PVD(物理气相沉积)技术在二十世纪七十年代末，开始应用在提高机械力学性能的硬质膜方面，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。比较初在高速钢刀具优先域的成功应用引起了世界各国工具制造业的高度重视，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。PVD工艺对环境无不利影响，符合现代绿色制造的发展方向。

PVD (Physical Vapor Deposition) technology has been applied to improve mechanical properties of hard films in the late 1970s. The prepared films have the advantages of high hardness, low friction coefficient, good wear resistance and chemical stability. At first, the successful application of high-speed steel tools has attracted great attention of tool manufacturing industry all over the world. While developing high-performance and high-reliability coating equipment, more in-depth coating application research has been carried out in cemented carbide and ceramic tools. PVD process has no adverse impact on the environment, which is in line with the development direction of modern green manufacturing.

镀钛工艺处理温度可控制在150～500℃以下，因此镀钛工艺可用于多种材质基体的涂层，不仅具有多姿多彩的装饰效果，更重要的是采用PVD技术可使涂层具有优异的理化特性，大幅度强化基体表面诸如硬度、摩擦系数等物理特性指标。

真空离子镀钛应用的就是PVD技术。

The application of vacuum ion plating titanium is PVD technology.

金属在特定环境下(压力，温度，电磁场等)与各种气体(氩气，氮气，氧气及乙炔气等)产生综合作用形成等离子体，经过加速后，等离子体涌向被镀工件表面，形成牢固的膜层。该镀钛膜层细密均匀，结合力强，硬度高，防腐耐磨，具有良好的导电性和自润滑性能，同时色泽丰富多样，因此真空镀钛不仅是提高材料使用性能的有力手段，在装饰上同样是提升档次，提高附加值的比较佳选择。

Metals react with various gases (argon, nitrogen, oxygen, acetylene, etc.) to form plasma in a specific environment (pressure, temperature, electromagnetic field, etc.). After acceleration, plasma rushes to the surface of the plated workpiece to form a solid film. The titanium coating is fine and uniform, with strong adhesion, high hardness, anti-corrosion and wear resistance. It has good conductivity and self-lubricating properties. At the same time, it has rich and diverse colors. Therefore, vacuum titanium plating is not only a powerful means to improve the performance of materials, but also the best choice to upgrade the grade and increase the added value in decoration.

刀具涂层技术是指在强度和韧性较好的硬质合金或高速钢（HSS）基体表面上，利用气相沉积方法涂覆一薄层耐磨性好的难熔金属或非金属化合物，刀具涂层作为一个化学屏障和热屏障，减少了刀具与工件间的摩擦、扩散和化学反应，从而减少了月牙洼磨损。刀具涂层具有表面硬度高、化学性能稳定、耐热耐氧化、耐磨性好、摩擦因数小和热导率低等特性。昆山天恩镀钛厂所做的涂层刀具与未涂层刀具的切削状况，未涂层刀具，因摩擦系数大等原因存在严重的积屑瘤，涂层后的刀具，摩擦系数小，无明显积屑瘤。

Tool coating technology refers to coating a thin layer of refractory metals or non-metallic compounds with good wear resistance on the surface of cemented carbide or high speed steel (HSS) with good strength and toughness by vapor deposition. Tool coating acts as a chemical and thermal barrier, which reduces friction, diffusion and chemistry between tool and workpiece. The reaction reduces the wear of crescent depression. Tool coating has the characteristics of high surface hardness, stable chemical performance, heat resistance, oxidation resistance, good wear resistance, small friction coefficient and low thermal conductivity. Cutting condition of coated and uncoated cutting tools made by Kunshan Tianen Titanium Plating Plant, as well as uncoated cutting tools, there are serious debris tumors due to large friction coefficient. The coated cutting tools have small friction coefficient and no obvious debris tumors.
