Description

复合材料刀片
技术领域
本实用新型涉及一种刀片，尤其涉及由两种或两种以上不同材料复合而成的刀片。
背景技术
普通的刀具的刀片体由单一材料构成，例如钢刀、不锈钢刀、陶瓷刀等。传统金属铸制的刀具，因其表面有无数毛细孔，因此料理食材时会有汤汁残留于毛细孔中，且料理食材时金属制的刀具会有微量的金属元素，形成异味或金属味，并且金属刀(包括不锈钢刀)都会发生不同程度的生锈。
新型陶瓷刀具材料由于具有高硬度、高耐磨性、高耐热性和高的化学稳定性等独特的性能，近些年来在刀具行业得到较为广泛的应用。陶瓷刀是使用精密陶瓷高温高压烧制而成的刀具。陶瓷刀具有耐磨、高密度、高硬度、无毛细孔、不会藏污纳垢、不会生锈、切食物无金属味残留、轻薄锐利、易拿易切、清洗容易、外观美丽等优点，具有许多金属制刀具无法取代的特性。
尽管陶瓷刀具有上述众多金属刀无法比拟的优点，但也具有其不足，例如韧性较低、性脆易断、不能承受较大的冲击、使用时易发生破损、可靠性较差等。
目前国内外有研究用多种增韧机制来提高陶瓷刀具韧性的，但效果不十分理想。如采用颗粒弥散增韧，其增韧幅度十分有限；采用相变增韧，陶瓷刀具的增韧效果随切削温度的升高而下降，且韧性增加的同时，强度降低；采用晶须增韧，能显著提高陶瓷刀具材料的断裂韧性，但价格昂贵，使用成本高。此外，也有利用CVD(ChemicalVapor Deposition，化学气相淀积)涂层设备在硬质合金上涂一层陶瓷涂层，由于涂层很薄，容易磨损；因界面结合强度低也易产生涂层剥落，并且设备投资大，工艺比较复杂。
实用新型内容
本实用新型所要解决的技术问题是提供一种制造使用成本低且能有效改善陶瓷刀具材料的断裂韧性和抗弯强度的复合材料刀片。
为解决上述技术问题，本实用新型采用的技术方案是：提供一种复合材料刀片，包括由陶瓷制成的第一部分以及由韧度大于陶瓷的材料制成的第二部分，所述第一部分与第二部分相互接合在一起。
根据本实用新型的复合材料刀片，所述第一部分与第二部分通过粘接、焊接、机械夹固、铆接、喷涂、热压烧结或物理气相淀积(真空镀膜)等方式接合在一起。所述焊接的方式可以包括激光焊接或超声波焊接等；所述粘接的方式中，可采用中温固化的胶膜等结构粘接剂进行粘接。
根据本实用新型的复合材料刀片，所述刀片的刀柄部表面还设置有金属加固层。
根据本实用新型的复合材料刀片，所述刀片可以采用两层结构，其中第一部分构成包含刀刃部的底层，第二部分构成顶层。第二部分可以由金属、塑料或其它增韧材料制成。
根据本实用新型的复合材料刀片，所述刀片也可以为三层结构，其中第一部分构成包含刀刃部的中间层，第二部分构成上层和下层。第二部分由金属、塑料或其它增韧材料制成。
根据本实用新型的复合材料刀片，所述刀片还可以为单层结构，其中第一部分为刀刃部，第二部分为金属或塑料制成的刀背部，所述刀刃部与刀背部沿接合线接合为一体。
本实用新型的复合材料刀片是由陶瓷材料与金属、塑料等增韧材料通过粘接、焊接、机械夹固、喷涂、热压烧结或物理气相淀积等方式接合在一起，陶瓷材料与增韧材料之间接合牢固、不易脱落，增韧材料可以提高刀片的抗冲击性和抗跌落性，陶瓷材料使刀片具有良好的切削性能，从而在同一把刀上综合体现出两种材料的优点，并且与其它陶瓷刀具增韧和改性方式相比，具有工艺简单、制造使用成本低等优点。

实施例八
参见图9，本实施例的复合材料刀片由刀刃部27、刀背部28和刀柄部29构成，由于刀柄部29通常为刀片最易断的部位，因此可以在刀柄部29表面设置一金属加固层30，金属加固层30与刀柄部29之间通过粘接剂粘接，以提高其抗跌韧性。
实施例九
