中文摘要:
      目的 通过对滚轮表面制备超硬纳微米TiAlSiN涂层,提高滚轮的综合工作性能。方法 采用阴极电弧离子镀膜技术在滚轮工作面及高速钢试样表面制备超硬纳微米TiAlSiN涂层。通过X射线荧光测量系统测量涂层厚度,采用扫描电子显微镜(SEM)观察涂层表面特征和形貌,采用能谱仪(EDS)对涂层元素的成分进行分析,通过纳米压痕仪及洛氏硬度计对涂层的硬度及膜基结合力进行测定和分析。结果 滚轮表面1.97 μm厚的TiAlSiN涂层的Si原子数分数为4.21%,其显微硬度为37.69 GPa,涂层与基体的膜基结合力符合VDI-3198工业等级的HF3,呈现出较强的膜基结合力。经生产线上滚压机实际成形加工验证,涂层后滚轮的工作寿命是未涂层滚轮的5倍,滚轮具有强度高、耐磨损、抗氧化、耐腐蚀、粘附性降低等特性,显著改善了磨损、剥落、疲劳裂纹、缠辊、粘滚等现象。结论 在滚轮表面制备超硬纳微米TiAlSiN涂层,能显著提高滚轮的综合工作性能。
英文摘要:
      The work aims to improve comprehensive working performance of roller by preparing superhard nano TiAlSiN coating on roller surface. Superhard nano micron TiAlSiN coating was deposited on the surface of roller working surface and high-speed steel sample by applying cathodic arc ion-plating technique. Coating thickness was measured with X-ray fluorescence measurement system, surface characteristics and coating morphology were observed with scanning electron microscopy (SEM), coating elements composition were analyzed with energy dispersive spectrometer (EDS), and coating hardness and coating-substrate adhesion strength were measured and analyzed with nanoindentation and Rockwell hardness tester. Si content of 1.97 μm thick TiAlSiN coating on the roller surface was 4.21at.%, the microhardness was 37.69 GPa, and coating-substrate adhesion strength was HF3 in accordance with VDI-3198 industrial grade, and the adhesion strength was fairly strong. Verified by actual forming by roller press on production line, working life of coated roller was 5 times that of the uncoated one, roller featured in high strength, wear resistance, oxidation resistance, corrosion resistance, reduced adhesion strength, etc. Abrasion, spalling, fatigue crack, roll winding up, adhesive rolling, etc. were significantly improved. Superhard nano TiAlSiN coating prepared on roller surface can significantly improve comprehensive working performance of the roller.
