摘要

采用激光熔覆法制备原位合成的xNbC，增强了AISI1045钢表面ni - 20w - C涂层。研究了NbC合成对金属基复合材料（MMC）涂层显微组织、显微硬度、摩擦学性能和耐腐蚀性的影响。随着NbC合成量的增加，相组成没有明显变化。随着x的增加，结构变化包括NbC颗粒团聚、粗化、FCC相密度变化和WCp成核。在x = 20 wt%时，结构得到最佳细化，分布均匀。WCp的形核逐渐由颗粒晶界偏析转变为接近NbC的非均质形核。热力学计算揭示了WCp-NbC界面的梯度层状结构。当NbC为20 wt%时，显微硬度达到57.63 HRC，约为基体硬度的3.6倍。涂层表现出磨蚀性、粘结性和氧化性磨损。该涂层在x = 20 wt%时表现出最佳的耐腐蚀性。研究结果为激光熔覆制备高性能MMC涂层提供了理论依据。

The microstructure and properties of reinforced Ni-20WC coatings by the laser-cladding in-situ synthesis of xNbC

Laser cladding was used to fabricate in-situ synthesized xNbC, enhancing the Ni-20 W C coating on AISI1045 steel. The study examined the effects of NbC synthesis on the microstructure, microhardness, tribological properties, and corrosion resistance of metal-matrix composite (MMC) coatings. No significant changes were observed in phase composition with increasing NbC synthesis. As x increased, structural changes included NbC particle agglomeration, roughening, FCC phase density variations, and WCp nucleation. At x = 20 wt%, the structure was optimally refined with even distribution. The nucleation of WCp gradually changed from granular grain boundary segregation to heterogeneous nucleation close to NbC. Thermodynamic calculations revealed a gradient-layered structure at the WCp-NbC interface. The microhardness peaked at 57.63 HRC with 20 wt% NbC, approximately 3.6 times the matrix hardness. The coatings exhibited abrasive, adhesive, and oxidative wear. The coating exhibits the best corrosion resistance at x = 20 wt%. The results provide a theoretical basis for high-performance MMC coatings via laser cladding.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
