点铁成金——纳米让金属更耐磨

Turn Iron into Gold by Touching—To Improve the Wear Resistance of Metallic Materials by Nano-Modification

摘要: 纳米材料能够赋予产品以奇特而优异的性能。但因目前科技发展水平和生产成本的制约，完全以纳米材料替代常用的传统材料还不现实。为满足新型金属耐磨材料的发展和应用需求，简便可行且成本低廉的金属耐磨材料纳米改性技术就显示出了独特优势和重要性。本文简要介绍了最近十几年来我们课题组在金属耐磨材料纳米改性研究与应用方面的有关进展，试图说明材料纳米改性科学技术的支撑作用和利用材料纳米改性科学技术优势进行产品创新的重要性，采用纳米改性技术可以在纳米尺度上控制材料的局部、表面或整体，使材料的性能潜力得到更有效地发挥，可以显著提高装备制造业产品或零部件的使用性能、寿命和可靠性。

Abstract: Nano-materials can endow the products with unique and excellent properties. However, to replace com-pletely the traditional materials with nano-materials is not reality due to the current level of science and technology de-velopment and the control of production cost. To meet the requirements of development and application of wear-resis-tant metallic materials, simple and inexpensive nano-modification technology shows the unique advantage and impor-tance. This paper briefly introduces the research and application progress of our group in the wear-resistant materials nano-modified in recent ten years, trying to illustrate the supporting role and importance of nano-modification science and technology of materials, and the advantages of nano-modification of materials during product innovation. Using the nano-modification technology can control of the surface, or local, or overall of materials in nanometer scale to more effectively play the performance potential of materials, can significantly improve the performance, life and reliability of products or parts in equipment manufacturing industry.
