摘要: 针对非润湿型复合体系氧化锆增韧氧化铝(ZrO2 toughened Al2O3,ZTA)陶瓷增强高铬铸铁(High chromium cast iron,HCCI)材料界面相容性差、材料性能提升不足的问题,采用液态模锻技术在压力作用下实现ZTA与HCCI的良好结合。研究液锻压力(0 MPa、40 MPa、70 MPa和100 MPa)对界面结合状态、界面结合率以及界面结合强度的影响,探讨ZTA/HCCI界面的形成过程与结合机制。结果表明:对于确定的陶瓷表面形貌(Sa=2.046μm),随着制备压力由40 MPa提高到100 MPa,陶瓷与金属的结合率由37.71%提高到98.89%,啮合强度由16.73 MPa增加到24.91 MPa,增幅为48.9%。此外,当制备压力由40 MPa提高到70 MPa以及由70 MPa提高到100 MPa时,啮合强度的增幅在变缓(由30.1%降至14.5%)。说明虽然压力的增加可以提高界面强度,但当制备压力增大到一定值后,陶瓷与金属几乎实现完全结合,结合强度将基本不再变化。界面结合强度的提高可归因于陶瓷与金属结合面空隙在压力作用下由大变小的过程,即结合率的提高。ZTA/HCCI界面在压力作用下经历接触阶段、初步结合阶段、强化结合阶段以及几乎完全结合阶段,从而实现微观尺度上的机械啮合,获得高结合强度。为解决非润湿型陶瓷/金属复合材料的界面结合问题提供新的思路与方法,丰富此类复合材料的界面控制理论,为金属基复合材料的工业化应用奠定理论基础。

Abstract: To address the issues of poor interfacial compatibility and inadequate enhancement of materials performance in non-wetting system ZrO2 toughened Al2O3(ZTA) ceramic-reinforced high chromium cast iron(HCCI) composites, liquid forging technology is proposed for establishing reliable bonding between ZTA and HCCI under pressure. The effects of varying liquid forging pressure(0 MPa, 40 MPa, 70 MPa and 100 MPa) on the interfacial bonding state, bonding rate and shear strength are systematically studied. The formation process and bonding mechanism of the ZTA/HCCI interface are discussed. The results indicate that, for the determined ceramic surface morphology(Sa=2.046 μm), the ceramic-to-metal bonding rate increases from 37.71% to 98.89%, and the bonding strength rises from 16.73 MPa to 24.91 MPa(with an increase of 48.9%) as the preparation pressure increases from 40 MPa to 100 MPa. In addition, when the pressure rises from 40 MPa to 70 MPa and from 70 MPa to 100 MPa, the increase of bonding strength slows down from 30.1% to 14.5%. This indicates that although the increase in pressure can improve the bonding strength, after the pressure reaches a certain value, almost completely interfacial bonding between the ceramic and metal is attained, and the bonding strength basically remains unchanged. The enhancement of interfacial bonding strength can be attributed to the reduction of void size in the interface under pressure, which is also known as the increase in bonding rate. The ZTA/HCCI interface undergoes four phases under pressure:a contact phase, a preliminary bonding phase, a reinforced bonding phase, and an almost complete bonding phase, which achieves a mechanical engagement on the microscopic scale and results in a high bonding strength at the interface. A novel concepts and methodologies for solving the interface bonding problem of non-wetting ceramic/metal composites is proposed, enriches the interfacial control theory of such composites, and establishes a theoretical framework for the industrial application of metal matrix composites.
