Abstract

The invention discloses 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.

Description

technical field

[0001] The invention relates to an indium-aluminum composite ball microcrystalline composite layer. Background technique

[0002] Friction and wear is one of the main reasons for the failure of machinery and automobiles. About 80% of the failure of mechanical parts is caused by various forms of wear, and the economic loss caused by the failure of mechanical parts reaches billions of yuan.

[0003] Therefore, it is of great application value and practical significance to study the microcrystalline composite layer of indium-aluminum composite balls.

[0004] According to the literature search and patent search results, there is no relevant patent literature report on the indium-aluminum composite ball microcrystalline composite layer in China. Contents of the invention

[0005] The task of the present invention is to provide a kind of indium-aluminum composite ball microcrystalline composite layer, and the task of the present invention is realized through th...
