Description
技术领域technical field
本发明属于非金属硬脆材料的切削刀具技术领域，具体涉及一种金刚石刀具，同时还涉及一种金刚石刀具的制备方法及使用上述金刚石刀具的金刚石复合刀具。The invention belongs to the technical field of cutting tools for non-metal hard and brittle materials, and specifically relates to a diamond tool, and also relates to a preparation method of the diamond tool and a diamond composite tool using the diamond tool.
背景技术Background technique
金刚石具有极高的硬度、高导热性和低热膨胀系数，是制造切削和磨削工具的最佳材料，应用广泛。采用金刚石制成的金刚石刀具具有高硬度和耐磨性、低摩擦系数、高弹性模量、高热导、低热膨胀系数，以及与非铁金属亲和力小等优点，可以用于非金属硬脆材料如石墨、高耐磨材料、复合材料、高硅铝合金及其它韧性有色金属材料的精密加工。但是，金刚石本身既硬又脆，单独制作刀具难度大、成本高，必须与其它韧性较好的材料连接制成刀具使用。Diamond has extremely high hardness, high thermal conductivity and low thermal expansion coefficient. It is the best material for making cutting and grinding tools and is widely used. Diamond tools made of diamond have the advantages of high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals, and can be used for non-metallic hard and brittle materials such as Precision machining of graphite, high wear-resistant materials, composite materials, high-silicon aluminum alloys and other tough non-ferrous metal materials. However, diamond itself is hard and brittle, so it is difficult and costly to make knives alone, and must be connected with other materials with better toughness to make knives.
现有的金刚石工具根据制备工艺的不同可分为电镀金刚石工具、孕镶烧结金刚石工具以及钎焊金刚石工具。电镀金刚石工具中，金刚石仅能用镍金属作机械包镶，故易于脱落；在孕镶烧结金刚石工具中，金刚石与粉料也很难实现冶金结合。钎焊金刚石工具采用金刚石表面金属化技术，以活性钎料或镍基钎料将金刚石焊接在工具胎体(刀体)上，通过强碳化物形成元素或合金，使金刚石与工具胎体(刀体)实现冶金化学结合。但是，上述金刚石工具中金刚石在刀体表面都是随机分布的，金刚石的无序排列和不规则分布，不能充分有效地利用金刚石的切割性能，金刚石刀具的切削效率低、金刚石的利用率低，造成了金刚石资源的浪费。Existing diamond tools can be classified into electroplated diamond tools, impregnated sintered diamond tools and brazed diamond tools according to different manufacturing processes. In electroplated diamond tools, diamond can only be mechanically inlaid with nickel metal, so it is easy to fall off; in impregnated sintered diamond tools, it is difficult to achieve metallurgical bonding between diamond and powder. Brazed diamond tools use diamond surface metallization technology to weld diamond on the tool matrix (cutter body) with active solder or nickel-based solder, and form elements or alloys through strong carbides to make diamond and tool matrix (knife body) body) to achieve metallurgical chemical combination. However, in the above-mentioned diamond tools, the diamonds are randomly distributed on the surface of the cutter body, and the disordered arrangement and irregular distribution of the diamonds cannot fully and effectively utilize the cutting performance of the diamonds. The cutting efficiency of the diamond tools is low, and the utilization rate of the diamonds is low. Caused the waste of diamond resources.
