提到不锈钢这种耐腐蚀能力强的金属材料，人们总是会想到它银白色、镜面的效果。实际上，除了本身不锈钢外，各种工艺处理的彩色不锈钢也早已走入日常生活，这些色彩甚至完全超越了我们的想象力。建筑中，彩色不锈钢的应用在室内装饰最为常见，如电梯轿厢、门框、装饰墙面。

When it comes to stainless steel, a corrosion-resistant metal material, people always think of its silvery-white, mirror effect.In fact, in addition to its own stainless steel, a variety of processed colored stainless steel has already entered the daily life, these colors are even completely beyond our imagination.In buildings, the application of color stainless steel is the most common in interior decoration, such as elevator car, door frame and decorative wall.

不锈钢本身呈银灰色，可以通过表面树脂涂层（类似于涂层钢板）、化学及电化学着色、PVD真空镀膜等技术可以形成各种色彩的彩色不锈钢。表面树脂涂层相当于在金属表面涂饰了一层漆面，掩藏了金属的质感，同时耐候性也不比不锈钢本身，因此这种工艺现在已基本被淘汰。现在实际应用的以PVD真空镀膜及各种氧化镀膜为主。

The stainless steel itself is silver gray and can form a variety of color stainless steel by surface resin coating (similar to coated steel plate), chemical and electrochemical coloring, PVD vacuum coating and other technologies.Surface resin coating is equivalent to a layer of paint on the metal surface, covering the texture of the metal, and the weather resistance is not less than the stainless steel itself, so this process is now basically eliminated.Now the actual application of PVD vacuum coatings and various oxidation coatings.

PVD真空镀膜技术（Physical Vapor Deposition，物理气相沉积）即是在真空条件下采用物理方法，将某种材料气化成原子、分子或部分电离成离子并经多种反应后，进而使其在基板表面沉积为一层功能性的薄膜。

PVD vacuum coating technology (Physical Vapor Deposition, physical vapor deposition) is a physical method into atoms, molecules or partially ionized into ions after multiple reactions, and then deposits it as a functional film on the substrate surface.

使用PVD技术可获得的颜色（涂层成分）主要有：金（TiN）、玫瑰金（ZrN）、青铜（TiAlN）、蓝色（TiAlN）、黑色（TiAlCN）、酒红色（ZrN）。这些涂层非常薄，完全可以显示底层基板的质感。

The colors (coating ingredients) available using PVD technology are mainly gold (TiN), rose gold (ZrN), bronze (TiAlN), blue (TiAlN), black (TiAlCN), Burgundy (ZrN).These coatings are very thin and can fully show the texture of the underlying substrate.

在国内常见的PVD真空镀膜不锈钢以“金色系”较多。

The most common domestic PVD vacuum coated stainless steel to "gold series" more.

彩色不锈钢不仅具有多样性的色彩，一般还因为表面涂层的作用在一定程度上增强了不锈钢的耐腐蚀性能及耐磨性能。

Color stainless steel not only has a variety of colors, but also generally because of the role of the surface coating to enhance the corrosion resistance performance and wear resistance performance of stainless steel to a certain extent.
