Abstract

The invention belongs to the technical field of solid lubricating materials, and particularly relates to titanium monosulfide particles, a composite material of the titanium monosulfide particles, preparation and application of the titanium monosulfide particles and a coating material. The titanium monosulfide particles are of a layered structure formed by stacking two-dimensional nanosheets. The invention discloses a novel TiS particle, and experimental results prove that the titanium monosulfide used as a high-temperature-resistant coating has the following unexpected excellent properties: the friction coefficient is in a decreasing trend along with the increase of the temperature (which is obviously different from the trend of the traditional material, the increase of the temperature and the decrease of the friction coefficient); and the lowest friction coefficient of 0.08 is realized at the temperature of 1000 DEG C. The invention further discloses the ZrO2 (at) TiS composite material. Compared with pure titanium monosulfide, the lubricating property of the ZrO2-coated TiS composite material coating is relatively reduced, but the reduction of the preparation cost provides guarantee for the effects of the ZrO2-coated TiS nano composite material in different fields.

Description

technical field [0001] The invention belongs to the technical field of solid lubricating materials, and specifically relates to titanium sulfide particles, its composite material, its preparation, application and coating material. Background technique [0002] Friction is closely related to our life, but unnecessary friction and wear become the resistance to the development of green economy and the construction of ecological civilization. According to statistics, about one-third of the primary energy in the world is consumed by friction and wear every year. At the same time, the wear between friction pairs will cause about 80% of the parts and mechanical equipment to fail, and the vicious accidents of mechanical equipment caused by lubrication or excessive wear can reach as high as more than 50%. In addition, most industrially developed countries in the world account for 5%-7% of the national gross national product due to friction and wear related energy consumption, materi...
