Abstract

The invention discloses an iron-based ceramic composite material and a preparation method and application thereof, and belongs to the technical field of metal materials. The iron-based ceramic composite material comprises the following components in percentage by weight: less than or equal to 0.05% of C, 10.00%-25.00% of Cr, 7.00%-12.00% of Ni, 0.50%-3.00% of Mo, 0.80%-3.20% of Al, less than or equal to 0.60% of Mn, less than or equal to 1.00% of Si, 5.00%-15.00% of TiC, and the balance of Fe. The iron-based ceramic composite material prepared from the components has good strength, hardness and wear resistance, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to an iron-based ceramic composite material and a preparation method and application thereof. Background technique [0002] Lightweight, high-strength, multi-functional advanced metal matrix composites with excellent mechanical properties can meet the needs of structural lightweight and structural-functional integrated design, and are irreplaceable keys to the development of high-tech fields such as aerospace, auto parts, electrical electronics, and national defense. base material. In order to reduce the overall weight of structural parts and further improve the comprehensive mechanical properties of materials, it is often necessary to carry out research and development and trial production of lightweight steel. A time-consuming and labor-intensive process requiring complex post-heat treatment is only possible to achieve the target properties. In order to bette...
