China Heat Treatment and Surface Modification Technology Roadmap (I)
Time：
May 23,2016
Heat treatment and surface modification to give advanced materials limit performance and key components limit service performance, belongs to the national core technology, it has a pivotal role in the process of China from a large materials and machinery manufacturing power to a strong country. Therefore, it is of strategic importance to raise awareness and devote national efforts to prioritize the development of heat treatment and surface modification technology to change the backward situation.
Surface modification efficacy are: ① inhibit the fatigue strength of key components stress concentration sensitive. Once the surface modification technology is used, the fatigue strength of the key components will have nothing to do with the concentration of stress and return to the level of the inherent fatigue strength of the material. ②Table hardening improves the fatigue life of transmission critical components. ③Improve the fatigue life of rotating key components. ④Improve the fatigue life of high temperature rotating key components. ⑤Solve the problem of major service failure of key components. ⑥The fatigue life of aircraft landing gear reaches the advanced level abroad. (7) The surface modification triggered a new concept of machinery manufacturing. From the current "forming" manufacturing of key components, the surface integrity manufacturing of developed countries has been leapfrogged to fatigue-resistant manufacturing.
China Heat Treatment and Surface Modification Technology Roadmap" to create a "precision - efficient - economic - clean - industry" heat treatment and surface modification industry with Chinese characteristics: 1) to establish a surface hardening technology system and industry, 2) to establish a traditional, high-energy, high-energy composite surface modification technology system and industry, to reach the international advanced level, 3) Establish vacuum heat treatment technology system and industry to create a precise and clean environment to meet the needs of various key components and components, 4) Focus on extra-large and shaft key components and establish induction heat treatment technology system and industry with Chinese characteristics, 5) Focus on special parts and special performance requirements of key components, independently innovate and establish laser beam, electron beam and solar beam surface heat treatment technology system and industry, 6) Establishing precision heat treatment technology system, 7) Independent innovation and establishment of heat treatment industry for extra-large key components with Chinese characteristics, 8) Independent innovation and establishment of virtual heat treatment technology system and industry with extra-large key components as the entry point, 9) Independent innovation of quenching and cooling medium and establishment of technology system to rapidly form a non-polluting quenching and cooling medium industry for key components with Chinese characteristics, 10) Independent innovation of heat treatment and surface modification sensor and its technical system, the rapid formation of industry, 11) the establishment of heat treatment and surface modification equipment technology system and industry, 12) the establishment of heat treatment and surface modification engineering technology system and scale industry.
China can only seize this opportunity, "precision - efficient - economic - clean - industrial" "Roadmap" will bring China's heat treatment, surface modification technology and key components into an international advanced level, the development of competition.
