Abstract
本发明公开了一种涂覆硬质合金刀片，尤其用于带有或不带有未加工表面，例如铸造表皮、锻造表皮、热轧或冷轧表皮、或预加工表面的低、中合金钢和不锈钢在恶劣条件，例如振动、长悬臂和切屑再切削下的有韧性需求的湿、干加工，优选为铣削。所述刀片的特征在于具有W和Cr合金Co－粘结相的WC－Co硬质合金，和包括至少三个TiCxNyOz层和至少位于光滑α－Al2O3的前刀面上的顶层的涂层。
Description
技术领域
本发明涉及一种涂覆硬质合金切削刀片，其尤其用于具有未加工表面，例如铸造表皮、锻造表皮、热轧或冷轧表皮、或预加工表面的低和中合金钢、不锈钢在不稳定条件下的有韧性需求的湿和干加工，优选地铣削。
背景技术
当利用硬质合金刀具加工低和中合金钢和不锈钢时，切削刃发生根据不同机理的磨损，例如化学磨损，磨料磨损，粘附磨损，以及根据由沿切削刃形成的裂纹，即所谓的梳状裂纹所引起的刃切屑。在恶劣切削条件下，常发生基体和刃边破裂。
不同的工件材料和不同的切削条件需要不同的刀片性能。例如，当切削带有未加工表面区域的钢部件或者在其他不同条件下切削时，涂覆硬质合金刀片必须基于坚硬的硬质合金基底并且具有良好粘性的涂层。当加工低合金钢和不锈钢时，粘附磨损通常是主要的磨损类型。这里通常必须使用1-3μm的薄CVD或PVD涂层。
可以采取措施改进或优化针对于特定磨损类型的切削性能。然而，通常，这种措施将对其他磨损特性具有负面影响。
一些可能措施的影响给出如下：
1)通过减少粘结相含量能够减少梳状裂纹形成。然而，低粘合剂含量将降低刀片的韧性，该刀片远不是人们所希望的。
2)改进的磨料磨损可以通过增加涂层厚度而获得。然而，厚涂层增大了片状剥落的风险，并且还将降低抗粘附磨损能力。
3)以高切削速度和在导致高切削刃温度的其他条件下加工需要具有较多数量的立方碳化物(WC-TiC-TaC-NbC的固溶体)的硬质合金，但是这些碳化物将促进梳状裂纹形成。
4)改进的韧性可以通过提高钴粘合剂含量而获得。然而，高钴含量降低了抗塑性变形能力。
到目前为止，同时改进所有的刀具性能是极为困难的。商用硬质合金等级因此相对于上述磨损类型中的一个或几个和特定的切削应用领域进行了优化。
US6,062,776公开了一种涂覆切削刀片，特别用于在湿或干条件下对带有或不带有未加工表面区域的低和中合金钢进行铣削。该刀片的特征在于，具有低含量立方碳化物和高W-合金粘结相的WC-Co硬质合金，包括具有柱状晶粒的TiCxNyOz最内层和κ-Al2O3层以及TiN顶层的涂层。
US6,406,224公开了一种涂覆切削刀片，还特别用于高速铣削带有或不带有磨损面区域的合金钢。该涂覆刀片包括硬质合金主体，其具有7.1-7.9wt％Co，0.2-1.8wt％金属Ta、Nb和Ti的立方碳化物，和余量的WC组成。该刀片涂覆有具有柱状晶粒的TiCxNyOz最内层和κ-Al2O3层以及TiN顶层。
EP-A-736615公开了一种涂覆切削刀片，特别用于灰口铸铁的干铣削。该刀片的特征在于，具有直的WC-Co硬质合金基底和由具有柱状晶粒的TiCxNyOz层和细粒结构的α-Al2O3顶层组成的涂层。
US2006/0204757A公开了一种涂覆切削刀片，适合于通过车削、铣削、钻削或通过类似的切屑形成加工手段进行金属加工。该刀片尤其用于间断的韧性需要的切削操作。
US6,200,271公开了一种涂覆车削刀片，尤其用于不锈钢的车削。该刀片的特征在于，具有高W合金的Co粘结相的WC-Co基的硬质合金基底和包括具有柱状晶粒的TiCxNyOz最内层、TiN顶层和细粒的κ-Al2O3内层的涂层。
发明内容
发明人在对市售刀片进行大量实验和多次测试之后发现，通过组合多个特定特征，可以获得尤其适于铣削的改进的切削刀片。所述组合特征是：特定的硬质合金组成，特定WC晶粒尺寸，合金粘结相，由多个限定层组成的内涂层和光滑的α-Al2O3顶部前刀面层。
该刀片对带有或不带有未加工表面区域的低和中合金钢，尤其是在例如振动、长悬臂梁、切屑锻造(chip-hammering)或切屑再切削的不稳定条件下或者在湿和干两种条件下通常有韧性需要的操作中具有改进的切削性能。还令人惊讶的是，本发明的刀片还对不锈钢实现良好加工。根据本发明的刀具与现有技术中的刀片相比，相对于上述许多磨损类型具有改进的切削特性。特别地，梳状裂纹韧性特性得以提高。
附图说明

具体实施方式
根据本发明的切削刀片包括硬质合金主体和涂层，所述硬质合金主体具有W和Cr合金Co粘结相，良好平衡的化学组成和适当选定的WC晶粒尺寸，所述涂层包括柱状TiCxNyOz内层，随后是光滑α-Al2O3顶层。优选地，TiN层是位于刀片间隙面(clearance face)处的顶层。
根据本发明，提供了一种涂覆切削刀片，其包括具有12.0-15.0wt％Co，优选地12.5-14.5wt％Co，最优选13-14wt％Co，0.52-0.64wt％Cr，优选地0.54-0.62wt％Cr，最优选地0.55-0.61wt％Cr和余量WC的组成的硬质合金主体。该硬质合金主体还可以包括较少量的其他元素，不过是在相当于工艺杂质的水平上。根据IEC标准60404-7测量的极化矫顽力(polarization coercivity)HcJ间接地测量WC晶粒尺寸并且应当具有12.5-14.5kA/m，优选地12.7-14.0kA/m范围内的值。钴粘结相与赋予本发明刀片希望特性的特定数量的W和Cr形成合金。粘结相中的W和Cr影响钴的磁性并且因此可以与值CW相关，CW定义为：
CW＝磁性％Co/wt％Co
其中，磁性％Co是磁性材料的重量百分比，wt％是硬质合金中Co的重量百分比。
CW值可以在1和约0.6之间变化，取决于合金度。较低的CW值对应粘结相中较高的W和Cr含量，并且CW＝1实际上相当于粘结相中没有W和Cr。
根据本发明已经发现，如果硬质合金主体具有0.76-0.84，优选地0.78-0.82，最优选地0.79-0.81范围之内的CW比的话，可以获得改进的切削性能。该硬质合金还可以包括少量(＜1体积％)的η相(M6C)，而没有任何有害的影响。由于特定的CW值(＜1)，还遵循，不允许在根据本发明的硬质合金中具有游离石墨。
该硬质合金刀片至少部分地涂覆有4.1-6.9μm厚的涂层，包括至少三层TiCxNyOz。该三层形成内涂层，带有α-Al2O3层作为至少位于前刀面(rake face)上的外层。这些TiCxNyOz层具有1.9-3.6μm的总厚度并且包括：
紧邻所述硬质合金的第一TiCxNyOz层，0.1-1μm，具有x+y＝1，x＞＝0，优选地x＜0.2，z＝0的组成。

所述硬质合金刀片主体至少部分地涂覆有4.1-6.9μm厚的涂层，包括至少三层TiCxNyOz，该三层形成内涂层，带有喷砂处理过的α-Al2O3层作为至少位于前刀面上的外层。这些TiCxNyOz层具有1.9-3.6μm的总厚度，包括：

还结合以下实例来说明本发明，这些实例应该认为是示例性的。应该理解，本发明不限于这些实例的特定细节。
实例1(发明)
制造下列类型的硬质合金铣削刀片，R390-11T308M-PM，R390-170408M-PM，R245-12T3M-PM，R300-1648M-PH和R300-1240M-PH，其具有13.5wt％Co，0.58wt％Cr，和余量WC的组成，并且HcJ值为13kA/m，CW值为0.80，如以Foerster Instruments Inc.的FORSTER KOERZIMAT CS 1.096测量的那样。该刀片随后如下涂覆：
0.5μm的TiCxNyOz第一层，具有大约x＝0.05，y＝0.95，并且z＝0的组成，该层利用由TiCl4，H2和N2组成的反应混合物通过已知CVD方法制成，
1.7μm的柱状TiCxNyOz第二层，具有大约x＝0.55，y＝0.45并且z＝0的组成，该层通过已知MTCVD工艺，温度885-850℃，并且CH3CN作为碳/氮源制成，和
0.5μm的TiCxNyOz第三粘接层。该第三层的晶粒为针形，并且组成为大约x＝0.5，y＝0和z＝0.5
由2.5μm的α-Al2O3组成的第四层，最后，通过使用已知CVD工艺沉积大约0.3μm的TiN顶层。XRD测量确认所述Al2O3层为100％α相。
在涂覆周期之后，该刀片的顶侧(前刀面)利用Al2O3粗砂和水的浆液经受猛烈的湿喷砂处理。该喷砂处理去除前刀面上的顶部TiN层，露出光滑的α-Al2O3，其中大部分晶粒如图1和2所示被磨扁，图1和2以6000X显示了氧化铝层的SEM图像，图1为喷砂处理之前的顶视图，图2是喷砂处理之后的顶视图。
实例2(现有技术)
制造下列类型的硬质合金铣削刀片，R390-11T308M-PM，R390-170408M-PM，R245-12T3M-PM，R300-1648M-PH和R300-1240M-PH，其具有11.5wt％Co，1.25wt％TaC，0.30wt％NbC和余量WC的组成，并且HcJ值为10.4kA/m，CW值为0.94，如以FoersterInstruments Inc.的KOERZIMAT CS 1.096测量的那样。该刀片随后如下涂覆：
0.5μm的由等轴晶粒组成的TiCxNy第一层(具有相当于估计的x＝0.95，y＝0.05的高氮含量)，其后为
4μm厚的TiCN层，其具有柱状晶粒，通过使用MTCVD工艺在885-850℃的温度下以CH3CN作为碳/氮源获得。在后续步骤中，在同一涂覆周期中，如EP-A-523 021中所公开的，在970℃的温度下，利用0.4％浓度的H2S掺杂剂沉积1.0μm厚的Al2O3层。0.3μm的TiN薄层按照已知的CVD工艺沉积在顶部。XRD测量显示出，Al2O3层由100％的κ相组成。所述硬质合金主体具有平均尺寸为1.7μm的WC晶粒。用带有包含硬质SiC晶粒的刷毛(straw)的尼龙刷子刷该涂覆刀片。在光学显微镜下观察被刷过的刀片显示出，TiN顶层已经沿切削刃刷落，留下光滑的Al2O3表面。对横向剖开的被刷样品进行涂层厚度测量显示出，沿刃边的Al2O3层的层厚度已经减少大约50％。
