Abstract

The invention discloses a surface texture of an indium-aluminium composite spherical microcrystal composite layer. A surface material layer is arranged on a part, a metallographic structure of the surface material layer comprises larger indium-aluminium composite spherical microcrystals of which the indium content exceeds 50% (Wt%) and the total content of indium and aluminium exceeds 55% (Wt%), each larger indium-aluminium composite spherical microcrystal is formed by close connection of at least four spherical or nearly-spherical crystal grains with sizes smaller than 300 nm, and the indium-aluminium composite spherical microcrystals account for more than 50% of total crystals constituting the surface material layer; a base body material can adopt metallographic structures which are made of other components and are in other shapes, and the surface material layer and the base body material of the part are integrated to form the indium-aluminium composite spherical microcrystal composite layer; a surface texture is machined on the part surface provided with the indium-aluminium composite spherical microcrystal composite layer and consists of multiple surface texture units, and the surface texture of the indium-aluminium composite spherical microcrystal composite layer is formed.

Description

technical field [0001] The invention relates to the surface texture of an indium-aluminum composite ball microcrystalline composite layer. Background technique [0002] Friction and wear are one of the main reasons for the failure of products such as machinery and automobiles. About 80% of the failures of mechanical parts are caused by various forms of wear and tear, and the economic losses caused by the failure of mechanical parts reach billions of yuan. [0003] Surface texture refers to the processing of micro-texture patterns such as pits and dents with a certain size and arrangement on the surface of the friction pairs that are connected and contacted with mechanical parts by a certain processing technology. After years of hard work by domestic scientists and engineers, surface texture technology has made significant progress, however, it has not been widely used in practice. [0004] Therefore, it is of great application value and practical significance to study the s...
