Abstract

The invention discloses a concave indium-magnesium microcrystalline composite layer. The concave indium-magnesium microcrystalline composite layer is characterized in that a surface material layer is arranged on a part, wherein a metallographic structure of the surface material layer comprises concave-groove-shaped or concave-through-hole-shaped microcrystallines; the microcrystalline is characterized in that the content of indium in the microcrystalline is greater than 50wt% and the total content of indium and magnesium in the microcrystalline is greater than 55wt%; the number of concave-groove-shaped or concave-through-hole-shaped microcrystallines is greater than 15% of the total number of the crystals formed by the surface material layer; a base material can be formed by other components and other-shaped metallographic structures; the surface material layer and the base material of the part are integrated to form the concave indium-magnesium microcrystalline composite layer.

Description

technical field [0001] The invention relates to 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] As we all know, the performance of the surface material layer of parts will be significantly different due to different microstructures. The microstructures of materials containing indium with the same composition have spherical, octahedral and other shapes, resulting in different comprehensive properties. According to the results of literature search and patent search, there is currently no relevant patent literature report on the indium magnesium concave microcrystalline composite layer in China. Therefore, the study of indium magnesium concave microcrystalline composi...
