只看楼主收藏回复

PVD(物理气相沉积)镀膜技术主要分为三类,真空蒸发镀膜、真空溅射镀和真空离子镀膜。对应于PVD技术的三个分类,相应的真空镀膜设备也就有真空蒸发镀膜机、真空溅射镀膜机和真空离子镀膜机这三种。近十多年来,真空离子镀膜技术的发展是快的,它已经成为当今先进的表面处理方式之一。我们通常所说的PVD镀膜,指的就是真空离子镀膜;通常所说的PVD镀膜机,指的也就是真空离子镀膜机。
PVD镀膜(离子镀膜)技术,其具体原理是在真空条件下,采用低电压、大电流的电弧放电技术,利用气体放电使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镀膜膜层的特点,采用PVD镀膜技术镀出的膜层,具有高硬度、高耐磨性(低摩擦系数)、很好的耐腐蚀性和化学稳定性等特点,膜层的寿命更长;同时膜层能够大幅度提高工件的外观装饰性能。
PVD镀膜能够镀出的膜层种类,PVD镀膜技术是一种能够真正获得微米级镀层且无污染的环保型表面处理方法,它能够制备各种单一金属膜(如铝、钛、锆、铬等),氮化物膜(TiN、ZrN、CrN、TiAlN)和碳化物膜(TiC、TiCN),以及氧化物膜(如TiO等)。PVD镀膜膜层的厚度—PVD镀膜膜层的厚度为微米级,厚度较薄,一般0.3μm~5μm,其中装饰镀膜膜层的厚度一般为0.3μm~1μm,因此可以在几乎不影响工件原来尺寸的情况下提高工件表面的各种物理性能和化学性能,镀后不须再加工。
PVD镀膜能够镀出的膜层的颜色种类—PVD镀膜目前能够做出的膜层的颜色有深金黄色,浅金黄色,咖啡色,古铜色,灰色,黑色,灰黑色,七彩色等。通过控制镀膜过程中的相关参数,可以控制镀出的颜色;镀膜结束后可以用相关的仪器对颜色进行测量,使颜色得以量化,以确定镀出的颜色是否满足要求。
PVD镀膜与传统化学电镀(水电镀)的异同PVD镀膜与传统的化学电镀的相同点是,两者都属于表面处理的范畴,都是通过一定的方式使一种材料覆盖在另一种材料的表面。两者的不同点是:PVD镀膜膜层与工件表面的结合力更大,膜层的硬度更高,耐磨性和耐腐蚀性更好,膜层的性能也更稳定;PVD镀膜不会产生有毒或有污染的物质。
PVD镀膜技术目前主要应用的行业,PVD镀膜技术的应用主要分为两大类:装饰镀膜和工具镀膜。装饰镀的目的主要是为了改善工件的外观装饰性能和色泽同时使工件更耐磨耐腐蚀延长其使用寿命;这方面主要应用五金行业的各个领域,如门窗五金、锁具、卫浴五金等行业。工具镀的目的主要是为了提高工件的表面硬度和耐磨性,降低表面的摩擦系数,提高工件的使用寿命;这方面主要应用在各种刀剪、车削刀具(如车刀、刨刀、铣刀、钻头等等)、各种五金工具(如螺丝刀、钳子等)、各种模具等产品中。
PVD镀膜(离子镀膜)技术的主要特点和优势—和真空蒸发镀膜真空溅射镀膜相比较,PVD离子镀膜具有如下优点:
A.膜层与工件表面的结合力强,更加持久和耐磨
B.离子的绕射性能好,能够镀形状复杂的工件0v+R0S4
C.膜层沉积速率快,生产效率高

PVD技术的发展
PVD技术出现于二十世纪七十年代末,制备的薄膜具有高硬度、低摩擦系数、很好的耐磨性和化学稳定性等优点。在高速钢刀具领域的成功应用引起了世界各国制造业的高度重视,人们在开发高性能、高可靠性涂层设备的同时,也在硬质合金、陶瓷类刀具中进行了更加深入的涂层应用研究。
与CVD工艺相比,PVD工艺处理温度低,在600℃以下时对刀具材料的抗弯强度无影响;薄膜内部应力状态为压应力,更适于对硬质合金精密复杂刀具的涂层;PVD工艺对环境无不利影响,符合现代绿色制造的发展方向。目前PVD涂层技术已普遍应用于硬质合金立铣刀、钻头、阶梯钻、油孔钻、铰刀、丝锥、可转位铣刀片、异形刀具、焊接刀具等的涂层处理。
PVD技术不仅提高了薄膜与刀具基体材料的结合强度,涂层成分也由第1代的TiN发展为TiC、TiCN、ZrN、CrN、MoS2、TiAlN、TiAlCN、TiN-AlN、cnx、DLC和ta-C等多元复合涂层。

PVD coating technology and PVD coating machine in mobile phone industry
PVD (physical vapor deposition) coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Corresponding to the three categories of PVD technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In recent ten years, the development of vacuum ion coating technology is fast. It has become one of the advanced surface treatment methods. PVD coating, as we usually call it, refers to vacuum ion coating; PVD coating machine usually refers to vacuum ion coating machine.
The specific principle of PVD coating (ion coating) technology is that under vacuum conditions, the arc discharge technology with low voltage and high current is adopted, the gas discharge is used to evaporate the target and ionize the evaporated material and gas, and the evaporated material and its reaction products are deposited on the workpiece by using the acceleration of electric field.
The characteristics of PVD coating. The coating plated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the service life of the coating is longer; At the same time, the film can greatly improve the appearance decoration performance of the workpiece.
PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (tin, ZrN, CrN, TiAlN), carbide films (TIC, TiCN), and oxide films (such as TiO, etc.). Thickness of PVD coating layer - the thickness of PVD coating layer is micron, and the thickness is relatively thin, generally 0.3 μ m~5 μ m. The thickness of decorative coating is generally 0.3 μ m~1 μ m. Therefore, various physical and chemical properties of the workpiece surface can be improved without affecting the original size of the workpiece, and there is no need to process after plating.
Color types of PVD coating - at present, the colors of PVD coating can include dark golden yellow, light golden yellow, coffee, bronze, gray, black, gray black, seven colors, etc. The color of the coating can be controlled by controlling the relevant parameters in the coating process; After coating, the color can be measured with relevant instruments to quantify the color, so as to determine whether the plated color meets the requirements.
Similarities and differences between PVD coating and traditional chemical plating (water plating). The similarities between PVD coating and traditional chemical plating are that they both belong to the category of surface treatment, and make one material cover the surface of another material in a certain way. The differences between the two are: PVD coating has greater adhesion to the workpiece surface, higher hardness, better wear resistance and corrosion resistance, and more stable performance; PVD coating will not produce toxic or polluting substances.
At present, PVD coating technology is mainly used in industries. The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The purpose of decorative plating is to improve the appearance, decorative performance and color of the workpiece, make the workpiece more wear-resistant and corrosion-resistant, and prolong its service life; This aspect is mainly used in various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware and other industries. The purpose of tool plating is to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface and improve the service life of the workpiece; This aspect is mainly used in various cutters, turning tools (such as turning tools, planers, milling cutters, drill bits, etc.), various hardware tools (such as screwdrivers, pliers, etc.), various molds and other products.
Main features and advantages of PVD coating (ion coating) - compared with vacuum evaporation coating and vacuum sputtering coating, PVD ion coating has the following advantages:
A. The adhesion between the film and the workpiece surface is strong, more durable and wear-resistant
B. The ion diffraction performance is good, and the workpiece 0V + r0s4 with complex shape can be plated
C. The film deposition rate is fast and the production efficiency is high
D. A wide variety of coatings can be coated
E. The film has stable performance and high safety (it has obtained FDA certification and can be implanted into human body
Development of PVD Technology
PVD technology appeared in the late 1970s. The prepared films have the advantages of high hardness, low friction coefficient, good wear resistance and chemical stability. The successful application in the field of high-speed steel cutting tools has attracted great attention in the manufacturing industry all over the world. While developing high-performance and high reliability coating equipment, people have also carried out more in-depth coating application research in cemented carbide and ceramic cutting tools.
Compared with CVD process, PVD process has lower treatment temperature and has no effect on the bending strength of tool material below 600 ℃; The internal stress state of the film is compressive stress, which is more suitable for the coating of cemented carbide precision and complex tools; PVD process has no adverse impact on the environment and is in line with the development direction of modern green manufacturing. At present, PVD coating technology has been widely used in the coating treatment of cemented carbide end mills, drills, step drills, oil hole drills, reamers, taps, indexable milling inserts, special-shaped tools, welding tools, etc.
PVD technology not only improves the bonding strength between film and tool matrix material, but also develops the coating composition from the first generation tin to multicomponent composite coatings such as tic, TiCN, ZrN, CrN, MoS2, TiAlN, tialcn, tin AlN, CNx, DLC and ta-c.

Nowadays, PVD has been quite popular in the field of daily hardware, and many hardware manufacturers have begun the development and mass production of PVD products. PVD's rich colors make it very easy to match. Its excellent resistance to harsh environment, easy cleaning and non fading performance make it deeply loved by consumers. In particular, copper series coatings are widely used all over the world to replace copper and plating.
