一、前言由于现代科学技术的发展,主要是:在设备上,向高压、高速、高温和高真空发展;在空间上,向外层空间和星球发展;在动力上,向原子能发展;而自古代起一直为人们所利用以解决润滑问题的油脂,已无法适应上速需要的各种在特殊条件下的润滑问题,促使人们的思想认识,从单纯的油脂润滑中解放出来。在现代润滑工程中,各种新型的固体润滑材料不断被发现和发明,甚至原来认为是锋利和坚硬的玻璃,在一定条件下,也可作为有效的高温润滑材料。但在目前应用得最多和最广泛的,当推胶体二硫化钼和胶体石墨二种。
I. INTRODUCTION Due to the development of modern science and technology, the main ones are: on equipment, developing towards high-pressure, high-speed, high-temperature and high-vacuum; developing in space to outer space and the planet; developing power to atomic energy; Since ancient times, people have been used to solve the problem of oil lubrication, has been unable to meet the need for a variety of upper speed lubrication under special conditions, prompting people’s thinking, from the simple grease lubrication liberation. In modern lubrication engineering, a variety of new solid lubricating materials continue to be discovered and invented, and even originally considered to be sharp and hard glass, under certain conditions, but also can be used as an effective high-temperature lubricating materials. However, at present, the most widely used and the most widely used, when the two kinds of push the body of molybdenum disulfide and colloidal graphite.
