本發明係關於立方氮化硼(cBN)基複合物,其包括約30-65體積% cBN,約3-30體積%含鋯(Zr)化合物,約0-10體積%硼化鈷鎢(CoxWyBz),約2-30體積%氧化鋁(Al2O3),約0.5-10體積%硼化鎢,及小於或等於約5體積%氮化鋁(AlN)。

Description

立方氮化硼(cBN)基複合物,形成cBN基複合物之方法,及cBN基切割工具
本發明總體上係關於由立方氮化硼所形成之複合材料以及其製造及使用方法。詳言之,本發明係關於在難切割材料之機械加工中有用之複合材料。
在隨後的背景技術討論中參考了某些結構及/或方法。然而,以下參考文獻不應被解釋為承認此等結構及/或方法構成了先前技術。申請人明確保留證明該等結構及/或方法不符作為先前技術之權利。
立方氮化硼(cBN)為一種超硬材料,通常用於形成用於切割及/或機械加工應用之cBN基複合物。某些陶瓷材料,諸如氧化鋁(Al2O3)、氮化鈦(TiN)、氮化矽(Si3N4)等可與cBN摻合以改良耐化學磨損性。然而,該等陶瓷材料可能不具有足夠的硬度及/或耐熱性,而在機械加工硬質材料時無法達到最佳性能。例如,當切割或機械加工難切割材料,特別為耐熱超合金時,現有的cBN基複合物仍可能展現快速磨損、斷裂及/或失效。因此,需要一種用於切割及機械加工難切割材料之具有改良性質之更好的cBN基複合材料。
提供一種立方氮化硼(cBN)基複合物,其包括約30-65體積% cBN,約3-30體積%含鋯(Zr)化合物,約0-10體積%硼化鈷鎢(CoxWyBz),約2-30體積%氧化鋁(Al2O3),約0.5-10體積%硼化鎢,及小於或等於約5體積%氮化鋁(AlN)。
亦提供一種形成立方氮化硼(cBN)基複合物之方法。該方法包括混合用於形成cBN基複合物之cBN基製劑之粉末以形成第一混合物。cBN基複合物包括約30-65體積% cBN,約3-30體積%含鋯(Zr)化合物,約0-10體積%硼化鈷鎢(CoxWyBz),約2-30體積%氧化鋁(Al2O3),約0.5-10體積%硼化鎢,及小於或等於約5體積%氮化鋁(AlN)。該方法包括乾燥第一混合物以形成第二混合物,並且將第二混合物裝載至一或多個耐火模具中。該方法亦包括在高壓-高溫條件下燒結第二混合物。
進一步提供一種切割工具,其包括經燒結立方氮化硼(cBN)基粉壓坯。cBN基粉壓坯包括約30-65體積% cBN,約3-30體積%含鋯(Zr)化合物,約0-10體積%硼化鈷鎢(CoxWyBz),約2-30體積%氧化鋁(Al2O3),約0.5-10體積%硼化鎢,及小於或等於約5體積%氮化鋁(AlN)。經燒結粉壓坯是藉由以下所形成:混合用於形成經燒結cBN基粉壓坯之cBN基製劑之粉末以形成第一混合物,乾燥第一混合物以形成第二混合物,將第二混合物裝載至一或多個耐火模具中,及在高壓-高溫條件下燒結第二混合物以形成經燒結粉壓坯。

當結合附圖閱讀時,可更好地理解前述概述以及以下具體實例之詳細描述。應當理解,所描繪之具體實例不限於所示之精確配置及手段。
[圖1]顯示用於形成cBN基之經燒結粉壓坯或複合物之例示性過 程;[圖2]顯示XRD光譜,其顯示例示性之cBN基之經燒結粉壓坯或複合物中存在之相;[圖3]顯示XRD光譜,其顯示在另一例示性之cBN基之經燒結粉壓坯或複合物中存在之相;[圖4]顯示XRD光譜,其顯示在另一例示性之cBN基之經燒結粉壓坯或複合物中存在之相;及[圖5]顯示XRD光譜,其顯示在另一例示性之cBN基之經燒結粉壓坯或複合物中存在之相。
本發明係關於由立方氮化硼(cBN)所形成之複合物或經燒結粉壓坯以及其製造及使用方法。詳言之,本發明係關於改良的cBN基複合材料,其可用於切割及機械加工難切割材料,例如用於在高溫範圍內需要高強度之應用之超合金。例如,本文所揭示之cBN基複合材料(例如,經燒結粉壓坯)可用於切割及/或機械加工鎳基超合金(例如,英高鎳718、英高鎳625)、鈷基超合金(例如,合金188、海恩斯25、合金L605)、鐵基超合金(例如,A286)、或與此等超合金具有同等、較差或較好機械性質之任何材料。
本文所揭示之cBN基複合材料可包括(除其他改良外)更大的耐磨性、韌性、耐化學性、硬度及/或熱硬度。此等改良至少部分歸因於本文所揭示之比例之cBN、硼化鎢鈷(CoxWyBz)、硼化鎢(WB、W2B、W2B5或其組合)、氧化鋁(Al2O3)及含鋯(Zr)化合物(二氧化鋯、氮化鋯、碳化鋯、碳氮化鋯、二硼化鋯或其組合)之組合。本發明亦描述將cBN基製劑形成為經燒結粉壓坯之方法,該經燒結粉壓坯可用於切割或機械加工難切割材料。
考慮到前述,表1及2列出cBN基複合材料(例如,經燒結粉壓坯)之例示性組成。在圖1之流程圖中描繪用於形成cBN基複合材料之例示性過程。表1及2中所列之所有體積百分比(體積%)為以cBN基複合材料之總體積%計。

圖1描繪形成cBN基複合材料(例如,經燒結粉壓坯)之例示性過程100。例示性過程100包括混合cBN基製劑之粉末以形成第一混合物(步驟102)。cBN基製劑可包含或由一或多種粉末狀製劑組成,該粉末狀製劑包括例如包含或由cBN組成之粉末,包含或由鋯組成之粉末,諸如包含氧化鋯(可為立方相、單斜晶相及/或四方相)、ZrN、ZrC、ZrCN及/或ZrB2之粉末,包含或由鋁組成之粉末,諸如包含Al2O3及/或AlN之粉末,包含或由W組成之粉末,包含或由Co組成之粉末,包含或由B組成之粉末及其組合。步驟102包括提供可用於形成本文所揭示之cBN基複合材料之粉末(例如,表1及2中所示之組成)。粉末可為奈米及/或微米大小之粉末,例如,cBN基製劑之粉末之平均粒徑可在奈米(nm)或微米(μm)範圍內,即約100nm-6μm。步驟102可包括混合粉末以形成混合物或漿料。可使用任何合適的研磨或摻合技術(例如,磨碎機、球磨機等)來混合粉末。可將此等粉末研磨或摻入任何合適的溶劑中,例如乙醇、異丙醇、丙酮、甲醇、己烷、庚烷或其組合,以形成第一混合物。可根據用於獲得所需混合效果(例如,粉末分佈及均勻性)之研磨機之尺寸及/或類型來調節或調整研磨條件(例如,時間、每分鐘之旋轉速度、介質或溶劑之類型等)。

過程100可包括在高壓-高溫條件下燒結第二混合物(步驟108)。可將含有第二混合物之密封耐火模具放置在高壓高溫(high-pressure-high-temperature;HPHT)單元中,並且施加HPHT燒結條件以形成本文所揭示之cBN基複合材料(例如,經燒結粉壓坯)。步驟108可包括在約5吉帕斯卡(GPa)-8GPa之壓力及約1300-1600℃之溫度下燒結第二混合物。步驟108可包括在至少4GPa之壓力及至少1100℃之溫度下燒結第二混合物。cBN基複合材料(例如,經燒結粉壓坯)可具有奈米或亞微米範圍內之cBN晶粒尺寸,例如約0.1-10μm,約0.1-8μm,約0.1-6μm,約0.1-4μm,約0.1-2μm,約2-4μm,約0.1-1μm,約0.8-1.2μm,或約1μm。
根據過程100所形成之cBN基複合材料(例如,經燒結粉壓坯)可用於切割或機械加工難切割材料。例如,可將根據過程100所形成之cBN基複合材料形成為切割工具,以用於切割及/或機械加工高強度超合金,包括鎳基超合金(例如,英高鎳718、英高鎳625)、鈷基超合金(例如,合金188、海恩斯25、合金L605)、鐵基超合金(例如,A286)、或與此等超合金具有同等、較差或較好機械性質之任何材料。
不希望受任何特定理論之束縛,據信本文所揭示之cBN基複合材料(例如,經燒結粉壓坯)之組成及相可有助於改良耐磨性、韌性、耐化學性、硬度、熱硬度或其組合,從而改良切割及機械加工能力。表3顯示使用由本文所揭示之cBN基複合材料(例如,經燒結粉壓坯)所製成之切割工具之例示性切割性能。
在所示之實例中,樣品1-5表示由基於表1及2所示之組成及圖1所述之過程100所形成之cBN基複合材料(例如,經燒結粉壓坯)所製成之切割工具。在英高鎳718上以350米/分鐘(m/min)之速度及0.15毫米/旋轉(mm/旋轉)之饋入速度,同時將冷卻液連續施加至切割界面來進行切割測試。對樣品1-5進行0.25mm之預定側面磨損之切割測試。表3之最右邊一欄顯示工具壽命結束時之切割距離(以公里(km)計)。
樣品1及樣品2均含有約60體積% cBN,含Al相或化合物(Al2O3及/或AlN),含Zr相或化合物(ZrCN及/或ZrB2)及含W相或化合物(WB、W2B、W2B5、CoW2B2及/或CoWB),並且兩者皆不含有含鈦(Ti)相或化合物。樣品1與樣品2之間之區別在於樣品2含有W2B5及CoxWyBz(CoW2B2、CoW3B3及/或CoWB),而樣品1不含W2B5及CoxWyBz(CoW2B2、CoW3B3及/或CoWB),並且樣品2之經燒結晶粒尺寸略小。樣品1之切割距離為0.8km,樣品2之切割距離為 1.0km。樣品3及樣品4均含有約50體積% cBN,含Al相或化合物(Al2O3),含Zr相或化合物(ZrCN及/或ZrB2),含W相或化合物(WB、WC、CoW2B2、CoW3B3及/或CoWB),及含Co相或化合物(CoW2B2、CoW3B3及/或CoWB),並且兩者皆不含有含鈦(Ti)相或化合物。樣品3與樣品4之間之區別在於樣品3含有ZrB2,而樣品4不含ZrB2,樣品4含有WC,而樣品3不含WC。樣品3之切割距離為1.3km,樣品4之切割距離為1.0km。儘管樣品5亦含有約50體積% cBN,樣品5與樣品1-4之區別在於樣品5含有含Ti相或化合物(碳氮化鈦(TiCN)及/或氮化鈦(TiN)),並且不含有含Zr相或化合物及CoxWyBz。樣本5之切割距離為0.7公里。
不希望受任何特定理論之束縛,據信Al2O3之存在,CoxWyBz之存在,硼化鎢之存在以及含Zr化合物之存在可有助於改良切割能力。亦據信,相較於具有相對較高的cBN含量(例如,約60體積%,約65體積%)之cBN基複合材料,具有相對較低的cBN含量(例如,約50體積%,約45-55體積%)之cBN基複合材料可具有更好的切割能力。亦據信,在一些具體實例中,包括Al2O3、CoxWyBz、硼化鎢及含Zr化合物,並且不包括或實質上不包括含Ti化合物(例如氮化鈦(TiN)、碳氮化鈦(TiCN)、碳化鈦(TiC)、碳氧氮化鈦(TiCON)、氧氮化鈦(TiNO)或其組合)之cBN基複合材料具有比包括含鈦(Ti)黏合劑但不包括硼化鎢及/或CoxWyBz之更好的切割能力。
不希望受任何特定理論之束縛,據信某些晶相之特定組合及/或排除可有助於本文所揭示之cBN基複合材料(例如,經燒結粉壓坯)之增強的切割能力。例如,CoxWyBz以結晶相之形式存在於cBN基複合材料(例如,經燒結粉壓坯)中,從而有助於改良切割能力。例如,CoxWyBz可以結晶CoWB、結晶CoW2B2及/或結晶CoW3B3中之一或多種形式存在。例如,含Zr化合物以ZrB2及/或ZrCN之形式存在於cBN基複合材料(例如,經燒結粉壓坯)中,從而有助於改良切割能力。例如,在cBN基複合材料(例如,經燒結粉壓坯)中存在硼化鎢 (諸如WB、W2B及W2B5),從而有助於改良切割能力。
