Description

耐磨性能增强的氧化物涂层刀具
本发明涉及一种用于成屑加工的氧化物涂层切削刀具。
在切削刀具上化学气相沉积氧化铝是一项成熟的技术。Al2O3以及其它耐高温材料的耐磨损性能已在文献中大量讨论过。
CVD技术也被用来制造其他金属的氧化物、碳化物和氮化物涂层,该金属选自元素周期表中IVB、VB和VIB族中的过渡金属。许多这类化合物被用作耐磨和保护涂层,但很少受到象TiC、TiN和Al2O3那样的广泛关注。
Al2O3以几种不同的相结晶,α,κ,γ,β,θ等,在CVD制取的耐磨Al2O3涂层中最常见的两种相是热力学稳定的六方α相和亚稳定的κ相。一般地,κ相是粒径在0.5~3.5μm范围内的细晶结构,常表现出柱状涂层形态,而且κ-Al2O3涂层没有结晶缺陷,且没有微孔或空洞。κ-Al2O3的结晶结构基本上为斜方的,晶胞可用正交指数表示,它可转换成具有六方指数的六方晶胞。
在混合的α+κ-Al2O3涂层中,α-Al2O3晶粒常较粗大,取决于沉积条件,其粒径为1~6μm。这种情况下经常出现气孔和结晶缺陷。
在商业化切削刀具上,常常在TiCxNyOz涂层碳化物或陶瓷基体上涂覆Al2O3(见,例如美国专利号No.3837896,现在的美国再公告专利号No.29420和美国专利号No.5071696),TiCxNyOz与Al2O3涂层间的界面化学反应尤其重要。
用氧化物涂覆硬质合金刀具从而进一步提高它们的耐磨性在本质上是公所周知的。在例如美国再公告专利号No.29420和美国专利号Nos.4399168,4018631,4490191和4463033中就有证据。这些专利揭示了氧化物涂层体以及例如TiC涂层硬质合金的不同预处理如何增强了下一步沉积的氧化物层的粘附性能。氧化铝涂层体在美国专利号No.3736107,5071696和5137774中有进一步揭示,其中Al2O3层依次为α相,κ相,α+κ混合相。
Smith在US4619866描述了一种在掺杂剂例如硫化氢(H2S)的影响下,通过利用一种金属卤化物的水解反应而制备快速生长Al2O3层的方法。所得的涂层包括κ相小晶粒和α相大晶粒的混合相。该工艺制备的涂层具有在被涂覆基体周围均匀的层厚分布。
美国专利号No.5071696揭示了通过在一种MX层上外延沉积而涂覆有单相κ-Al2O3层的刀体,其中MX是取自周期表的IVB、VB或VIB族的一种金属的碳化物、碳氮化物或氧碳氮化物。瑞典专利申请9101953-9揭示了一种生长细晶κ-Al2O3涂层的方法。
瑞典专利申请No.9203852-0揭示的单相α-Al2O3层在(012)方向具有择优晶体生长取向。瑞典专利申请No.9304283-6的是在(110)方向上,瑞典专利申请No.9400089-0的是在(104)方向上。
因而本发明的目的是利用适宜的成核和生长条件在硬质合金基体上或优选地在上述TiCxNyOz涂层上提供至少一种具有所需显微结构和结晶学结构的基本单相的多晶κ-Al2O3层,以便把Al2O3层的所说的性质稳定化。
本发明的另一个目的是提供一种加工球轴承钢时切削性能增强的氧化铝涂层切削刀片。
图1是用要求保护的工艺制备的典型Al2O3涂层在2000放大倍数下的扫描电镜(SEM)俯视图。
根据本发明,提供了一种在其上沉积有耐磨涂层的硬质合金体的刀具。涂层含有一层或多层耐高温层,其中至少一层是κ相多晶体的致密Al2O3织构层。
根据本发明涂覆的切削刀具,在使用切削液加工球轴承钢时比现有技术的刀具表现出增强的耐磨性。
更确切地,涂层刀具含有一个烧结硬质合金体、金属陶瓷或陶瓷体的基体,优选地在一种金属粘结相中有至少一种金属碳化物。涂层结构中的各个层可以是TiC或选自由元素周期表中的IVB、VB、VIB族的金属,B、Al和Si组成的组中的一种金属的相关碳化物,氮化物,碳氮化物,氧化物和氧碳氮化物和/或其混合物。所说的涂层的至少一层是与基体相接触。然而,涂层结构中的至少一层是无微孔和结晶缺陷的细晶、致密、基本单相的κ-Al2O3层。这层涂层是具有厚度d=0.5~25μm,优选地1~10μm以及粒径0.5~6μm;优选地0.5~4μm的择优织构层。
根据本发明,该Al2O3层经X射线衍射法(XRD)测定在(210)方向具有择优晶体生长取向。织构系数TC可定义为: TC ( hk 1 ) = I ( hk 1 ) I 0 ( hk 1 ) { 1 n Σ I ( hk 1 ) I 0 ( hk 1 ) } - 1
式中,
I(hk1)=(hk1)反射的测试强度,
I0(hk1)=ASTM标准粉末图样衍射数据的标准强度。
n=计算中所用的反射面的数目,所用的(hk1)反射面有(002),(112),(013),(122),(113),(032),(210),(222),(050)。
根据本发明,(210)晶面的TC值大于1.5,优选地大于2.5,最优选地大于3.0。
在一个优选实施例中,根据本发明的氧化铝涂层优选地是最外层,但也可在其上沉积一层或更多层涂层例如一层薄的厚度为<1μm的TiN层。
在一个更优选的实施例中,所说的氧化铝层与优选地为涂层最内层的TiCxNyOz层相接触。
根据本发明,Al2O3织构层是通过仔细控制Al2O3成核过程中的工艺条件而得到的,此外在Al2O3成核前,把生产气体的氧化势例如水蒸汽的浓度控制在5ppm以下是至关重要的。Al2O3的成核是通过按下述控制反应气体的顺序开始的:H2和HCl以上述顺序先流进反应器,然后是AlCl3,CO2最后流入。成核过程中所加的HCl量应控制在2.5与10vol%之间,优选地在3.0与6.0vol%之间,最优选地在3.5与5.0vol%之间。成核过程中温度优选地在950℃与1000℃之间,氧化铝沉积过程中的生长步骤可在与成核步骤相同的温度下进行,但要添加掺杂剂,一种含硫气体,优选地为H2S,以提高沉积速率。然而,确切的条件在一定程度上取决于所用设备的结构。决定是否已达到所必需的织构和涂层形态并在必要时根据现场情况改变成核和沉积条件以便产生织构度和涂层形态,是熟练技工权限范围的事。
已发现一个平滑的涂层表面会进一步提高刀片的切削效果。可通过用细晶粒(400-150目)氧化铝粉对涂层表面进行轻微的湿法喷砂处理或用基于例如瑞典专利申请9402543-4所揭示的那种SiC的刷子对刀刃进行涂刷处理来获得平滑的涂层表面。
