技术领域technical field
本发明涉及石材及玻璃切削加工工具材料，具体是铜基粉末烧结金刚石复合材料及其制备方法。The invention relates to a stone and glass cutting tool material, in particular to a copper-based powder sintered diamond composite material and a preparation method thereof.
背景技术Background technique
金刚石锯片是陶瓷、水晶、玻璃、石英、宝石、硬质合金、半导体、磁性材料等加工业的重要工具，目前金刚石锯片的基体材料普遍采用酚醛树脂。树脂锯片抗弯强度、硬度、冲击韧性低、孔隙率高，与金刚石润湿性差，金刚石脱落度较大，致使金刚石的利用率较低。近来，新发展的铜铁基粉末烧结金刚石复合材料在水冷却条件下锯切时腐蚀产物多，对产品及加工现场污染严重。Diamond saw blades are important tools for processing industries such as ceramics, crystal, glass, quartz, gemstones, hard alloys, semiconductors, and magnetic materials. At present, phenolic resin is generally used as the base material of diamond saw blades. Resin saw blades have low bending strength, hardness, impact toughness, high porosity, poor wettability with diamond, and high diamond shedding, resulting in low diamond utilization. Recently, the newly developed copper-iron-based powder sintered diamond composite material has many corrosion products when sawing under water cooling conditions, which seriously pollutes the product and the processing site.
发明内容Contents of the invention
本发明的目的是制备导热、耐磨、耐腐蚀性良好的铜基粉末烧结金刚石复合锯片基体材料，提高锯片抗弯强度、硬度、冲击韧性和耐腐蚀性，降低孔隙率，提高金刚石利用率。The purpose of the present invention is to prepare a copper-based powder sintered diamond composite saw blade matrix material with good thermal conductivity, wear resistance and corrosion resistance, improve the bending strength, hardness, impact toughness and corrosion resistance of the saw blade, reduce porosity, and improve diamond utilization. Rate.
本发明是铜基粉末烧结金刚石复合材料及其制备方法，按重量百分比计量铜基粉末基体材料的组分为：Cu 58.00～63.00％，Ni 15.50～18.50％，Co14.00～18.00％，Fe 2.00～5.00％，Cr 1.50～3.50％，Sn 1.50～3.50％，其它杂质≤1％；金刚石粉末按以上基体材料总重量的3.60～5.10％配料。The present invention is a copper-based powder sintered diamond composite material and a preparation method thereof. The components of the copper-based powder matrix material measured by weight percentage are: Cu 58.00-63.00%, Ni 15.50-18.50%, Co 14.00-18.00%, Fe 2.00 ～5.00%, Cr 1.50～3.50%, Sn 1.50～3.50%, other impurities ≤1%; diamond powder is compounded according to 3.60～5.10% of the total weight of the above matrix materials.
铜基粉末烧结金刚石复合材料制备方法，按上述铜基粉末基体材料的组分和金刚石粉末组分进行配料，在转速为200r/min、球料比为5∶1的工况下进行球磨混料，时间持续20分钟，按产品重量要求称料、装入压模中用压力机压制成型，然后在真空感应烧结压机中用石墨模具加压，压力范围为2～3.5Mpa，烧结成成形材料，烧结温度为650～840℃，保温6～12分钟。The preparation method of copper-based powder sintered diamond composite material is carried out according to the above-mentioned components of copper-based powder matrix material and diamond powder components, and ball milling is carried out under the working conditions of 200r/min and a ball-to-material ratio of 5:1. , the time lasts for 20 minutes, weigh the material according to the product weight requirements, put it into the compression mold and press it with a press, and then press it with a graphite mold in a vacuum induction sintering press. The pressure range is 2 to 3.5Mpa, and sintered into a shaped material , the sintering temperature is 650-840°C, and the temperature is kept for 6-12 minutes.
本发明的有益效果为：Cu、Ni、Sn是烧结基体主要组元，起支撑作用，决定材料的硬度、强度等机械性能。烧结过程中Sn和Cu、Ni相互扩散，形成α固溶体，材料的硬度有所加强；Sn和Cu、Ni极易相互扩散，并且随着Sn含量的增加，固溶度增大，材料的硬度增加；当Cu的含量大于55％时，Cu基烧结体的组织形成大量的能填孔隙的轻质金属—富铜ε相，材料的硬度得到提高；Ni、Fe、Cr在烧结过程中形成了Fe7Ni3、CrFe4、FeCrNi等金属间化合物，对烧结基体起到了弥散强硬化的作用；Co颗粒的强度和硬度都高于基体合金，因此均匀分布于基体中的Co颗粒能够起到颗粒强化的作用。金刚石主要起切割作用，金刚石与基体材料中的其它成分不起任何化学反应，但能被基体金属Cu、Ni润湿。铜铁基粉末烧结金刚石复合材料的硬度HB≥160，性能稳定。The beneficial effects of the invention are: Cu, Ni and Sn are the main components of the sintered matrix, which play a supporting role and determine the mechanical properties such as hardness and strength of the material. During the sintering process, Sn, Cu, and Ni diffuse each other to form α solid solution, and the hardness of the material is enhanced; Sn, Cu, and Ni are very easy to interdiffuse, and with the increase of Sn content, the solid solubility increases, and the hardness of the material increases ; When the Cu content is greater than 55%, the structure of the Cu-based sintered body forms a large number of light metals that can fill the pores—copper-rich ε phase, and the hardness of the material is improved; Ni, Fe, and Cr form Fe during the sintering process. 7 Ni 3 , CrFe 4 , FeCrNi and other intermetallic compounds play a role of dispersion strengthening hardening on the sintered matrix; the strength and hardness of Co particles are higher than that of the matrix alloy, so the Co particles uniformly distributed in the matrix can play a role in particle strengthening. role. Diamond mainly plays the role of cutting. Diamond does not have any chemical reaction with other components in the matrix material, but it can be wetted by the matrix metal Cu and Ni. The hardness of the copper-iron-based powder sintered diamond composite material is HB≥160, and its performance is stable.
