Description

镁合金表面防腐处理方法及其镁制品
技术领域
本发明涉及一种镁合金表面防腐处理方法及其镁制品。
背景技术
镁合金具有质量轻、散热性能好等优点,在通讯、电子、交通运输、建筑及航天航空等领域应用广泛。然而,由于镁合金的化学活性较高,在空气中很容易氧化,生成疏松、保护能力差的氧化膜,导致镁合金在潮湿的大气、土壤和海水中容易发生严重腐蚀,导致使用镁合金制作的产品的寿命缩短,阻碍了镁合金的广泛应用。
为了提高镁合金的耐腐蚀性能,通常需要对镁合金表面进行表面成膜处理,常见的处理手段有阳极氧化处理、烤漆等,但这些工艺都存在较大的环境污染问题。而真空镀膜(PVD)技术虽是一种非常环保的镀膜工艺,且可镀制的膜层种类丰富、耐磨性能优异,但当承镀基体表面具有微观凹陷或空隙时,PVD工艺沉积的膜层通常具有基体表面的仿形结构,且沉积于这些凹陷或空隙内的膜层往往其它区域的要薄,所以在使用过程中,所述凹陷或空隙区域往往更容易发生点蚀,使膜层无法有效地防止镁合金基体被防腐。
发明内容
有鉴于此,有必要提供一种可效提高镁合金防腐性能的防腐处理方法。
另外,还有必要提供一种由上述方法制得的镁制品。
一种镁合金表面防腐处理方法,包括以下步骤:
提供镁合金基体;
对镁合金基体进行化学除油;
用植物油酸为成膜剂的溶液对镁合金基体进行化学转化处理,以于镁合金基体上形成一层植物油酸转化膜;
通过真空镀膜方法在该植物油酸转化膜上形成由难熔化合物组成的陶瓷涂层。
由上述镁合金表面防腐处理方法所获得的镁制品,包括镁合金基体、形成于镁合金基体表面的植物油酸转化膜及形成于该植物油酸转化膜上的由难熔化合物组成的陶瓷涂层。
其中,该植物油酸转化膜经用植物油酸为成膜剂的溶液对镁合金基体进行化学转化处理而形成。
本发明的镁合金表面防腐处理方法先通过化学转化处理于镁合金基体上制备一层植物油酸转化膜,然后于该植物油酸转化膜上镀覆耐磨陶瓷涂层。其中该植物油酸转化膜一方面将镁合金基体表面平整化,另一方面植物油酸转化膜自身结构致密,阻挡性好,化学稳定性高,与镁合金基体结合力强,具有良好的防腐功能。而外层耐磨的陶瓷涂层,可保护植物油酸转化膜不易受到机械损伤。因此,经该方法处理的镁制品具有良好的抗腐蚀性能。

具体实施方式
本发明较佳实施例镁合金表面防腐处理方法包括如下步骤:
请参阅图1,提供镁合金基体20。
对镁合金基体20进行化学除油。化学除油是将镁合金基体20浸渍于60-80℃的除油溶液中30-60s。所用除油溶液为含25-30g/L碳酸钠(Na2CO3)、20-25g/L磷酸三钠(Na3PO4·12H2O)及1-3g/L乳化剂的水溶液,其中所述乳化剂可用OP-10乳化剂,其主要组分为烷基酚与环氧乙烷的缩合物。
对镁合金基体20进行碱蚀处理。该碱蚀处理步骤是将镁合金基体20浸渍于40-50℃的碱性蚀刻液中3-5s。所用碱性蚀刻液为含40-70g/L氢氧化钠(NaOH)、10-20g/LNa3PO4·12H2O、25-30g/LNa2CO3及40-50g/L氟化钠(NaF)的水溶液。该碱蚀处理一方面用于消低镁合金基体20上突出的部位,使镁合金基体20表面趋于平整,另一方面可进一步去除镁合金基体20表面的油污,
接着可对镁合金基体20进行活化处理。该活化处理步骤是将镁合金基体20浸渍于含质量百分比浓度为1%-3%HF的水溶液中3-5s,以去除镁合金基体20因暴露于空气中的时间过长而在表面形成的氧化膜,使镁合金基体20表面被活化。
用植物油酸(也称顺-9-十八碳烯酸)为成膜剂的溶液对镁合金基体20进行化学转化处理,以于镁合金基体20上形成植物油酸转化膜30。
该化学转化处理所用溶液配方可为含10-30ml/L植物油油酸及酮类化合物的水溶液,其中该酮类化合物用于促进植物油酸的溶解,该植物油酸溶液的pH值为2-5。较佳地,该植物油酸溶液为含15ml/L及丙酮的水溶液,其pH值为2.8。处理方法可将经上述碱蚀处理的镁合金基体20浸泡于30-50℃的该植物油酸溶液中2-4分钟,浸泡过程中可搅拌溶液。较佳地,浸泡过程中该植物油酸溶液的温度保持为35℃,浸泡时间为2.5分钟。
然后,对形成有所述植物油酸转化膜30的镁合金基体20进行真空镀膜处理,以在植物油酸转化膜30上形成由难熔化合物组成的陶瓷涂层40。该陶瓷涂层40包括一层或多层金属难熔化合物层,该金属难熔化合物可选自钛、铝、铬、锆及钴的氮化物、氧化物、氮碳化物及氮氧化物中的一种或几种的组合。本实施例中,该陶瓷涂层40包括一层氧化铝(Al2O3)层42及一层氮氧化铬(CrON)层43,该氧化铝层42直接形成于该植物油酸转化膜30上,该氮氧化铬层43形成于该氧化铝层42上。

在该植物油酸转化膜30上溅射该氧化铝层42。将形成有该植物油酸转化膜30的镁合金基体20放置于磁控溅射设备1的转架4上,对真空室2抽真空至6.0×10-3~8.0×10-3Pa后通入溅射气体氩气,氩气流量为150~300sccm(标准状态毫升/分钟),同时通入反应气体氧气,氧气流量为50~90sccm,镁合金基体20施加偏压至-100~-300V,开启铝靶5,铝靶5的功率为8~10kw,调节真空室2内温度为100~150℃,转架4的转速为0.5~1.0rpm(revolution perminute,转/分钟),溅射0.5~1小时,以于植物油酸转化膜30表面形成该氧化铝层42。
在氧化铝层42上溅射该氮氧化铬层43。关闭铝靶5,开启铬靶6,铬靶6的功率为8~10kw,调节氧气流量为40~100sccm,氮气流量为30~60sccm,其它参数保持不变,溅射0.5~2小时,以在该氧化铝层42上沉积一层氮氧化铬层43。
镀膜结束后,关闭负偏压及铬靶6电源,停止通入氩气和反应气体,待所述氮氧化铬层43冷却后,向真空室2内通入空气,打开真空室门,取出镀覆好的镁制品10。
