Description
技术领域
本发明涉及一种涂层切削刀具,该涂层切削刀具在两个非金属功能层或者层系统之间包括一个或者多个金属中间层。根据本发明的切削刀具由于韧度增加将展示出优良的寿命,因此显示出承受负载变化的更好能力。另外,本发明便于沉积较厚的PVD的涂层而没有沿着刃线剥落的风险,因此能够沉积具有更好的抗后刀面磨损性的较厚的涂层。涂层的更高韧度性质有助于甚至在锐利或者研磨刀刃上的适度厚的涂层。
背景技术
通常,如果将涂层沉积到切削刀具的表面上,则所述切削刀具的寿命显著地增加。今天的大多数切削刀具均涂覆有PVD或者CVD涂层如Ti(C,N)、TiN、(Ti,Al)N、(Ti,Si)N、(Al,Cr)N或者Al2O3。与CVD涂层相比,PVD涂层具有几种吸引人的性质,例如在沉积状态中更加精细的颗粒涂层和压缩应力,这给出更好的容忍负载变化的能力。然而,PVD涂层通常必须非常薄,这是因为自然地、通常围绕刃线、或者在加工期间,较厚的PVD涂层会引起剥落、碎裂、所谓的刃线剥落和崩刃。
在剥落发生之前能够在刀具上沉积的最大涂层厚度依赖于刀刃半径ER。具有小ER的锐利刀刃以及研磨刀刃特别地易于沿着刃线发生剥落和崩刃,并且因此通常沉积薄的涂层。然而,如果刃线能够保持完好,则稍微较厚的涂层将是优选的,这是因为较厚的涂层在大多数情形将由于更好的耐磨性而产生延长的刀具寿命。
利用PVD技术沉积金属层是在PVD工艺中已被确定的技术。为人熟知的是,在沉积其余涂层之前将金属层直接地沉积到基体表面上能够加强涂层的粘附力。
并且曾经很少作出对在非金属层之间沉积金属层的尝试。
US2002/0102400A描述了一种包括交替的金属层和陶瓷层的耐磨涂层。该涂层将具有带有低的微观韧性的精细颗粒表面。该涂层优选地被沉积到钢、钛或者碳化物(例如TiC)的基体上,但是优选地被沉积到钢的基体上。基体优选地为牙科刀具、外科刀具或者切削刀具的形式。在该实例中,钢制刮牙器具有所述涂层。
本发明的一个目的在于提供一种涂层切削刀具,该涂层切削刀具具有即使在锐利几何形状和研磨刀刃上也不易于剥落、碎裂、所谓的刃线剥落和崩刃的PVD涂层,因此获得具有增加的刀具寿命的刀具。
本发明的一个目的在于提供一种涂层切削刀具,该涂层切削刀具具有锐利的未涂覆刀刃半径ER和厚的PVD涂层,而不存在刃线剥落、碎裂、崩刃等风险,因此获得具有增加的刀具寿命的刀具。
本发明的另一个目的在于提供一种涂层切削刀具,该涂层切削刀具带有改进的抗后刀面磨损性。
本发明的另一个目的在于提供一种制造具有以上所披露的益处的涂层切削刀具的方法。
已经令人惊讶地发现,通过提供一种包括置于两个非金属功能层或者层系统之间的金属中间层的涂层切削刀具,能够实现以上目的。
附图说明
图1示出刀片的刀刃的抛光横截面。分别绘出平行于和垂直于支撑面的两条线。从这两条线上找到两个参考点,我们从此进一步找到中心。ER现在被定义为在从中心到刀刃的五个不同角度的平均距离。
