Preparation and Properties of CrCu Functional Decorative Coating on ABS Substrate

  • 摘要: 丙烯腈-丁二烯-苯乙烯(简称为ABS)的密度低、柔韧性好、易于机械加工、成本低,已被广泛应用于汽车、卫浴、家电等领域。为改善传统ABS表面电镀金属化改性技术的不足,本文采用具有干式、绿色特点的双靶磁控溅射镀膜技术,在ABS表面设计制备了CrCu复合改性涂层,重点研究了Cu含量对涂层组分结构、色泽、力学及耐候性能的影响。结果表明,调控Cu靶溅射电流从0.5 A增加到2 A,CrCu复合涂层中的铜含量在15.2-48.3%(质量比)之间变化,且所有涂层呈柱状生长结构,Cu主要以固溶形式弥散分布在Cr(110)的主相晶格结构中。随着Cu含量增加,CrCu复合涂层从纯Cr涂层银白色逐渐变为浅紫红色,涂层弹性模量也随之下降,与基材弹性模量匹配更好;但因Cu元素含量过高,复合涂层硬度降低。另外,Cr涂层中Cu的引入能够提高ABS表面金属涂层的耐候性。
    Abstract: Acrylonitrile-butadiene-styrene (referred to as ABS) with low density,good flexibility,easy machining,low cost,has been widely used in automotive,sanitary ware,household appliances and other fields.In order to improve the shortcomings of the traditional electroplating metallization modification technology on ABS surface this study adopted the dual-target magnetron sputtering coating technology with dry and eco-friendly characteristics to design and prepare CrCu composite modified coating on ABS surface.The effect of Cu content on the composition structure,color,mechanics and weather resistance of the coating was studied.The results showed that the content of Cu in the CrCu composite coating varied from 15.2 to 48.3 at.%when the sputtering current of the Cu target increased from 0.5A to 2A.All the coatings had a columnar growth structure,and Cu was mainly distributed in the lattice structure of Cr (110) in the form of a solid solution.With the increase of Cu content,the CrCu composite coating gradually changed from pure Cr coating silver white to light purple red,and the elastic modulus of the coating decreased,which was better matched with the elastic modulus of the substrate.However,due to the high content of Cu element,the hardness of composite coating decreased.In addition,the introduction of Cu in Cr coating can improve the weather resistance of metal coating on ABS surface.
