一、概述随着尖端科学技术的不断发展,现代化工业水平的不断提高,对于各种机器设备、机械构件和机械摩擦副零部件等提出了高转速、高效率和长寿命等方面的要求。为此,上述工作表面就必须具有耐磨损、耐腐蚀、耐高温和抗氧化等表面特殊性能。热喷涂技术作为表面保护、表面强化和修复旧件等方面的新技术,是获得上述表面特殊性能的有效方法之一。由于该技术具有工艺简便、技术可
I. Overview With the continuous development of cutting-edge science and technology, the continuous improvement of the modern industrial level, for a variety of machinery and equipment, mechanical components and mechanical friction pair of parts put forward the requirements of high speed, high efficiency and long life. To this end, the above-mentioned working surface must have wear-resistant, corrosion-resistant, high temperature and oxidation resistance and other special surface properties. Thermal spraying technology as a surface protection, surface hardening and repair of old pieces of new technologies, is one of the effective ways to obtain the above-mentioned special surface properties. Due to the technology is simple and technically feasible
