复合陶瓷涂层，分别为：97%Al2O3+3%TiO2涂层、80%Al2O3+20%TiO2涂层、40%Al2O3+60%TiO2涂层。通过观察形貌、计算孔隙率，分析复合陶瓷涂层的平整度和致密性。通过测定厚度、硬度并进行高温摩擦实验，分析复合陶瓷涂层的高温耐磨性能。结果表明：97%Al2O3+3%TiO2涂层、80%Al2O3+20%TiO2涂层和40%Al2O3+60%TiO2涂层均呈现片层堆叠结构，厚度基本一致，为(204±1) μm，且物相相同。与97%Al2O3+3%TiO2涂层和40%Al2O3+60%TiO2涂层相比，80%Al2O3+20%TiO2涂层表面相对平整且致密性较好，其硬质相α-Al2O3含量达到20.5%。80%Al2O3+20%TiO2涂层的硬度为856.4 HV，较基体ZL110铝合金提高约9倍，同时表现出良好的高温耐磨性能。
Abstract:
ZL110 aluminum alloy, which was selected as the substrate, was suitable for manufacturing piston ring. Al2O3 and TiO 2 powders were mixed in different mass ratios, and three composite ceramic coatings were prepared on its surface by plasma spraying, namely 97%Al2O3+3%TiO2 coating, 80%Al 2O3+20%TiO2 coating and 40%Al 2O3 + 60%TiO2 coating. The flatness and compactness of composite ceramic coating were analyzed by observing the morphology and calculating the porosity. The high-temperature wear resistance of composite ceramic coating was analyzed by measuring the thickness, hardness and conducting high-temperature friction test. The results show that 97%Al 2O3+3%TiO2 coating, 80%Al 2O3+20%TiO2 coating and 40%Al 2O3+60%TiO2 coating all present a layered stacking structure, with a consistent thickness of (204±1) μm and the same phase. Compared with 97%Al 2O3+ 3%TiO2 coating and 40%Al 2O3+60%TiO2 coating, 80%Al 2O3+20%TiO2 coating has a relatively flatter surface and better compactness, and the content of α-Al2O3 hard phase reaches 20.5%. The hardness of 80%Al 2O3+20%TiO2 coating is 856.4 HV, which is about 9 times higher than that of the ZL110 aluminum alloy substrate, and it also shows good high-temperature wear resistance.
