About 70% of the premature failure of various mechanical and electrical products is caused by wear and corrosion, and these two failure modes are closely related to the surface state of the material (physical, chemical and stress state, etc.). Therefore, the key to improve the performance of such materials is to improve their surface properties.
With the development of science and technology, the requirements for the surface properties of materials are getting higher and higher. In recent decades, with the rise of various vapor deposition technologies, the research and application of surface engineering technology has made rapid development. These technologies not only achieve the requirements of mechanical properties, such as wear resistance, anti-friction and anti-corrosion, but also in the field of electromagnetic, optical, optoelectronics, thermal, superconducting and biological and other functional materials related to the surface layer. Surface engineering not only makes low-cost metal materials play a greater advantage in terms of performance and efficiency, but also has become an important means of developing various new coatings and thin film materials, with great application potential.
With the improvement of the level of machining industry, new requirements are put forward for cutting tools. In addition to improving the service life, it is also required to reduce the pollution during cutting and use dry cutting as much as possible. When the cutting fluid cannot be completely eliminated, try to do it only contains rust inhibitors without organic matter, which can greatly reduce the cost of recycling.
The diversity of cutting tools and the characteristics of the working state during use determine the different coating of the tool. Turning and drilling are different, and milling cutters should consider the characteristics of their intermittent impact. Early development of the coating to wear as the main focus to improve the hardness of the main indicators. Such coatings, represented by titanium nitride, have a high coefficient of friction (0.4~0.6), and constant friction between the workpiece during processing will generate a large amount of heat energy. In order to avoid the tool overheating deformation affect the machining accuracy and prolong its service life, usually use cutting fluid.
