一种耐磨疏水纳米复合薄膜及其制备方法

Abstract

一种耐磨疏水纳米复合薄膜及其制备方法,属于金属表面处理和改性技术领域。该复合薄膜是以高速钢、或钛合金、或硬质合金、或纯金属为基体,在其表面依次制备有纯金属薄膜、带有微结构形貌的纳米复合薄膜。该方法首先利用电弧离子镀在基体材料表面沉积一层力学性能优异的纳米复合硬质薄膜,然后再利用超快激光加工技术在薄膜表面产生微纳双重结构,制备成了兼具优良力学性能和一定疏水性能的表面薄膜。本发明制备的薄膜保留了纳米复合硬质薄膜优良的力学性能:表面硬度高、韧性、耐磨性、抗划伤性能强,通过构造薄膜表面的微结构形貌使薄膜具备了一定的疏水性能。该制备方法设备相对简单、成本低、能耗低、无污染,能够实现高效的绿色制造。
The invention relates to a wear-resistant hydrophobic nano composite film and a preparation method thereof, belonging to the technical field of metal surface treatment and modification. The composite film is based on high-speed steel, or titanium alloy, or hard alloy, or pure metal, and a pure metal film and a microstructure nano composite film are sequentially prepared on the base surface. The preparation method comprises the following steps: depositing a nano composite hard film with excellent mechanical properties on the base material surface by arc ion plating, and generating a micro/nano dual structure on the film surface by an ultra-fast laser processing technique to obtain the surface film with favorable mechanical properties and certain hydrophobicity. The film maintains excellent mechanical properties of the nano composite hard film: high surface hardness, high toughness, high wearability and high scratch resistance; and the microstructure on the film surface is constructed, so that the film has certain hydrophobicity. The preparation method has the advantages of simpler equipment, low cost, low energy consumption and no pollution, and can implement efficient green manufacturing.
