PVD是英文PhysicalVaporDeposition的缩写,中文意思是“物理气相沉积”,是指在真空条件下,用物理的方法使材料沉积在被镀工件上的薄膜制备技术。

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最快的,它已经成为当今比较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,一般为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优先域,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 is the abbreviation of physical vapor deposition in English, which means "physical vapor deposition" in Chinese. It refers to the thin film preparation technology that makes materials deposited on the plated workpiece by physical method under vacuum condition.

PVD coating and PVD coating machine

PVD (physical vapor deposition) coating technology can be 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 also has three kinds of vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In recent ten years, the development of vacuum ion plating technology is the fastest, it has become one of the most advanced surface treatment methods. PVD coating refers to vacuum ion coating; PVD coating machine refers to vacuum ion coating.

decorative coating

PVD coating (ion coating) technology, the specific principle of which is to use the arc discharge technology of low voltage and high current under the vacuum condition, use the gas discharge to make the target evaporate and ionize the evaporated substance and gas, and use the acceleration of electric field to make the evaporated substance and its reaction products deposit on the workpiece.

The characteristics of PVD coating, the coating 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 coating can greatly improve the appearance and decoration performance of the workpiece.

PVD coating technology is a kind of environmental protection surface treatment method that can truly obtain micron level coating and no 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 - the thickness of PVD coating is micrometer level, which is relatively thin, generally 0.3 μ m ~ 5 μ m, among which the thickness of decorative coating is generally 0.3 μ m ~ 1 μ m, so it can improve the physical and chemical properties of the workpiece surface without affecting the original size of the workpiece, and it does not need to be processed after plating.

The color types of the film that can be plated by PVD coating - the color of the film that can be made by PVD coating at present includes dark golden yellow, light golden yellow, coffee color, bronze color, gray, black, gray black, seven colors, etc. By controlling the relevant parameters in the process of coating, the color can be controlled; after coating, the color can be measured with relevant instruments, so that the color can be quantified to determine whether the color can meet the requirements.

The similarities and differences between PVD coating and traditional chemical plating (water plating) PVD coating and traditional chemical plating have the same points: both belong to the category of surface treatment, which make one material cover the surface of another material in a certain way. The differences between the two are: the adhesion between PVD coating and workpiece surface is greater, the hardness of the coating is higher, the wear resistance and corrosion resistance are better, and the performance of the coating is more stable; PVD coating will not produce toxic or polluting substances.

At present, PVD coating technology is mainly used in the industry. The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The purpose of decorative plating is mainly to improve the appearance, decoration performance and color of the workpiece and make the workpiece more wear-resistant and corrosion-resistant to extend its service life; in this respect, it is mainly used in various fields of hardware industry, such as door and window hardware, locks, bathroom hardware and other industries. The purpose of tool plating is mainly 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 cutting tools, turning tools (such as turning tools, planers, milling cutters, drills, etc.), various hardware tools (such as screwdrivers, pliers, etc.), various molds and other products. :

PVD decorative coating

The main characteristics and advantages of PVD (ion plating) technology - compared with vacuum evaporation coating and vacuum sputtering coating, PVD ion plating has the following advantages:

A. the binding force between the film layer and the workpiece surface is strong, more durable and wear-resistant

B. the ion diffraction performance is good, and the workpiece with complex shape can be plated with 0V + r0s4

C. fast film deposition rate and high production efficiency

D. wide range of coating types

E. the film has stable performance and high safety (it is FDA certified and can be implanted into human body)
