The 863 nanometer material special project “Application and Industrialization of Nano-diamond Composite Coating†undertaken by Shanghai Jiaotong University passed the acceptance of experts. The project successfully developed nano-diamond composite coating technology and realized the industrialization of the product.
The nano-diamond composite coating not only has the characteristics of strong adhesion and wear resistance of the conventional diamond coating, but also has the advantages of smooth and smooth surface of the nano-diamond, small friction coefficient and easy grinding and polishing, and the nano-diamond composite coating drawing die is Carbide is a substrate, a conventional and nano-diamond composite coating is applied to the inner hole surface, and a new product obtained by grinding and polishing the coating is obtained. The nano-diamond composite coating drawing die developed by this project has been applied in more than 70 production enterprises such as Jiangsu Shangshang Cable Group Co., Ltd. and Shanghai Huapu Cable Co., Ltd., which has brought significant economic benefits to the application enterprises. The output value increased by 1.4 billion, the profit was 45.1 million yuan, the tax revenue was 60.09 million yuan, and the savings were 35.71 million yuan.
The subject uses chemical vapor deposition (CVD) to coat the surface of the hard alloy drawing die and other wear-resistant devices with a nano-diamond composite coating. The mature process for preparing the nano-diamond coating is obtained, and the nano-coating is completed. Layer structure and performance testing work, using nano-diamond composite coating technology to research and develop a variety of coating drawing molds and wear-resistant device products, solving key technical problems such as coating adhesion, uniform coating and coating surface finish. It has been widely used in drawing molds and wear-resistant devices for electric power, communication, building materials, mechanical processing and other industries, and has broad market application prospects.
