Abstract

The invention discloses a high-temperature bionic self-lubricating hot work die material which comprises a matrix skeleton and a sold lubricating material; the matrix skeleton is a metal skeleton which is prepared by alloy powder through a rapid formation technology and has a microporous structure with regular distribution; micropores in the metal skeleton are connected with and penetrated through one another; and the sold lubricating material is stored in the micropores in the metal skeleton to precipitate out during die work to achieve the lubrication antifriction effect. By adopting the high-temperature bionic self-lubricating hot work die material provided by the invention, the problems that the infiltration performance between a lubricant and a matrix is poor, the interface bonding strength between the lubricant and the matrix is low, a solid lubricant is insufficient in burning loss in the sintering process, and shapes and distribution of matrix cell holes are difficultly controlled to cause defects of connection performance of the micropores and randomness of material strength are solved.

Description

technical field [0001] The invention relates to the technical field of hot working die materials, in particular to a high-temperature bionic self-lubricating hot working die material and a preparation method thereof. Background technique [0002] During the service process of the mold, due to the deformation and flow of the metal to be formed, intense friction occurs on the surface of the mold, which causes the surface material of the mold to wear, and the machining shape and roughness of the mold change, resulting in the shape, size and surface quality of the processed parts. If the requirements are not met, the mold will fail at this time. Lubrication is the most effective measure to reduce friction and reduce die wear. [0003] Especially when the hot work mold is in contact with the hot metal when it is working, it will cause the surface metal of the cavity to be heated, and the metal on the surface of the cavity will cause thermal wear and thermal fatigue (cracking). ...
