摘要
采用多弧离子镀技术在0Cr15Ni5Cu2Ti钢表层制备TiAlSiN涂层;采用X射线衍射分析膜层的物相成分;利用显微硬度计检测涂层的硬度;利用扫描电镜观察TiAlSiN涂层的形貌;利用能谱仪对涂层表面的组成及含量采取分析;采用自动划痕仪测定涂层结合力;用高温热处理炉对涂层进行高温抗氧化实验。结果表明:基材经多弧离子镀膜,其表面均匀平整、致密度高,但有一定量的微孔洞和大颗粒。镀有TiAlSiN涂层的试样平均硬度达到1971.4HV0.2。镀有TiAlSiN涂层的试样与原始0Cr15Ni5Cu2Ti钢的相比,其氧化速率远低于原始0Cr15Ni5Cu2Ti钢的,而高温抗氧化性优于原始0Cr15Ni5Cu2Ti钢。划痕实验结果表明:膜基结合力约10N,此次实验涂层与基材的结合力较低。
The surfaces of 0 Cr15 Ni5 Cu2 Ti steel were modified with TiAlSiN coating deposited by TiAlSiN coatings.The influence of the microstructures and phase structures of the TiAlSiN coating on the high temperature oxidation resistance and interfacial adhesion was investigated with X-ray diffraction,scanning electron microscope,energy dispersive spectroscope and micro-hardness tester.The preliminary results show that when it comes to property modification,the TiAlSiN coating makes the difference.To be specific,the fairly uniform,compact TiAlSiN coating,with randomly distributed micro-pores and large "droplets",increased the average micro-hardness to 1971.4 HV0.2,significantly decreased the oxidation rate,and considerably enhanced the high-temperature oxidation-resistance.Much research remains to be done to increase the rather low interfacial adhesion(with a binding force of ~10 N).
