中文摘要：为了探究TiC含量对铁基涂层熔覆形貌与成形质量的影响,提升65Mn钢表面力学性能。采用激光熔覆技术在65Mn钢表面制备铁基TiC复合涂层,对比分析了不同TiC添加量对铁基熔覆层的成形质量(气孔率)、宽高比、显微硬度的影响。结果表明,随着TiC添加量的增高,宽高比呈现先增大后减小的趋势,当TiC的质量分数为30%时,宽高比达到最高5.31,此时的气孔率有所下降。适量地添加TiC能够有效提升复合涂层的硬度,但过高的TiC含量会造成熔池中气体过多,气孔率增大,无法获得良好的涂层性能。该研究结果对农机刀具领域具有一定的指导作用。

外文摘要：TiC-reinforced Fe-based composites are prepared to improve the surface mechanical properties of 65Mn steel and explore the effect of TiC content on the cladding morphology and forming quality of Fe-based coatings.The TiC/Febased ceramic composite coating was fabricated on the surface of 65Mn steel by laser cladding technology.The effects of different TiC contents on the quality(porosity),aspect ratio,and microhardness of the cladding layer are compared.The results show that with increasing TiC content,the aspect ratio first increases and then decreases.When the mass fraction of TiC is 30%,the aspect ratio reaches a maximum of 5.31,and the porosity decreases.The addition of an appropriate amount of TiC can effectively improve the hardness of the composite coatings,but very high TiC content results in excessive gas in the molten pool.Thus,the porosity increases and good coating performance cannot be obtained.The results of this study are expected to play a guiding role in the field of agricultural machinery tools.
