Application prospect of laser surface strengthening and remanufacturing technology

Laser surface strengthening and re manufacturing and processing technology of modern industrial development has important fill gaps and improve the technology level of the role, can repair the wear parts processing and surface modification, used in the manufacture of new parts and manufacture to improve the hardness, wear resistance, corrosion resistance and fatigue resistance, high temperature resistance surface and improve the service life of materials, the laser remanufacturing is manufacturing and repair, recovery and utilization, the organic combination of production and circulation. Auto parts remanufacturing products are mainly used for maintenance, not only can improve the quality of maintenance technology, but also can improve the efficiency and efficiency of maintenance. Foreign experience shows that, when re manufacturing parts accounted for 65% of the repair parts market, the speed of vehicle maintenance will increase by 8 times. The development of manufacturing industries also make manufacturing enterprises have the ability to put more efforts on new product development and design, forming a virtuous circle, to update the adjustment of industrial structure, promote the products of China's manufacturing industry upgrading and technological progress and improving the quality of personnel is very favorable.

China's iron and steel, metallurgical equipment, automobiles, construction machinery, machine tools and other social rapid growth in quantity, re manufacturing industry has great potential for development. China's crude steel output reached 822 million 697 thousand and 800 tons in 2014, the civilian vehicle population reached 264 million, of which 154 million cars, the number of cars only in the United States ranked second in the world, accounting for 15% of the total world, machine ownership more than 8 million units, engineering machinery products reserves amounted to 611-662 million. Where a lot of equipment in reaching the wear cycle or scrap requirements will be repaired or eliminated, newly retired equipment is still a substantial increase, these industrial conditions for laser surface strengthening and manufacturing industries to form a new economic growth point, and offers a number of employment opportunities for the society.

To speed up the development of laser surface strengthening and remanufacturing industry is an effective way to promote the development of manufacturing and modern service industry, the current size of the domestic enterprises in the use of laser surface hardening and tens of thousands of manufacturing processing equipment and technology, and in recent years, along with the power of laser cladding and a large number of devices on the introduction of the needs of various industries technology is increasing rapidly, in addition, with the continuous progress of the modern science and technology, the performance of all the equipment and devices will be further improved, the material requirements are increasingly high, vigorously support the national development and Reform Commission, the Ministry of resource recycling and green manufacturing applications, further improvement and development of laser surface processing technology will be usher in a new face.
