Abstract
本发明涉及热浸涂钢基材和用于制造该热浸涂钢基材的方法。
Description
本发明涉及热浸涂钢基材和用于制造该热浸涂钢基材的方法。本发明特别适用于汽车工业。
为了减轻车辆的重量，已知使用高强度钢来制造机动车辆。例如，为了制造结构零部件，必须改善这种钢的机械特性。已知添加合金元素以改善钢的机械特性。因此，生产并使用包括TRIP(相变诱发塑性)钢、DP(双相)钢和HSLA(高强度低合金)钢的高强度钢或超高强度钢，所述钢板具有高的机械特性。
通常，这些钢涂覆有改善诸如耐蚀性、可磷化性等特性的金属涂层。金属涂层可以在钢板的退火之后通过热浸涂来沉积。然而，对于这些钢，在连续退火线中进行的退火期间，对氧具有更高亲合性(与铁相比)的合金元素例如锰(Mn)、铝(Al)、硅(Si)或铬(Cr)氧化并导致在表面形成氧化物的层。这些氧化物为例如锰氧化物(MnO)或硅氧化物(SiO2)，其可以以连续膜的形式存在于钢板表面上，或者以不连续结核或小片的形式存在。它们妨碍待施加的金属涂层的适当附着，并且可能产生最终产品上没有涂层的区域或者与涂层分层相关的问题。
专利申请JP2000212712公开了用于制造包含0.02重量％或更多的P和/或0.2重量％或更多的Mn的镀锌钢板的方法，其中在非氧化性气氛下对钢板进行加热和退火，此后，将其浸入包含Al的镀锌浴中以进行镀锌，在退火之前将由1mg.m-2至200mg.m-2(作为转换成金属量的量)的范围内的选自Ni、Co、Sn和Cu基的金属化合物中的一种或更多种构成的涂层附着在钢板的表面上。
然而，上述专利申请中引用的钢板是低碳钢板，也称为常规钢板，包括IF钢(即无间隙钢)或BH钢(即烘烤硬化钢)。实际上，在实施例中，钢板包含非常少量的C、Si、Al，因此涂层附着在这些钢上。此外，仅测试了包含Ni、Co和Cu的预涂层。
因此，需要找到一种方法来改善高强度钢和超高强度钢(即包含一定量合金元素的钢基材)的润湿性和涂层附着性。
因此，本发明的目的是提供具有包含合金元素的化学组成的涂覆的钢基材，其中润湿性和涂层附着性得到大幅改善。另一个目的是提供易于实施的用于制造所述涂覆的金属基材的方法。
该目的通过提供根据权利要求1至13中任一项的涂覆的金属基材来实现。
另一个目的通过提供根据权利要求14至27中任一项的用于制造该涂覆的钢基材的方法来实现。
最后，目的通过提供根据权利要求28的涂覆的钢基材的用途来实现。
根据本发明的以下详细描述，本发明的其他特征和优点将变得明显。
将定义以下术语：
-“重量％”意指重量百分比。
本发明涉及热浸涂钢基材，所述热浸涂钢基材涂覆有Sn的层，所述Sn的层被基于锌或铝的涂层直接覆盖，所述钢基材按重量百分比计具有以下化学组成：
0.10≤C≤0.4％，
1.2≤Mn≤6.0％，
0.3≤Si≤2.5％，
Al≤2.0％，
以及在完全任选的基础上，诸如以下的一种或更多种元素：
P＜0.1％，
Nb≤0.5％，
B≤0.005％，
Cr≤1.0％，
Mo≤0.50％，
Ni≤1.0％，
Ti≤0.5％，
组成的剩余部分由铁和由加工产生的不可避免的杂质构成，所述钢基材在从钢基材的表面延伸多至10μm的区域中还包含0.0001重量％至0.01重量％的Sn。
不希望被任何理论束缚，似乎特定的钢基材特别是在再结晶退火期间具有大幅改变的表面。特别地，认为通过吉布斯机制，Sn在钢基材的表面层的10μm以内的区域中偏析，减小了钢基材的表面张力。此外，在钢基材上仍存在Sn的薄单层。因此，似乎选择性氧化物以结核的形式存在于钢基材表面，而不是允许高润湿性和高涂层附着性的选择性氧化物的连续层。
关于钢的化学组成，碳量为0.10重量％至0.4重量％。如果碳含量小于0.10％，则存在拉伸强度不足的风险，例如低于900MPa。此外，如果钢显微组织包含残余奥氏体，则可能无法获得实现足够的延伸率所必需的其稳定性。高于0.4％的C，使可焊性降低，因为在点焊的热影响区或熔区中产生低韧性显微组织。在一个优选的实施方案中，碳含量在0.15％至0.4％的范围内，更优选地在0.18％至0.4％的范围内，这使得可以实现高于1180MPa的拉伸强度。
锰是固溶硬化元素，其有助于获得高拉伸强度，例如高于900MPa。当Mn含量为至少1.2重量％时，获得这种效果。然而，高于6.0％，Mn添加可能促成形成具有过于明显的偏析带的结构，这可能不利地影响焊缝机械特性。优选地，锰含量在2.0％至5.1％的范围内，更优选地在2.0％至3.0％的范围内以实现这些效果。
硅必须以0.3重量％至2.5重量％，优选地0.5重量％至1.1重量％、或1.1重量％至3.0重量％，更优选地1.1重量％至2.5重量％，并且有利地1.1重量％至2.0重量％的Si包含在内以实现所需的机械特性和可焊性的组合：由于硅在渗碳体中的低溶解度，并且由于该元素使奥氏体中碳的活性增加的事实，硅减少了在板的冷轧之后退火期间碳化物的析出。
铝必须小于或等于2.0％，优选地大于或等于0.5％，更优选地大于或等于0.6％。对于残余奥氏体的稳定化，铝具有与硅的影响相对相似的影响。优选地，当Al的量大于或等于1.0％时，Mn的量大于或等于3.0％。
钢可以任选地包含实现析出硬化的元素，例如P、Nb、B、Cr、Mo、Ni和Ti。
P被认为是由炼钢产生的残留元素。其可以以<0.1重量％的量存在。
钛和铌也是可以任选地用于通过形成析出物来实现硬化和强化的元素。然而，当Nb或Ti含量大于0.50％时，存在过度析出可能引起韧性降低的风险，这必须避免。优选地，Ti的量为0.040重量％至0.50重量％、或0.030重量％至0.130重量％。优选地，钛含量为0.060重量％至0.40重量％，例如0.060重量％至0.110重量％。优选地，Nb的量为0.070重量％至0.50重量％、或0.040重量％至0.220重量％。优选地，铌含量为0.090重量％至0.40重量％，并且有利地为0.090重量％至0.20重量％。
钢还可以任选地以小于或等于0.005％的量包含硼。通过在晶界处偏析，B使晶界能降低并因此有益于增加抗液态金属脆化性。
铬使得可以在退火周期期间在保持在最高温度之后的冷却步骤期间延迟先共析铁素体的形成，使得可以实现更高的强度水平。因此，出于成本和防止过度硬化的原因，铬含量小于或等于1.0％。
量小于或等于0.5％的钼对于提高淬透性和使残余奥氏体稳定是有效的，因为该元素使奥氏体的分解延迟。
钢可以任选地以小于或等于1.0％的量包含镍以改善韧性。
优选地，在从钢基材的表面延伸多至10μm的区域中，钢基材包含小于0.005重量％并且有利地小于0.001重量％的Sn。
优选地，Sn的层的涂层重量为0.3mg.m-2至200mg.m-2，更优选地为0.3mg.m-2至150mg.m-2，有利地为0.3mg.m-2至100mg.m-2，例如为0.3mg.m-2至50mg.m-2。
优选地，钢基材显微组织包含铁素体、残余奥氏体以及任选地马氏体和/或贝氏体。
优选地，钢基材的拉伸应力大于500MPa，优选地为500MPa至2000MPa。有利地，延伸率大于5％，优选地为5％至50％。
在一个优选的实施方案中，基于铝的涂层包含小于15％的Si，小于5.0％的Fe，任选地0.1％至8.0％的Mg和任选地0.1％至30.0％的Zn，剩余部分为Al。
在另一个优选的实施方案中，基于锌的涂层包含0.01％至8.0％的Al，任选地0.2％至8.0％的Mg，剩余部分为Zn。更优选地，基于锌的涂层包含0.15重量％至0.40重量％的Al，余量为Zn。
熔浴还可以包含不可避免的杂质以及来自进给锭或来自钢基材在熔浴中的路径的残余元素。例如，任选的杂质选自Sr、Sb、Pb、Ti、Ca、Mn、Sn、La、Ce、Cr、Zr或Bi，每种另外的元素的按重量计的含量小于0.3重量％。来自进给锭或来自钢基材在熔浴中的路径的残余元素可以为铁，其含量高至5.0重量％，优选地3.0重量％。
本发明还涉及用于制造热浸涂钢基材的方法，所述方法包括加热段、均热段、冷却段、任选地均衡段，这样的方法包括以下步骤：
A.提供具有根据本发明的化学组成的钢基材，
B.沉积由Sn构成的涂层，
C.对步骤B)中获得的预涂覆的钢基材进行再结晶退火，所述再结晶退火包括以下子步骤：
i.在具有气氛A1的加热段中将预涂覆的钢基材加热，所述气氛A1包含小于8体积％的H2和至少一种不活泼气体，其露点DP1低于或等于-45℃，
ii.在具有气氛A2的均热段中将钢基材均热，所述气氛A2包含小于30体积％的H2和至少一种不活泼气体，其露点DP2低于或等于-45℃，
iii.在冷却段中将钢基材冷却，
iv.任选地，在均衡段中将钢基材均衡，以及
D.用基于锌或铝的涂层进行热浸涂。
不希望被任何理论束缚，认为如果气氛包含大于8体积％和/或DP高于-45℃，则似乎在再结晶退火期间由于薄的还原而形成水。认为水与钢的铁反应以形成覆盖钢基材的铁氧化物。因此，存在无法控制选择性氧化的风险，并因此选择性氧化物以连续层的形式存在于钢基材上，使润湿性显著降低。
优选地，在步骤B)中，由Sn构成的涂层通过电镀、化学镀、渗碳、辊涂(roll coat)或真空沉积来沉积。优选地，Sn涂层通过电沉积来沉积。
优选地，在步骤B)中，由Sn构成的涂层的涂层重量为0.6mg.m-2至300mg.m-2，优选地为6mg.m-2至180mg.m-2，更优选地为6mg.m-2至150mg.m-2。例如，由Sn构成的涂层的涂层重量为120mg.m-2，更优选地为30mg.m-2。
优选地，在步骤C.i)中，将预涂覆的钢基材从环境温度加热至700℃至900℃的温度T1。
有利地，在步骤C.i)中，在包含不活泼气体和H2的气氛中进行均热，所述H2的量小于或等于7体积％，更优选地小于3体积％，有利地小于或等于1体积％，更优选地小于或等于0.1体积％。
在一个优选的实施方案中，加热包括预加热段。
优选地，在步骤C.ii)中，将预涂覆的钢基材在700℃至900℃的温度T2下均热。
例如，在步骤C.ii)中，H2的量小于或等于20体积％，更优选地小于或等于10体积％，有利地小于或等于3体积％。
有利地，在步骤C.i)和C.ii)中，DPI和DP2彼此独立地低于或等于-50℃，更优选地低于或等于-60℃。例如，DPI和DP2可以相等或不同。
优选地，在步骤C.iii)中，将预涂覆的钢基材从T2冷却至400℃至500℃的温度T3，T3为浴温。
有利地，冷却在气氛A3中进行，所述气氛A3包含小于30体积％的H2和不活泼气体，其露点DP3低于或等于-30℃。
任选地，在具有气氛A4的均衡段中将钢基材从温度T3均衡至400℃至700℃的温度T4，所述气氛A4包含小于30体积％的H2和不活泼气体，其露点DP4低于或等于-30℃。
优选地，在步骤C.i)至C.iv)的所有步骤中，至少一种不活泼气体选自：氮气、氩气和氦气。例如，再结晶退火在包括直接火焰炉(direct flame furnace，DFF)和辐射管式炉(radiant tube furnace，RTF)的炉中或者在全RTF中进行。在一个优选的实施方案中，再结晶退火在全RTF中进行。
