Abstract

本发明涉及一种以确定性的表面结构(2)精整的钢板(1、1’)及其制造方法。

Description

具有确定性的表面结构的钢板
技术领域
本发明涉及一种以确定性的表面结构精整的钢板。此外，本发明涉及一种用于制造以确定性的表面结构精整的钢板的方法。
背景技术
由现有技术已知这种类型的以确定性的表面结构精整的钢板，参见例如专利文献EP 2 892 663 B1。
关于已知的现有技术，存在优化需求，特别是考虑到减少对过程介质的需求和/或符合需求地提供过程介质。
发明内容
因此，目的是提供一种以确定性的表面结构精整的钢板，该钢板与现有技术相比提供了相同的或更好的特性。
该目的通过权利要求1的特征来实现。
在经精整的钢板上提供限定性的表面结构对于尤其在用于制造汽车构件的继续加工工业中的其它工艺是重要的。在构件制造过程中，特别是在成形工艺中，有利的是，所使用的过程介质，例如油和/或润滑剂是均匀的并且以必要的覆层存在于与成形工艺相关的位置处。与成形工艺相关的这些位置通常是钢板和成型工具的接触面，因此不是在钢板中的冲压部(过程介质优选积聚在所述冲压部中)，而是所述表面是钢板上的隆起面的形式。发明人发现，在表面结构从钢板的表面出发冲压到钢板中时，在以确定性的表面结构精整的钢板中可以提供与现有技术相比相同的或更好的特性，其中，表面结构具有从表面出发延伸至谷区域的侧面区域，其中，根据本发明，至少侧面区域具有大于20nm的粗糙度Ra，以使对过程介质的需求最小化和/或将过程介质更靠近或邻近与成形工艺相关的位置地存储。通过限定地设置粗糙度Ra(算术平均粗糙值)，其中在DIN ISO EN 4287中给出了用于确定Ra值的方法，至少在表面结构的侧面区域中具有大于20nm，尤其大于50nm，优选大于100nm，优选大于150nm，进一步优选大于200nm的粗糙度Ra，能够尤其有针对性地对局部的过程介质分布产生影响，其中尤其通过确定性的表面结构的根据本发明的成型
Figure BDA0003551270650000021
导致具有为了钢板表面更好的工艺相关特性的刻意造型的侧面区域的钢板，使得过程介质目标明确地引入靠近成形工艺相关的位置。通过有针对性地设置的粗糙度Ra，可以提供相应的反应面或者说边界层。在侧面区域中的粗糙度Ra按需要可以限制到最大800nm，尤其最大700nm，优选最大600nm，优选最大500nm，特别优选最大400nm，因为钢板的表面尤其在随后的成型步骤中，例如在深冲、拉伸或弯曲时，尤其在钢板的外部纤维上经受大的形状变化。在此位置处尤其与确定性的表面结构的例如强烈突出的纹理相互作用，由于缺口效应而导致应力集中并且因此如果存在覆盖层，则会导致覆盖层失效。
确定性的表面结构可以理解为反复出现的表面结构，其具有限定的形状和/或构造，参见EP 2 892 663 B1。此外，尤其属于此的是具有(类似)随机外观的表面，然而所述表面借助确定性的纹理化方法产生并且因此由确定性的形状元素组成。
钢板一般理解为扁钢产品，该扁钢产品可以以板材形式或者以板坯形式或者以带材形式提供。
其他有利的设计方案和改进方案从下面的描述中得出。来自权利要求、说明书以及附图的一个或多个特征可以与一个或多个其它特征结合以形成本发明的其它设计方案。独立权利要求的一个或多个特征也可以与一个或多个其他特征结合。
根据本发明钢板的一种设计方案，表面结构具有侧面区域，该侧面区域从表面出发延伸至谷区域并且相对钢板的垂线以1°至89°之间的角度构造。该角度尤其可以在50°到87°之间，优选在60°到85°之间，特别优选在65°到82°之间构造。表面结构的谷区域和侧面区域(负形状)基本上相应于在精整辊上的表面(正形状)，精整辊通过相应地作用于钢板而构造或冲压出表面结构。环绕和构造表面结构的侧面区域与在侧面区域处一体连接的谷区域一起限定借助于精整冲压到钢板中的表面结构的封闭的体积。该封闭的体积、所谓的空体积可以为了随后借助成形方法的加工而与待施加的过程介质、尤其油相匹配。
在经精整的钢板上的确定性的表面结构(负形状)的几何设计方案(大小和深度)尤其取决于如何在精整辊上设计相应的几何结构(正形状)。优选使用激光纹理化方法，以使得能够通过材料去除来设置精整辊表面上的有针对性的结构(正形状)。特别是可以通过有针对性地控制能量、脉冲持续时间和选择作用到精整辊表面上的激光射束的合适的波长，对结构的设计产生积极的影响。随着高的或更高的脉冲持续时间，激光射束与精整辊表面的相互作用时间提高并且可以去除精整辊表面上的更多材料。脉冲在精整辊表面上留下基本上圆形的坑，该一个坑或多坑情况下的多个坑在精整过程之后形成钢板上的隆起部的表面或面以及因此形成钢板和成型工具之间的接触面。脉冲持续时间的降低对坑的形成有影响，特别是坑的直径可能减小。通过脉冲持续时间的降低，尤其在使用短脉冲或超短脉冲激光器时，可如此针对性地在精整辊的表面上设置几何结构(正形状)，以由此使钢板表面如此纹理化，使得在经精整的钢板的表面结构的侧面区域中可以产生限定的粗糙度Ra。这例如通过以下实现，使精整辊表面纹理化的激光脉冲持续时间减小，并由此可以以较高的分辨率在辊上产生几何结构。尤其是通过由激光和精整辊的较短相互作用产生的高分辨率或小的坑面，可以在侧面区域上有针对性地设置侧面区域的较粗糙的面和任意的坡度(角度)。
在侧面区域中的粗糙度的有针对性的设置和可选地侧面区域的角度的限定的设置不仅可用于成形工艺。特别是与在侧面区域中的粗糙度的设置相结合地有针对性地改变角度，实现在钢板表面的功能化时的更多的自由度。
因此，通过有针对性地设置侧面区域中的粗糙度Ra，可以提供例如用于化学(后)处理、尤其是在经精整的钢板和过程介质之间以清洁和/或磷化的形式的化学(后)处理的限定的和/或大的反应面。优选地，在清洁时有针对性地设置的侧面区域的粗糙度Ra，提供了表面特性，从而例如能够相对简单地至少部分地和/或局部地、尤其在没有对侧面区域中的表面结构的粗糙度产生负面影响的情况下去除边界层、尤其氧化物覆盖层上的干扰的覆层。
例如，根据本发明的钢板的粘性能力基本上也可以通过在侧面区域中有针对性地设置的粗糙度来提供最优的和/或大的界面，从而为粘合剂提供相应的反应面。
根据本发明钢板的一个设计方案，钢板涂覆有金属的覆盖层，特别是通过热浸涂覆施加的基于锌的覆盖层。优选地，除了锌和不可避免的杂质外，该覆盖层还可以包含附加元素，如在覆盖层中的含量至高为5重量％的铝和/或含量至高为5重量％的镁。具有基于锌的覆盖层的钢板具有非常好的阴极腐蚀保护，这多年来在汽车制造中得到应用。如果提供了改进的腐蚀保护，则该覆盖层附加地具有含量为至少0.3重量％，特别是至少0.6重量％，优选至少0.9重量％的镁。铝可以相对于镁替代地或额外地以至少0.3重量％的含量存在，以尤其改进该覆盖层在该钢板处的连接，并且尤其在对该经涂覆的钢板进行热处理时基本上防止铁从该钢板扩散到覆盖层中，由此进一步获得积极的腐蚀特性。在此，覆盖层的厚度可以在1和15μm之间、尤其是2和12μm之间、优选地3和10μm之间。在最小限度以下不能确保足够的阴极腐蚀保护，并且在最高限度以上在连接根据本发明的钢板或由此制成的构件与另一构件时可出现接合问题，尤其是在超过覆盖层所给出的最高限度的厚度时不能确保在热接合或焊接时的稳定的工艺。在热浸涂覆中，首先用相应的覆盖层涂覆钢板，并且随后输送到精整。在钢板的热浸涂覆之后进行精整。
按照根据本发明钢板的一个备选的设计方案，钢板涂覆有金属覆盖层，特别是基于锌的覆盖层，其通过电解涂覆来施加。在此，覆盖层的厚度能够在1和10μm之间、尤其是1.5和8μm之间、优选地2和5μm之间。与热浸涂覆相比，钢板可首先被精整，随后被电解涂覆。取决于覆盖层厚度，基本上也可以在电解涂覆之后保持侧面区域中的粗糙度。替代地，也可以考虑首先电解涂覆和随后精整。
也可以考虑，不设置覆盖层、例如不设置金属的覆盖层。还可以考虑，例如在带材涂覆装置中，钢板涂有非金属的覆盖层，其中钢板在用非金属覆盖层涂覆之前或之后精整。
按照根据本发明的钢板的一种设计方案，尤其经涂覆的钢板还附加地设有过程介质，尤其设有油，其中，尤其具有至高2g/m2的覆层的过程介质容纳在表面结构中。由于表面结构的尺寸，仅存在对过程介质的很少需求，使得覆层被限制为至多2g/m2，特别地至多1.5g/m2，优选地至多1g/m2，优选地至多0.6g/m2，进一步优选地至多0.4g/m2。特别是通过粗糙度和与侧面区域中的相应的反应面相结合，过程介质在施加后基本上积聚在侧面区域中，并可选地积聚在表面结构的侧面区域和谷区域之间的过渡部处，并提供用于进一步的工艺，例如用于成形工艺，优选用于更靠近或邻近环绕成形工艺相关的位置的深拉工艺，以改进润滑并减少摩擦以及因此减少成形器件(例如成型装置)、优选深拉压力机的磨损。尤其可以有效地抑制过程介质在摩擦学上不利的区域上的沉积，这不利于过程介质导入实际的接触区或摩擦区。因此，根据本发明的具有较少过程介质需求的钢板具有非常好的摩擦学特性，并且与由现有技术已知的、尤其是涂油的钢板相比，尤其是由于较少的资源使用而对环境更友好。
根据第二方面，本发明涉及一种用于制造以确定性的表面结构精整的钢板的方法，该方法包括以下步骤：
提供钢板，
用精整辊对钢板进行精整，其中，作用在钢板表面上的精整辊的表面设有确定性的表面结构，使得在精整之后，该表面结构从钢板的表面出发冲压到钢板中，其中，该表面结构具有侧面区域，该侧面区域从表面出发延伸到谷区域，并且其中，至少该侧面区域具有大于20nm的粗糙度Ra。
精整辊的表面(正形状)通过在钢板的表面上的力的作用构造出表面结构，该表面结构限定了谷区域和侧面区域(负形状)，并基本上对应于精整辊的表面(正形状)。用于构造确定性的表面结构的精整辊可以利用合适的器件、例如借助于激光来加工，同样参见EP2 892 663B1。此外，也可以使用其它去除方法来设置精整辊处的表面，例如具有几何确定的或不确定的刃部的切削制造方法、化学或电子的、光学或等离子体感应的方法，这些方法适合于，能够对于具有表面结构的待精整的钢板执行，该钢板至少在侧面区域中具有大于20nm的粗糙度Ra。
为了避免重复，相应地参考关于根据本发明以确定性的表面结构精整的钢板的实施方案。
根据本发明的方法的一个设计方案，在提供钢板之前通过热浸涂覆对钢板进行涂覆。优选地，用于热浸涂覆的熔体除了锌和不可避免的杂质之外还可以含有附加的元素，例如含量至高5重量％的铝和/或含量至高5重量％的镁。
根据本发明的方法的另一设计方案，在精整钢板之后通过电解涂覆对已精整的钢板进行涂覆。
根据本发明的方法的一个设计方案，在精整之后，钢板还附加地设有过程介质，优选油，其中，该过程介质以至高为2g/m2的覆层，进一步优选至高为0.4g/m2的覆层施加。
附图说明
下面参照附图详细说明本发明的具体设计方案。附图和所得特征的伴随描述不应被理解为限于各个设计方案，而是用于说明示例性设计方案。此外，各个特征可以彼此间使用，也可以与上述描述的特征一起使用，用于本发明的可能的进一步扩展和改进，特别是在未示出的附加设计方案中。相同的部件始终设有相同的附图标记。
附图中：
图1)示出了根据本发明的实施例以确定性的表面结构精整的钢板的示意性局部剖视图，
图2a)、2b)和2c)中，分别在图2a)和2b)中示出根据现有技术在精整的钢板上的不同表面结构的示意性局部剖视图，以及在图2c)中示出了根据本发明的在精整的钢板上的表面结构，和
图3a)和3b)中，分别示出根据现有技术(图3a))以及根据本发明的实施例(图3b))的、经涂覆的、以确定性的表面结构精整的钢板的一部分的REM照片。
具体实施方式
图1示出了根据本发明的实施例以确定性的表面结构(2)精整的钢板(1、1’)的示意性局部剖视图。钢板(1、1’)可以是未经涂覆的钢板(1)，也就是说不具有尤其是金属的覆盖层或非金属的覆盖层，或者可以是用金属覆盖层(1.2)涂覆的钢板(1’)。表面结构(2)从钢板(1)的表面(1.1)出发冲压到钢板(1、1’)中，其中，表面结构(2)具有侧面区域(2.3)，该侧面区域从表面(1.1)出发延伸直至谷区域(2.2)。至少所述侧面区域(2.2)具有大于20nm的粗糙度Ra。根据去除方法，通过相应的在未示出的精整辊上的对应区域(正形状)设置侧面区域(2.3)和谷区域(2.2)，通过所述去除方法加工用于精整钢板(1、1’)的相应的精整辊(未示出)。此外，在图1中能够清楚地看到，表面结构(2)具有侧面区域(2.3)，该侧面区域从表面(1.1)出发延伸至谷区域(2.2)并且相对于钢板(1、1’)的垂线0以在1°与89°之间的角度(α)构造。环绕和构造表面结构(2)的侧面区域(2.3)与一体地联接或连接在侧面区域(2.3)上的谷区域(2.2)一起限定借助于精整冲压到钢板(1、1’)中的表面结构(2)的封闭的体积。
在图2a)、2b)和2c)中分别示出在经精整的钢板上的不同表面结构的示意性局部剖视图。
图2a)示出尤其是经涂覆的、以随机的表面结构精整的钢板的示意性局部剖视图，其中，表面结构借助于经EDT结构化的精整辊(未示出)精整。表面结构基本上完全被过程介质(M)、例如油填充或者覆盖。与其它两种设计方案(图2b)和2c))相比，对于过程介质(M)的需求更高，因为在EDT中，表面结构不是实施为封闭结构，而是实施为开放结构。
图2b)示出了尤其经涂覆的、以确定性的表面结构精整的钢板的示意性局部剖视图，其中，表面结构借助经激光结构化的精整辊(未示出)精整，参见EP 2 892 663 B1。与图2a)相比，可以使用更少的过程介质(M)，因为表面结构是封闭的。
根据本发明的尤其经涂覆的、以确定性的表面结构(2)精整的钢板(1、1’)的设计方案在图2c)中以局部剖视图示意性地示出，其中表面结构(2)借助于经激光结构化的精整辊(未示出)精整，同样参见EP 2 892 663 B1，然而具有的区别是，限制性地设置在作用到钢板(1、1’)和待产生的侧面区域(2.3)中的精整辊的表面处的正形状中的粗糙度，使得在经精整的钢板(1、1’)处在侧面区域(2.3)中设置具有大于20nm、尤其大于50nm、优选大于100nm、优选大于150nm、进一步优选大于200nm的粗糙度Ra的确定性的表面结构(2)。由此，与其他实施方案(图2a)和图2b))相比，可以进一步最小化对过程介质(M)的需求，并且可以将过程介质靠近或邻近与成形工艺相关的位置(1.1)地存储。
确定性的表面结构例如研究的是总反复出现的I形冲压部。其他实施形式也是可想到的和可应用的，并且不限于I形冲压部。在图3a)中示出了设有基于锌的覆盖层的板形貌的REM照片，其中表面结构借助于精整辊(未示出)冲压，其中精整辊的表面借助于激光结构化，参见EP 2 892 663 B1。在图3b)中示出了具有基于锌的覆盖层(1.2)的精整的钢板(1’)的形貌或确定性的表面结构(2)的REM照片，其中表面结构(2)借助于精整辊(未示出)冲压，其中精整辊的表面借助于激光结构化，参见EP 2 892 663 B1，然而区别在于，在作用于经涂覆的钢板(1’)和待产生的侧面区域(2.3)中的精整辊表面处的正形状的粗糙度Ra被限制地(definiert)设置。可以清楚地看到各个I结构的不同构造的侧面区域。
在根据图3b)的实施方案的示例中，对两个未经涂覆的和两个经热浸涂覆的钢板(1、1’)以确定性的表面结构进行精整。借助于原子力显微镜(AFM)对板材形貌的侧面区域进行研究。原子力显微镜的扫描区域具有90×90μm2的面积，其中测定在扫描范围内的20×2μm2面积的侧面区域中的粗糙度Ra。对于两个未经涂覆的、经精整的钢板(1)分别确定Ra＝45.99nm和Ra＝51.48nm的值，并且对于两个经涂覆的、经精整的钢板(1’分别确定Ra＝131.07nm和Ra＝205.40nm的值。
为了进一步研究，考虑四个经涂覆的、精整的钢板(V1至V4)。涂层的类型对于所有钢板选择为相同的，为在热浸涂覆工艺中施加的基于锌的涂层(锌和不可避免的杂质)，厚度为约7μm。V1和V2对应于本发明的钢板(1’)且V3和V4形成参照板。V3和V4与V1和V2的区别在于，V3和V4用以确定性表面结构和未限定的侧面区域的精整辊精整，参见实施方案图3a)。表1给出了根据本发明的钢板(1’)和参照板的对比。
表1
Figure BDA0003551270650000091
粗糙度Ra(算术平均粗糙度)的确定借助于在DIN EN ISO 4287中给出的方法来确定，并且在表中的数值的情况下涉及20×2μm2的面积，所述面积仅考虑侧面区域。钢板V3和V4的在侧面区域中的粗糙度Ra非常小。表1中关于带材拉伸测试的数据，根据DIN EN 1669的、在所有四个钢板V1至V4中在相同的条件下进行的杯拉伸试验，基本上显示了正面的结果。根据以下标准评价：
+++表示，没有任何明显的变薄，
++表示，在带材拉伸测试中测定的摩擦值以及在成型钢板的冲头边缘的出口处的变薄较小(低于初始钢板厚度5％的轻微变薄)，
+表示，在成形的钢板上的最小变薄超过初始钢板厚度的5％但低于初始钢板厚度的10％。
表1中关于根据DIN EN 1465的、对所有四个钢板V1至V4在相同条件下进行的拉伸剪切试验的数据显示了粘性能力方面的不同结果。断裂表现的评价根据DIN ENISO 10365进行，其中下文给出的数值借助于经验值确定。根据以下标准评价：
++表示，粘合的断裂面(其在拉伸剪切测试的范围中作为粘合剂中的断裂面而存在)的份额至少为85％，
+表示，粘合的断裂面(其在拉伸剪切测试的范围中作为粘合剂中的断裂面而存在)的份额为60％至小于85％，
0表示，粘合的断裂面(其在拉伸剪切测试的范围中作为粘合剂中的断裂面而存在)的份额为40％至小于60％。
此外，在根据本发明的经涂覆的、以确定性的表面结构精整的钢板V1和V2处的过程介质(M)的覆层降低到低于1g/m2，其中该量足以获得相应良好的结果。
