Description
技术领域
本发明涉及多晶金刚石(PCD)主体和特别地但不唯一地用于钻入地中或破裂岩石的包括PCD主体的工具或工具元件。
背景技术
含有多晶金刚石(PCD)的工具元件广泛用于各种工具中进行切削、机加工、钻削或破裂硬质或研磨性材料如岩石、金属、陶瓷、复合体和含木材料。PCD含有大量基本上共生的金刚石颗粒并形成骨架体,其限定金刚石颗粒之间的间隙。PCD材料含有至少约80vol(体积)%的金刚石,并且可通过在烧结助剂,也称为金刚石催化剂材料存在的情况下,使金刚石颗粒聚集体经受高于约5Gpa的超高压力和至少约1200°C的温度而制备。金刚石催化剂材料可理解为在金刚石比石墨更加热力学稳定的压力和温度条件下能促进金刚石颗粒直接共生的材料。一些金刚石催化剂材料可在环境压力,特别是在升高的温度下促进金刚石向石墨的转化。金刚石催化剂材料的实例为钴、铁、镍和包括这些中任意几种的特定合金。PCD可以在烧结钴碳化钨基材上形成,该基材可提供PCD的钴催化剂材料的来源。PCD材料中的间隙可以至少部分用催化剂材料进行填充。含有作为填充材料的特定金刚石催化剂材料的PCD的缺点可能是在升高温度下其耐磨性下降。
美国专利No.6,651,757公开了一种嵌件,其包括具有接触部分的暴露的表面,所述接触部分包括PCD材料。在优选的实施方案中,被称为“第二相”材料的附加材料被加入金刚石晶体中,从而降低晶体间的结合。第二相材料可以是金属如W、V或Ti。
美国专利No.7,553,350公开了一种高强度和高耐磨的烧结金刚石物体,其包括具有至多2微米的平均颗粒尺寸的烧结金刚石颗粒和作为剩余部分的粘结剂相。粘结剂相含有含量为至少0.5%质量且小于50%质量的至少一种选自由钛、锆、铪、钒、铌、钽、铬和钼组成的组的元素,并含有含量为至少50%质量且小于99.5%质量的钴。在一个实施方案中,烧结金刚石物体的选自由Ti、Zr、Hf、V、Nb、Ta、Cr和Mo组成的组的至少一种元素为Ti,且在粘结剂相中Ti的含量优选为至少0.5%质量且小于20%质量。添加剂的目的是抑制细小金刚石颗粒的异常生长。PCD材料具体用于由车刀代表的切削工具、铣削工具、端铣刀、耐磨工具、拉模、机床和应用于电子材料如电子零件中。
特别地在切削或钻削进岩石的应用中,存在对具有增强的抗冲击性和良好耐磨性的PCD材料的需求。

实施方案可包括精细分散在填充材料中的混合碳化物微粒,所述混合碳化物具有(Ti,W,V)xCy的化学式。例如,PCD主体的实施方案可包括分散在填充材料中的含有W0.37V0.63Cx或W0.40Ti0.37V0.23Cx或两者的微粒。在一些实施方案中,η相微粒可以分散在填充材料中,所述η相具有化学式Coz(Ti,W,V)xCy。在一些实施方案中,z可以为至少约3且至多约6,在一些实施方案中,x可以为至少约3且至多约6。在一个实施方案中,y可以为约1。例如,PCD主体的实施方案可包括分散在填充材料中的含有Co3W3C或Co6W6C的η相微粒。
在一些实施方案中,微粒相以具有至少约100nm或至少约200nm的平均尺寸的微粒形式存在;在一些实施方案中,微粒相的微粒具有至多约1,000nm的平均尺寸。在一个实施方案中,微粒相中至多约10%或至多5%的微粒可具有比约1,000nm更大的尺寸。
在一些实施方案中,金刚石颗粒具有大于2微米或至少约3微米的平均尺寸。在一些实施方案中,金刚石颗粒具有至多约10微米或甚至至多约5微米的平均尺寸。
在一些实施方案中,PCD主体具有至少约62%或至少约64%的金刚石颗粒的连续性。在一些实施方案中,超硬颗粒的连续性为至多约92%,至多约85%或甚至至多约80%。
在一些实施方案中,PCD主体含有至少约85vol(体积)%或至少约88vol%的金刚石,在一个实施方案中,PCD主体含有至多约99vol%的金刚石。

实施方案可包括使PCD主体在至少约500°C,至少约600°C或至少约650°C的温度下经受至少约30分钟的热处理。在一些实施方案中,温度为至多约850°C,至多约800°C或至多约750°C。在一些实施方案中,PCD主体可以经受至多约120分钟或至多约60分钟的热处理。在一个实施方案中,PCD主体在真空中经受热处理。
特别地当用于岩石切削时,一些实施方案可具有增强的耐磨损性和延长的使用寿命的优点。平均金刚石颗粒尺寸大于约2微米的实施方案一般可具有更高的强度和抗断裂性。

图2示出PCD刀具嵌件的实施方案的示意性横截面图以及示出PCD材料的实施方案的微结构的示意性展开图。
在所有附图中相同的参考标记指的是相同的各个特征。
具体实施方式
如本文所用,“PCD材料”为含有大量金刚石颗粒的材料,其大部分是彼此直接地相互结合,其中金刚石的含量为材料的至少约80vol%。在PCD材料的一个实施方案中,金刚石颗粒之间的间隙可以至少部分地用含有金刚石催化剂的粘结剂材料填充。
如本文所用,“金刚石催化剂材料”是在金刚石比石墨在热力学上更加稳定的压力和温度下,能够促进金刚石生长或金刚石颗粒之间直接的金刚石与金刚石相互生长的材料。
图1示出了用于镗削入地中的钻头(未示出)的PCD刀具嵌件10的实施方案,所述嵌件10包括结合至烧结碳化钨基材30的PCD主体20。
图2示出了用于镗削入地中的钻头(未示出)的PCD刀具嵌件10的实施方案,所述嵌件10包括结合至烧结碳化钨基材30的PCD主体20。PCD主体20的微结构21包括相互结合的金刚石颗粒22的骨架体,所述金刚石颗粒之间限定有间隙24,所述间隙24至少部分填充含有钴的填充材料。间隙24中的填充材料可含有Ti、W和V,填充材料中Ti的含量为填充材料的约1wt%,填充材料中V的含量为填充材料的约2wt%,且填充材料中W的含量为填充材料的约20wt%。

在一个实施方案中,在至少约500°C且至多约850°C的温度下热处理所述PCD主体。尽管不希望被具体理论所束缚,但是热处理可促进混合碳化物η相,具体地如Coz(Ti,W,V)xCy的相的形成。
如本文所用,颗粒的“当量圆直径”(ECD)为具有与穿过颗粒的截面相同面积的圆的直径。借助于穿过所述主体的截面或主体表面的成像分析,可以对单独的、未结合的颗粒或对在主体内结合在一起的颗粒进行ECD尺寸分布和多个颗粒平均尺寸的测量。
如本文所用,大量颗粒的“多峰尺寸分布”包括多于一个峰,或可以被分解为多于一个尺寸分布的叠加,每个尺寸分布具有一个单独的峰,每个峰对应于各自的“模式”。多峰多晶主体通常通过提供多个颗粒的多于一个的来源,每个来源含有基本上不同平均尺寸的颗粒,并将颗粒或来自所述来源的颗粒混合在一起而制备。
如本文所用,“颗粒连续性”κ是对颗粒与颗粒的接触或结合,或者接触与结合两者的组合的测量,并且根据下面的公式计算,该公式使用多晶超硬材料的抛光截面的成像分析获得的数据:
κ=100×[2×(δ-β)]/[(2×(δ-β))+δ],其中δ为超硬颗粒的周长,而β为粘结剂的周长。
超硬颗粒的周长是与其他超硬颗粒接触的超硬颗粒表面的分数。对于给定的体积,其被测量为颗粒与颗粒接触的总面积除以超硬颗粒的总表面面积。粘结剂周长是不与其他超硬颗粒接触的超硬颗粒表面的分数。实际上,连续性的测量借助于抛光截面表面的成像分析完成,并且对通过位于所分析截面内的所有颗粒与颗粒界面上所有点的线的组合长度进行合计,以确定超硬颗粒的周长,并且类似地用于粘结剂周长。
为了获得多晶结构内颗粒或间隙尺寸的测量,可以使用已知为“当量圆直径”的方法。在该方法中,使用PCD材料的抛光表面的扫描电子显微照片(SEM)图像。放大率和对比度对于在图像内识别至少几百个金刚石颗粒应该是足够的。金刚石颗粒可以与图像内的金属相区分,且可以借助于常用图像分析软件来确定每个单独金刚石颗粒的尺寸当量圆。这些圆的分布收集后经统计学评估。无论本文的PCD材料内的金刚石平均颗粒尺寸指的是哪里,应理解其指平均当量圆直径。一般地,该测量的标准偏差越大,结构的均匀性越小。
PCD切削元件的实施方案也可以用作计量剪切器(gauge trimmer),并可用在其他种类的钻地工具。例如,切削元件的实施方案也可以用在牙轮钻头的锥体上、铰床、磨机、双心钻头、偏心钻头、取心钻头和包括固定刀具和滚动牙轮两者的所谓混合钻头上。
用于图像分析的图像可借助于使用背反射电子信号取得的扫描电子显微照片(SEM)而获得。相比之下,光学显微照片一般不具有充足的聚焦深度且不能给出基本上不同的对比度。足够的对比度对于连续性的测量是重要的,因为可以根据灰度的对比度来识别颗粒间的边界。
借助于图像分析软件可从SEM图像中确定连续性。具体地,可以使用商标名analySIS Pro,来源于软件成像***有限公司(Soft ImagingGmbH)(奥林巴斯软件成像方案有限公司,Olympus Soft Imaging Solutions GmbH的商标)的软件。该软件具有“分离颗粒”过滤器,如果有待分离的结构为紧密的结构,则该过滤器根据操作手册只提供满意的结果。因此,在应用该过滤器前填满任何孔隙是重要的。例如,可以使用“Morph.Close”指令或从“Fillhole”模块获得帮助。除了该过滤器之外,“分离器(Separator)”为另一个可获得的强有力的用于颗粒分离的过滤器。根据操作手册,该分离器也可以用于颜色-和灰度-值图像。
尽管不希望被任何具体理论束缚,但在填充材料中Ti和金属M附加物的组合可导致在一些实施方案中的填充材料内含有Ti、M或W,或这些元素特定组合的微粒非常精细的分散。在一些实施方案中,这可以对所使用的PCD材料中裂纹产生和扩展的能量具有更好的分散效果,从而导致PCD材料的改变的耐磨特性和增强的抗冲击性和抗断裂性,因此在一些应用中延长了使用寿命。
尽管不希望被任何具体理论束缚,但以各自碳化物混合物的形式引入Ti或金属M或两者的优点可起因于以下事实,即限制或避免了O的共同引入,因为Ti的氧化物形式非常稳定且氧气对金刚石颗粒的烧结以形成PCD会产生不良影响。
现在参考下面的不旨在作为限制的实施例,对实施方案进行更加详细的描述。
实施例1
通过将两种不同来源的金刚石颗粒混合在一起而制备了双峰混合的金刚石粉末,第一种来源中的金刚石颗粒的平均尺寸为约2微米,第二种来源中的为约5微米,以形成金刚石颗粒的聚集混合体。混合的金刚石颗粒在酸中处理,以去除可能存在的表面杂质。然后使用行星式球磨,通过将VC微粒和TiC微粒与金刚石粉末混合而将碳化钒和碳化钛引入到金刚石粉末混合物中。TiC微粒的平均尺寸为约3微米,VC微粒的平均尺寸为约4微米。粉末中TiC微粒的含量为金刚石粉末的约0.5wt%,VC微粒的含量为金刚石粉末的约0.5wt%。
将包覆的金刚石粉末的聚集体放在烧结钴WC基材上并封装,以形成预烧结组件,然后所述预烧结组件在真空中排出气体,以便从金刚石颗粒中去除表面杂质。使预烧结组件在超高压力炉中经受约6.5GPa的压力和约1,550°C的温度,从而烧结金刚石颗粒并形成含有与碳化物基材整体形成的PCD材料层的PCD坯块(compact)。在烧结过程期间,来自基材并含有溶解的W或WC或两者的熔化钴,在溶液中渗入到金刚石颗粒的聚集体中。PCD材料的图像分析显示金刚石含量为约89vol%,金刚石颗粒的连续性为约62%,按照当量圆直径的烧结金刚石颗粒的平均尺寸为约3.8微米。
对PCD坯块进行加工,以形成试验PCD刀具嵌件用于进行磨损试验。磨损试验涉及在垂直刀架磨削装置中使用该嵌件,以切削一段长度的含有花岗岩的工件材料,直到由于断裂或过度磨损而使嵌件失效。在嵌件被认为已经失效之前,工件被切削通过的距离可以是期望的使用工作寿命的标示。为了比较,除了没有引入V和Ti之外,采用与试验刀片相同的方式制备对照PCD刀片嵌件。使用试验嵌件获得的切削距离几乎是使用对照嵌件获得的切削距离的两倍,并且在试验嵌件上的磨痕比在对照嵌件上明显磨痕少约30%。
实施例2
如实施例2所述制备和测试试验PCD刀具嵌件和对照PCD刀具,不同之处在于在烧结前粉末中TiC微粒的含量为金刚石粉末的约1.5wt%,且VC微粒的含量为金刚石粉末的约1.5wt%。使用试验嵌件获得的切削距离比使用对照嵌件获得的切削距离长约40%,并且在试验嵌件上的磨痕为在对照嵌件上明显磨痕的约一半。
实施例3
通过将三种不同来源的金刚石颗粒混合在一起而制备三峰混合金刚石粉末,第一种来源中的金刚石颗粒的平均尺寸为约0.8微米,第二种来源中的金刚石颗粒的平均尺寸为约2微米,第三种来源中的金刚石颗粒的平均尺寸为约10微米,以形成金刚石颗粒的聚集混合体。混合的金刚石颗粒在酸中处理,以去除可能存在的表面杂质。然后使用行星式球磨,通过将VC微粒和TiC微粒与金刚石粉末混合而将碳化钒和碳化钛引入到金刚石粉末混合物中。TiC微粒的平均尺寸为约3微米,且VC微粒的平均尺寸为约4微米。粉末中TiC微粒的含量为金刚石粉末的约1.5wt%,VC微粒的含量为金刚石粉末的约1.5wt%。
将包覆的金刚石粉末的聚集体放在烧结钴WC基材上并封装,以形成预烧结组件,然后所述预烧结组件在真空中排出气体,以便从金刚石颗粒中去除表面杂质。使预烧结组件在超高压力炉中经受约6.5GPa的压力和约1,550°C的温度,从而烧结金刚石颗粒并形成含有与碳化物基材整体形成的PCD材料层的PCD坯块。在烧结过程期间,来自基材并含有溶解的W或WC或两者的熔化钴,在溶液中渗入到金刚石颗粒的聚集体中。按照当量圆直径的烧结金刚石颗粒的平均尺寸为约6微米。
对PCD坯块进行加工,以形成试验PCD刀具嵌件用于进行磨损试验。磨损试验涉及在垂直刀架磨削装置中使用所述嵌件,以切削一段长度的含有花岗岩的工件材料,直到由于断裂或过度磨损而使嵌件失效。在嵌件被认为已经失效之前,工件被切削通过的距离可以是期望的使用工作寿命的标示。为了比较,除了没有引入V和Ti之外,采用与试验刀片相同的方式制备对照PCD刀具嵌件。使用试验嵌件获得的切削距离大于使用对照嵌件获得的切削距离的两倍,尽管在试验嵌件上的磨痕几乎是在对照嵌件上明显磨痕的两倍。
实施例4
通过将两个种同来源的金刚石颗粒混合在一起而制备双峰混合金刚石粉末,每种来源中的金刚石颗粒的平均尺寸分别为约2微米和5微米,以形成具有约3.8微米的平均尺寸的金刚石颗粒的聚集混合体。将混合的金刚石颗粒在酸中处理,以去除可能存在的表面杂质。
然后通过将V沉积在悬浮液中的金刚石颗粒上而将碳化钒引入到金刚石粉末混合物中。将金刚石粉末悬浮在乙醇和三异丙氧化钒(vanadium tri-isopropoxide)的前驱体(一种有机化合物)中,然后以控制的逐滴的方式将去离子水输入到悬浮液中。计算前驱体的浓度以获得沉积在金刚石颗粒上的VC的具体浓度。在经过约400分钟时间后,含钒的有机前驱体转化为沉积在金刚石颗粒上的五氧化二钒(V2O5)化合物。然后蒸发乙醇并且将包覆的金刚石在约100°C下在真空炉中干燥过夜。然后通过已知方法将含有CoCO3的另外的涂层沉积在金刚石颗粒上,以形成含有金刚石颗粒的金刚石粉末,该金刚石颗粒具有沉积在颗粒表面上的V2O5和CoCO3微结构。然后使该粉末在氢气中经受热处理,以将五氧化二钒还原为碳化钒并将CoCO3还原为Co。XRD分析示出VC和Co存在于金刚石颗粒表面上,并且SEM分析示出这些是以精细分散微粒的形式分布在金刚石颗粒表面上。然后将TiC微粒与包覆的金刚石粉末混合,以形成混合粉末,其中TiC的含量为金刚石粉末的约1.5wt%,VC的含量为金刚石粉末的约1.5wt%。
将混合粉末的聚集体放在烧结钴WC基材上并封装,以形成预烧结组件,然后所述预烧结组件在真空中排出气体,以便从金刚石颗粒中去除表面杂质。然后使预烧结组件在超高压力炉中经受约6.5GPa的压力和约1,550°C的温度,从而烧结金刚石颗粒并形成含有与碳化物基材整体形成的PCD材料层的PCD坯块。在烧结过程期间,将来自基材并在溶液中含有溶解的W或WC或两者的熔化钴渗入到金刚石颗粒的聚集体中。
