    摘要:

    界面優(yōu)化是提高鋁基復(fù)合材料最為有效的手段。通過化學(xué)鍍工藝成功制備0.2 μm厚Ni-Co-P合金鍍層修飾的玄武巖纖維，并通過真空熱壓燒結(jié)工藝合成Ni-Co-P鍍層修飾玄武巖纖維增強(qiáng)2024Al復(fù)合材料（BF(Ni-Co-P)/Al）。探究了Ni-Co-P鍍層對(duì)BF(Ni-Co-P)/Al復(fù)合材料界面結(jié)構(gòu)及拉伸性能的影響機(jī)制。結(jié)果表明：復(fù)合材料中Ni-Co-P鍍層形成穩(wěn)定的Ni-Co-P中間層，不僅抑制了玄武巖纖維與鋁合金基體間的有害界面反應(yīng)，且優(yōu)化了二者間的結(jié)合強(qiáng)度。BF(Ni-Co-P)/Al復(fù)合材料密度及硬度明顯優(yōu)于BF/Al復(fù)合材料，且當(dāng)玄武巖纖維體積分?jǐn)?shù)為30vol%時(shí)，BF(Ni-Co-P)/Al復(fù)合材料屈服強(qiáng)度和抗拉伸強(qiáng)度分別為252和360 MPa，大幅高于未修飾纖維增強(qiáng)鋁基復(fù)合材料和鋁合金基體，并表現(xiàn)出漸進(jìn)累積失效的斷裂模式。

    Abstract:

    Interface optimization is an effective way to improve the performance of aluminum matrix composites. Basalt fibers (BF) modified by Ni-Co-P alloy coatings with about 0.2 μm in thickness were prepared by electroless plating firstly, and then Ni-Co-P coated basalt fibers reinforced 2024Al matrix composites (BF(Ni-Co-P)/Al) and uncoated basalt fibers reinforced 2024Al matrix composites (BF/Al) were fabricated by vacuum hot pressing sintering process. The effects of Ni-Co-P coatings on the interface microstructure and tensile properties of BF(Ni-Co-P)/Al composites were studied. The results show that stable Ni-Co-P intermediate layer is formed in BF(Ni-Co-P)/Al composites, which can not only restrain harmful interface reaction but also optimize the interface bonding state between matrix and basalt fiber. The density and hardness of BF(Ni-Co-P)/Al composites are superior to those of BF/Al composites, and yield strength (252 MPa) and ultimate tensile strength (360 MPa) of BF(Ni-Co-P)/Al composites with basalt fibers content of 30vol% have a significant improvement compared with those of BF/Al composites and 2024Al matrix, and the fracture mode is progressive accumulative failure.
