Abstract

The invention discloses a surface texture of an indium-magnesium inwards-concave microcrystal composite layer. The surface texture of the indium-magnesium inwards-concave microcrystal composite layer is characterized in that a surface material layer is arranged on a part, a metallographic structure of the surface material layer comprises inwards-concave groove-shaped or inwards-concave through-hole-shaped microcrystals of which the indium content exceeds 50% (Wt%) and the total content of indium and magnesium exceeds 55% (Wt%), and the inwards-concave groove-shaped or inwards-concave through-hole-shaped microcrystals account for more than 15% 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-magnesium inwards-concave microcrystal composite layer; a surface texture is machined on the part surface provided with the indium-magnesium inwards-concave microcrystal composite layer and consists of multiple surface texture units, and the surface texture of the indium-magnesium inwards-concave microcrystal composite layer is formed.

Description

technical field [0001] The invention relates to the surface texture of an indium-magnesium concave 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] Surface texture refers to the micro-texture pattern matrix of pits, dents and other micro-texture patterns with a certain size and arrangement processed by certain processing technology on the surface of the friction pair of interconnected contacting mechanical parts. After many years of hard work by many domestic scientific and technological workers and engineers, the surface texture technology has made significant progress, however, it has not yet been widely used in practice. Therefore, it is of great application value and practical significance...
