中文摘要:使用激光熔覆技术制备CeO_(2)含量不同的Ni/WC基熔覆层,以此提高45钢表面耐磨性能与耐腐蚀性能的同时,探究CeO_(2)添加量对熔覆层性能的影响。利用X射线衍射仪、能谱仪、扫描电镜、显微硬度计、摩擦磨损试验机、电化学工作站对熔覆层进行表征和测试。结果表明,适量的CeO_(2)能够提高熔覆层的成形质量,减少孔隙缺陷,增强其耐磨耐蚀性能。当CeO_(2)的质量分数为2%时,熔覆层中的孔隙缺陷几乎消失,并且具有最高的硬度以及最好的耐磨耐腐蚀性能。加入过量的CeO_(2)则会使熔覆层的成形质量变差,无法获得良好的熔覆层性能。
外文摘要:Laser cladding technology was used to prepare Ni/WC-based cladding layers with varying CeO_(2)contents to improve the wear and corrosion resistance of 45 steel surfaces.The effect of CeO_(2)addition on the properties of the cladding layer was also explored.The cladding layer was characterized using X-ray diffraction,energy-dispersive spectroscopy,scanning electron microscopy,microhardness testing,friction and wear testing,and electrochemical analysis.The results indicate that an appropriate amount of CeO_(2)improves the forming quality of the cladding layer,reduces the pore defects,and enhances its wear and corrosion resistance.When the mass fraction of CeO_(2)is 2%,pore defects nearly disappear,and the cladding exhibits the highest hardness,along with the best wear and corrosion resistance.However,an excessive CeO_(2)content negatively influences the cladding layer’s formation and performance.
