Description

一种取代金靶的玫瑰金色系调试镀膜技术
技术领域
本发明涉及的是真空镀膜技术领域，具体涉及一种取代金靶的玫瑰金色系调试镀膜技术。
背景技术
PVD(Physical Vapor Deposition)即物理气相沉积，是指在真空条件下，利用气体放电使金属靶材蒸发并使被蒸发物质与气体都发生电离，利用电场的加速作用，使被蒸发物质及其反应产物沉积在工件上。PVD技术是当前广泛应用的表面处理技术，PVD工艺过程是一个极为复杂的物理化学过程，包括汽化(激光、热、离子法、电子束、离子束)、阴极真空喷镀和离子电镀。
在闪闪发光的黄金饰品与经典高雅的铂金饰品之后，色调柔和迷人的玫瑰金饰品渐成为时尚人士的“新宠”， 近几年在金属装饰行业非常流行，玫瑰金颜色以她特有的风格与文化，演绎出贵金属饰品的又一片崭新天地，通常玫瑰金由75%的黄金与其它合金组成(俗称三色金)，目前市面上很多品牌都采用PVD在金属产品上沉积玫瑰金涂层的方式进行，行业内叫IP玫瑰金。玫瑰金镀层一般有仿金层和玫瑰金层构成，底层的仿金层一般为TiCN，主要是增加玫瑰金的硬度和耐磨度，面层的玫瑰金是靠溅射金靶形成的。可以看出目前玫瑰金颜色层需要使用金靶溅射成膜，而金靶价格昂贵，平均达400元/克，使得产品的加工成本过高，得不偿失 。
因此，开发一款更为实用性、性价比高的真空磁控溅射镀膜工艺尤为必要。
发明内容
针对现有技术上存在的不足，本发明目的是在于提供一种取代金靶的玫瑰金色系调试镀膜技术，大大降低加工成本，实用性强，性价比高，制备的膜层硬度高，耐磨性高，耐腐蚀性好，化学稳定性强，易于推广使用。
为了实现上述目的，本发明是通过如下的技术方案来实现：一种取代金靶的玫瑰金色系调试镀膜技术，在基片上层依次通过真空磁控溅射的方法分别镀Cr打底层、TiCrN过渡层、TiN过渡层、TiCN颜色层，最终使表面呈现玫瑰金色，其工艺步骤如下：
①在基片的表面通过真空磁控溅射沉积技术制备Cr打底层，加强基体与膜层的结合力，防止掉膜；
②在第一层Cr打底层的表面产生一层TiCrN过渡层，为下一道工序铬靶灭靶、钛靶点靶做准备，保持膜层的连续性；
③在第二层TiCrN过渡层的基础上，通过真空磁控溅射沉积技术镀TiN过渡层，经过多个工序提升氮气通入量，与钛靶溅射沉积多层递进的过渡膜层，提高膜层颜色的均一性；
④通过真空磁控溅射溅射沉积技术，使用氮气、乙炔与钛靶结合在第三层TiN过渡层的表面镀TiCN颜色层，使产品表面呈现玫瑰金色，达到装饰作用。
作为优选，所述的步骤①中基片采用不锈钢或硬质合金基体，基片在镀Cr打底层之前经过CNC、抛光、超声波清洗制程，使得基体表面光滑、清洁，便于膜层的沉积，以及最终成品的光亮。
本发明的有益效果：本技术制备的每层膜都能起到不同的功能性与颜色过渡的作用，不仅大大降低加工成本，实用性强，性价比高，且该种膜层具有高硬度、高耐磨性、很好的耐腐蚀性和化学稳定性的特点，通过各个膜层的颜色递进能够大幅度提高工件的外观装饰性能，应用前景广阔。
附图说明
下面结合附图和具体实施方式来详细说明本发明；
图1为本发明制备的玫瑰金膜的结构示意图。
具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施方式，进一步阐述本发明。
参照图1，本具体实施方式采用以下技术方案：一种取代金靶的玫瑰金色系调试镀膜技术，在基片1上层依次通过真空磁控溅射的方法分别镀Cr打底层2、TiCrN过渡层3、TiN过渡层4、TiCN颜色层5，最终使表面呈现玫瑰金色，其工艺步骤如下：
①基片1采用不锈钢或硬质合金基体，基片1在镀Cr打底层2之前经过CNC、抛光、超声波清洗制程，使得基体表面光滑、清洁，便于膜层的沉积，以及最终成品的光亮；在基片1的表面通过真空磁控溅射沉积技术制备Cr打底层2，加强基体与膜层的结合力，防止掉膜；
②在第一层Cr打底层2的表面产生一层TiCrN过渡层3，为下一道工序铬靶灭靶、钛靶点靶做准备，保持膜层的连续性；
③在第二层TiCrN过渡层3的基础上，通过真空磁控溅射沉积技术镀TiN过渡层4，经过多个工序提升氮气通入量，与钛靶溅射沉积多层递进的过渡膜层，提高膜层颜色的均一性；
④通过真空磁控溅射溅射沉积技术，使用氮气、乙炔与钛靶结合在第三层TiN过渡层4的表面镀TiCN颜色层5，使产品表面呈现玫瑰金色，达到装饰作用。
本具体实施方式制备而成的玫瑰金膜由基片1、Cr打底层2、TiCrN过渡层3、TiN过渡层4、TiCN颜色层5组成，各层的技术优势在于：
(1)Cr打底层2可有效防止膜层脱落，使膜层具有卓越的附着力，相较于电镀、喷涂，可以折弯90度以上不发生裂化或者剥落。
(2)TiCrN过渡层3与TiN过渡层4的结合使膜层整体颜色深韵、光亮,颜色均匀一致。
(3)TiCN颜色层5在常规环境下，户内或者户外，都抗氧化，不褪色，不失去光泽并不留下痕迹，正常的使用情况下不会破损。
(4)钛合金膜层在潮湿的大气和海水介质中工作，其抗蚀性远优于不锈钢；对点蚀、酸蚀、应力腐蚀的抵抗力特别强；对碱、氯化物、氯的有机物品、硝酸、硫酸等有优良的抗腐蚀能力。
本具体实施方式采用的TiCN膜层相较于传统金靶溅射形成的玫瑰金膜层，其热强度高、抗蚀性好，具有低温性能好、环保性能好、耐久度好和导热弹性小的特点，每层膜都能起到不同的功能性与颜色过渡的作用，不仅大大降低加工成本，同时通过各个膜层的颜色递进也能够大幅度提高工件的外观装饰性能，具有广阔的市场应用前景。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
