Metal-matrix composite ceramic liner plate and preparation method thereof

Abstract

The invention discloses a metal-matrix composite ceramic liner plate. Zirconia aluminum oxide, high chromium iron powder and iron powder are electrically smelted and injected into a metal-matrix ceramic reinforcement with a plurality of communicated plug holes to form the metal-matrix composite ceramic liner plate; the upper and lower end faces of the metal-matrix ceramic reinforcement are provided with communicated plug holes, and four side faces of the metal-matrix ceramic reinforcement are provided with communicated grooves; after different reinforcements are spliced, grooves on edges of two adjacent reinforcements form complete plug holes, a metal liquid is poured into the plug holes and can infiltrate among ceramic particles of the reinforcements through the plug holes and uniformly coat the ceramic particles, so that a ceramic phase and a metal phase are uniformly distributed. Therefore, the toughness and wear resistance of the finished ceramic products are enhanced, and the thermal shock resistance of the finished ceramic products is improved.

Description

technical field

[0001] The invention relates to a wear-resistant ceramic liner, in particular to a metal matrix composite ceramic liner and a preparation method thereof. Background technique

[0002] Wear-resistant ceramic sheets have many aliases due to different regions and habits, such as ceramic sheets, linings, ceramic mosaics, alumina linings, high-alumina linings, etc. It is a material mainly composed of alumina, supplemented by other rare materials. Metal oxides are solvents, which are sintered at a high temperature of 1700 ° C. They are widely used in coal transportation, material transportation systems, pulverizing systems, exhaust systems, etc. Ash, dust removal system and other mechanical equipment with heavy wear.

[0003] The wear-resistant ceramic sheets in the prior art are mainly composed of cermet materials with aluminum oxide as the ceramic phase, which have the basic properties of ceramics, that is, high hardness and high temperature resistance, so the w...
