Description
技术领域
本发明涉及一种用于钢板或钢带的铝基涂层,其中,涂层包括采用热浸法涂覆的铝基覆层,其中,在该覆层上设置了含有氧化铝和/或氢氧化铝的顶层。本发明还涉及一种用于制造包括铝基涂层的钢板或钢带的方法,其中,铝基覆层作为涂层通过热浸法涂覆到钢板或钢带上。本发明还涉及一种由采用前述方法制得的、带有铝基涂层的钢板或钢带制造冲压硬化的构件的方法。此外,本发明涉及一种由带有铝基涂层的钢板或钢带形成的冲压硬化的构件,其采用前述方法制得。
背景技术
已知的是,热变形的钢板特别是在汽车制造中得到日益频繁的应用。通过也称为冲压硬化的过程,可以产生高强度的构件,这些构件主要应用在车身区域中。冲压硬化在原则上可以采用两种不同的方法变型来进行,即通过直接的或间接的方法来进行。按照间接的方法,变形和硬化的处理步骤彼此分开地进行,而按照直接的方法,这些处理步骤在一个模具中一起执行。但下面只考察直接的方法。
在直接的方法中,把钢板板材加热到所谓的奥氏体化温度(Ac3)以上,接下来把如此加热过的板材转移到成型模具中,并在单级的变形步骤中变形成最终的构件,在此同时,通过冷却的成型模具,以高于钢的临界冷却速度的速度予以冷却,从而产生硬化的构件。
用于这种应用领域的已知的可热变形的钢例如是锰-硼-钢“22MnB5”,以及最近根据欧洲专利EP 2 449 138 B1的可空气硬化的钢。
除了未涂层的钢板外,在汽车工业中还使用带有用于冲压硬化起皮防护的钢板。除了提高最终构件的耐腐蚀性外,这里的优点还在于,板材或构件在炉子中不起皮,由此减少了因剥落的氧化皮而导致的压制模具受损,并且通常不必在后续处理之前繁琐地对构件进行喷砂。
对于冲压硬化,目前已知通过热浸涂覆施加的如下(合金)涂层:铝-硅(AS)、锌-铝(Z)、锌-铝-铁(ZF/镀锌)、锌-镁-铝-铁(ZM)以及由锌-镍或者锌形成的电解沉积的涂层,其中,后者在热变形之前转变为铁-锌合金层。这些防腐涂层通常采用连续的馈通方法涂覆到热带或冷带上。
德国公开文献DE 197 26 363 A1描述了一种电镀的金属带,其包括由含碳的钢构成的基体,该基体在一侧或两侧设有由非铁金属构成的覆盖材料。建议采用铝或铝合金作为覆盖材料。也对覆盖材料进行氮化或进行阳极氧化处理,以便提高覆盖材料表面的耐磨损性和耐腐蚀性。
由专利文献DE 10 2014 109 943 B3已知制造带有由铝合金构成的金属防腐保护涂层的钢产品。在表面激活后,即在去除表面的惰性氧化层之后,冷轧的或热轧的钢产品通过浸入到熔融的镀槽中进行涂层。该熔融的镀槽除了Al和不可避免的杂质之外,还含有Mn和/或Mg、Fe、Ti和/或Zr。这相比于AlSi-合金会提高耐腐蚀性。该防腐涂层可以附加地予以阳极氧化。
由德国专利DE 601 19 826 T2已知,借助对由可冲压硬化的钢构成的初级产品的淬火,通过在变形模具中的热变形来制造构件。在这里,金属板材通过热变形在一间或冷却的模具中变形而形成一构件,该金属板材先前被加热到奥氏体化温度之上直至800-1200℃,且必要时设有由锌构成的或者基于锌的金属覆层;其中,在变形期间通过快速的散热,金属板或构件在变形模具中经历了淬火硬化(冲压硬化),通过所产生的马氏体的淬火组织(硬化结构)达到了所要求的硬度特性。
由德国专利DE 699 33 751 T2已知,借助对由可冲压硬化的钢构成的、带有铝合金涂层的初级产品的淬火,通过在变形模具中的热变形来制造构件。在此,在变形之前将带有铝合金涂层的金属板加热到700℃以上,其中,在表面上形成基于铁、铝和硅的金属间化合物,随后使金属板变形,并以高于临界冷却速度的速度予以冷却。
铝基覆层的优点在于,除了(例如在加热参数方面的)较大的加工窗口外,完成的构件在后续处理之前不必进行喷砂。此外,铝基覆层没有液态金属脆化的风险,并且,不会在靠近表面的基底区域中在以前的奥氏体晶界处形成微裂纹,所述微裂纹在深度超过10μm时会对疲劳强度有不利影响。
然而,在使用铝基覆层时的困难是,在热变形之前于辊底式炉中加热钢板材时,覆层会与陶瓷的输送辊发生反应,这明显缩短了炉辊的寿命。此外,在冲压硬化时,由于在加热过程中与铁结成合金的铝-硅覆层,模具的磨损很高。另外,在加热过程中,表面结构或覆层厚度的不均匀导致焊接问题,特别是在汽车工业中经常使用的电阻点焊时,其因构件表面上的局部变化的电阻而导致焊接问题。
但是,即使在铝基覆层的冷变形情形中也会出现问题。例如,在模具中变形期间的磨损相比于标准的锌覆层明显较高,这增大了模具磨损和维护代价,会因压入碎末而导致后续部件故障。
发明内容
因此,本发明的目的是,提出一种用于钢板或钢带的铝基覆层,其特别适用于热变形和冷变形。此外,要提出一种用来制造这种涂层的方法,以及一种由这种钢板或钢带制造冲压硬化的构件的方法,和一种由这种钢板或钢带形成的冲压硬化的构件。
本发明的教导包括一种用于钢板或钢带的铝基涂层,其中,该涂层包括采用热浸法涂覆的覆层,该覆层的特征在于,在该覆层上设置了含有氧化铝和/或氢氧化铝的顶层,该顶层是通过等离子氧化和/或通过在至少90℃、有利地至少95℃的温度下的热水处理形成的,和/或是通过在至少90℃、有利地至少95℃的温度下的水蒸汽处理形成的。在此,覆层可以有利地在熔池中形成,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。
铝基覆层是指如下的金属覆层:就其而言,铝在质量百分比中是主要组成部分。可能的铝基覆层的例子是:铝、铝-硅(AS)、铝-锌-硅(AZ)以及混合有附加元素比如镁、锰、钛和稀土的同类覆层。
此外,本发明的教导包括一种用于钢板或钢带的铝基涂层,其中,该涂层包括采用热浸法涂覆的铝基覆层,其中,在该覆层上设置了含有氧化铝和/或氢氧化铝的顶层,该顶层是通过阳极氧化产生的,其特征在于,覆层是在熔池中形成的,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。
然而,通过在铝基涂层上形成限定的含有氧化铝和/或氢氧化铝的顶层,铝基涂层的前述不利的方面可以明显得到减小,或者甚至完全得到防止。
具体实施方式
在此,含有氧化铝和/或氢氧化铝的顶层在热变形时用作在覆层与陶瓷炉辊之间的分隔层。由此有效地避免金属材料传递到炉辊上。此外,含有氧化铝和/或氢氧化铝的顶层把钢带的铝基覆层——其与铁结合成合金——与变形模具的金属模具表面分隔开,因而用作分隔性的变形辅助件。这减小了磨损和磨蚀,进而减小了模具磨损和维护,因为相比于现有技术,由于冲压硬化,这些层明显很少变化,进而明显很少磨蚀。这在图1a)-d)中示出。这些图示出了AS-覆层表面的扫描电子显微图像的对比:a)在无冲压硬化时的未处理的初始状态;b)无冲压硬化时的阳极氧化状态;c)冲压硬化之后的未处理状态;d)在冲压硬化之后的阳极氧化状态。
在产生顶层之前进行碱性预处理,有可能随后例如用硫酸或硝酸进行酸洗,然后冲洗设有铝基涂层的钢板或钢带,这在此有利地去除了已经通过大气氧化产生的、随机地形成的层,由此为以后产生的顶层提供了一确定的初始状态。
然而,在大批量生产上,在带有铝基覆层的钢带上产生确定的含有氧化铝和/或氢氧化铝的顶层是一个挑战。
根据本发明,含有氧化铝和/或氢氧化铝的顶层因此按照本发明通过等离子氧化而产生。附加地或替代地,在至少90℃、有利地至少95℃的温度下进行热水处理,或者,在至少90℃、有利地至少95℃的温度下的水蒸汽中进行处理。对覆层或顶层的这种处理也叫密封。此外,含有氧化铝和/或氢氧化铝的顶层采用阳极氧化的方法产生。在此,覆层是在熔池中产生的,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。阳极氧化的方法相比于化学的氧化方法明显应用广泛。特别有利的是,该方法在对涂层钢带的连续处理中进行。
对铝(合金)层的阳极氧化既可以采用直流方法进行,又可以采用交流方法进行。
如果例如在硫酸-电解液中阳极氧化地处理铝或铝层,则在所形成的电场中,硫酸的被充负电的硫-负离子和水的OH-离子移动至阳极。在阳极上,它们与Al3+离子发生反应,形成氧化铝。按照法拉第定律,层厚与流过的电荷量有关。由此可以实现按规定调节氧化层的厚度,以便其恰当地符合相应的使用目的。
对于铝的阳极氧化来说,在本文献中,在流过的电流为1Ah/dm2时,形成大约20μm的层厚。
在试验中已表明层足够厚是有利的,以便保证在炉辊与覆层之间的分隔。例如,最小0.05μm、最大4.0μm的平均层厚已表明是有利的,该层厚同时还可以实现良好的焊接性,特别是点焊性。
已表明平均处于0.1和1.0μm之间的层是特别有利的,因为在此已发现对减小模具磨损有明显的正面效果,而且在焊接特性方面绝无限制。
对于铝和铝合金的阳极氧化,可以考虑各种不同的电解液系统(例如基于硼酸、柠檬酸、硫酸、草酸、铬酸、烷基磺酸、碳酸、碱金属碳酸盐、磷酸、氢氟酸)。
视电解液系统而定,用于所述工艺的典型的电流密度处于1-50A/dm2之间。由于在所述工艺中以恒定的电流工作,所以产生了电压。该电压通常处于10-120V的范围内。视电解液系统而定,电解液温度在0-65℃之间。通过选择电解液温度,可以例如影响层的硬度。在基于硫酸或草酸的电解液中,在低的电解液温度(例如0-10℃)情况下得到特别硬的层。
在阳极氧化期间,由紧密地排列并具有六角形横截面的氧化晶胞形成一覆盖整个表面的纳米微孔的氧化物层。这些微孔朝向电解液侧开口。微孔直径与所用的电解液的种类有关。视位于其下面的覆层的局部的化学组分而定,氧化层能够以不同的相局部地形成(见图1b)。在试验中,按照硫酸-直流-方法已表明,在阳极氧化处理期间,在AS-合金覆层中包含的各相在显微层面的氧化物层厚度和微孔大小方面表现不同。由此形成了不同于最初金属表面的微观结构。在宏观层面上,层的形成进行得非常均匀。
图2示范性地示出阳极氧化的AS-覆层的纳米微孔表面结构的扫描电子显微照片。在所形成的纳米微孔的层中,浸入颜料(有机的或无机的)或者功能色素(例如导电的金属颗粒、富勒烯、纳米结构颗粒),利用它们可以调节层的着色和特性,比如导电性、硬度、耐腐蚀性、抗菌特性。
有利地随后的密封步骤(也叫密封)通过吸收结晶水来封闭微孔结构,并且例如防止进一步吸收颜料或功能色素。这种密封可以通过水蒸汽处理或者热水处理来实现。为此,至少90℃、特别有利地至少95℃的温度已表明是有利的。密封时间与氧化层厚度有关。在此,在氧化层厚度增加时,密封时间也延长。有利地,在密封期间,添加物比如金属盐可以改善耐腐蚀性和颜色稳定性。
通常,铁的存在会干扰铝和铝合金的阳极氧化。因此必须确保来自钢衬底的铁不与电解液接触。因此对于涂层的板材,必须繁琐地保护切削边(例如通过凸缘、边缘掩饰、涂层、涂饰、膜)。在(未修边的)涂层的钢带阳极氧化时,在带边缘没有暴露的钢,因为这些带边缘在热浸过程中就已一同被涂层。这显著地简化了阳极氧化的过程,同时保证了其稳定性。
此外可考虑的是,对铝基层只进行单侧的根据本发明的表面处理,以便例如仅在炉辊的耐受性方面实现积极的效果。也可以考虑在两侧进行不同的根据本发明的表面处理。
试验表明,对于为了密封而经历过水蒸汽处理的样本,即使没有先前的阳极氧化或等离子氧化,也实现了根据本发明可以使用的薄的氧化层。
有利地,铝基覆层特别适用于热变形或冷变形。
本发明的方法包括,制造具有铝基涂层的钢板或钢带,其中,采用热浸法将铝基覆层被作为涂层涂覆到钢板或钢带上,其特征在于,带有覆层的被涂层的钢板或钢带在热浸过程之后且在热变形或冷变形的变形过程之前,经历等离子氧化和/或热水处理和/或在水蒸汽中的处理,其中,在形成氧化物或氢氧化物的情况下,在覆层的表面上形成含有氧化铝和/或氢氧化铝的顶层。在此,覆层可以有利地在熔池中产生,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。
有利地,在至少90℃、有利地至少95℃的温度下进行可选的热水处理或水蒸汽处理。
另一个根据本发明的方法包括制造具有铝基涂层的钢板或钢带,其中,作为涂层,采用热浸法将铝基覆层涂覆到钢板或钢带上,其中,带有覆层的钢板或钢带在热浸过程之后且在变形过程之前经历阳极氧化,其中,在形成氧化物或氢氧化物的情况下,在覆层的表面上形成含有氧化铝和/或氢氧化铝的顶层,其特征在于,覆层在熔池中产生,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。
在本发明的一种有利的设计中,顶层在连续的过程中涂覆到覆层的表面上。
本发明的阳极氧化有利地在基于硼酸、柠檬酸、硫酸、草酸、铬酸、烷基磺酸、碳酸、碱金属碳酸盐、碱金属磷酸盐、磷酸或氢氟酸的介质中进行。
介于1-50A/dm2之间的电流密度、10-120V的电压、0-65℃之间的电解液温度已表明是用于阳极氧化的有利的方法参数。
在本发明的一种有利的改进中规定,在涂层的阳极氧化和/或等离子氧化的步骤之后,且在通过热水处理和/或水蒸汽处理进行覆层密封之前,把把影响顶层功能的色素和/或颜料色素引入到顶层中。由此可以随意地设计被涂层的钢板或钢带的表面的颜色,或者可以针对所提出的要求如上所述地有针对性地调节涂层的功能特性。
在本发明的另一有利的改进中,通过本发明的方法制得的铝基覆层特别适于热变形或冷变形。
为了冲压硬化由根据本发明设有铝基涂层的钢板或钢带形成的构件,提出一种方法,其特征在于,钢板或钢带为了淬火目的而至少局部地加热到Ac3以上的温度,随后在该温度情况下变形,然后以至少局部地高于临界冷却速度的速度冷却,其中,铝基涂层是采用热浸法涂覆的覆层,其中,涂层在热浸过程之后且在加热到变形温度之前经历了阳极氧化、和/或等离子氧化、和/或热水处理、和/或水蒸汽处理条件下的处理,其中,表面上的涂层被氧化,并形成氧化物或氢氧化物,覆层在熔池中产生,该熔池含有8-12%(重量)的Si、1-4%(重量)的Fe,其余为铝。
此外,本发明包括一种冲压硬化的构件,其按照前述方法由根据本发明的设有铝基涂层的钢板或钢带制得。
在研究期间,还发现了一些其它的也涉及冷变形构件或冷变形过程本身的、有利的特性:
a)本发明的含有氧化铝和/或氢氧化铝的顶层把钢带的金属的铝基覆层与变形模具的金属模具表面分隔开,因而用作分隔性的变形辅助件。这通过降低摩擦阻力和避免所谓的粘滑效应,减少了焊接点,拓宽了变形区。该问题特别是在变形速度缓慢并且材料强度很大时出现,且可以显著地限制工艺窗口。通过本发明的层,工艺窗口显著地朝向速度较小并且变形力较大的方向开启,进而变形进程明显更加稳健。此外,对于变形进程有利的是,由于含有氧化铝和/或氢氧化铝的顶层的侧向不均匀的构造,在工件与模具之间没有平面接触,而是接触减少。
b)同时,本发明的含有氧化铝和/或氢氧化铝的顶层的微孔表面可以增大表面的吸油能力,并且明显减小油移效应。钢卷,即卷成卷的钢带,已在制造商那里被上油,以便一方面在客户加工之前保证防腐蚀,另一方面,为后续的变形过程提供预先涂油。在暂存期较长并且温度升高时,油会从钢卷绕圈中漏出。于是在金属板表面上就没有油了,这导致必须繁琐地再次涂油。采用根据本发明构造的顶层就可以防止这一点。
c)本发明的含有氧化铝和/或氢氧化铝的顶层的相比于金属覆层的较大的、高达350HV 0.025的硬度,使得可把该系统用于其它应用,在这些应用中,重要的是平滑的、减小滚动阻力的表面,比如支撑面/轴承面、衬套或者例如抽屉的牵拉机构。对于金属的覆层来说,这里也有冷焊接的危险,进而有在轴承表面上形成能严重影响滑动轴承或滚动轴承的功能的材料的危险。
d)本发明的含有氧化铝和/或氢氧化铝的顶层在腐蚀性负载情况下产生阻抑效果,这种阻抑效果保护金属的耐腐蚀覆层本身。在表面受损时,金属覆层通过a)遮盖和b)阴极腐蚀防护来保护好的钢板。结合以另一阻抑层(例如漆),这就是所谓的双层系统。漆虽然对于水具有高的蒸汽阻抑性,但耐磨强度通常不是很强。本发明的含有氧化铝和/或氢氧化铝的顶层通过阻抑效果与高的耐磨强度的组合来解决该问题。此外,相比于全部已知的漆,本发明的层明显更加耐热,因而能实现即使温度较高也可以在腐蚀性环境中使用。
e)此外,高温情况下的氧化物生长急剧地减少,因为由于层的紧凑的原子构造,氧化层生长所必需的离子交换被表面所阻挡。同样地,有效地抑制了覆层的蒸发。
f)相比于纯金属表面的另一优势在于,对酸性的、特别是碱性的介质的耐受性提高了。在此,本发明的含有氧化铝和/或氢氧化铝的顶层就像分隔层那样起作用,该分隔层保护免于受这些介质的腐蚀性效果的影响。
g)同时,本发明的顶层即使没有先前的磷化处理也能很好地上漆,因为该顶层由于其无机的性质能实现理想的化学交联,且由于大的表面(在省去密封步骤情况下)能实现很好的物理交联。
h)本发明的含有氧化铝和/或氢氧化铝的顶层有效地提高了表面的电阻,从而视层厚(也超过20μm)而定,即使没有保护漆也能实现高达2kV的击穿电压。
i)由于含有氧化铝和/或氢氧化铝的顶层的微孔性,在密封过程之前,存在渗入色素的可行性。在铝构件的装饰性的阳极氧化涂层领域中,被彩色地着色的铝表面是已知的,并且非常广泛。但除了色彩信息外,借助这种色素也可以调整其它技术特性,比如导电能力或者抗菌效果。
