Abstract

The invention discloses a manufacturing method for a metal and ceramic gradient composite pipe, comprising the following steps: manufacturing a metal and inner ceramic gradient composite pipe by utilizing casting rolling technique, at first, obtaining casting slurry in accordance with volume percent of metal and ceramic at each layer of materials forming gradient ingredients, manufacturing the slurry into green compact layers by a casting process, then, as required by material ingredients of the composite pipe from an inner wall to an outer wall, wrapping the green compact layers in sequence on a roller shaft of a double-roller press for rolling formation so as to form a composite pipe biscuit, and sintering the composite pipe biscuit to obtain the metal and ceramic gradient composite pipe. The composite pipe manufactured according to the invention can control pipe diameter, wall thickness and gradient transition manner of pipe wall materials, and has simple manufacturing process and low production cost; the number of transition layers of the manufactured metal and ceramic gradient composite pipe is unlimited, has excellent abrasive resistance, chemical stability, a thermal impact resistance and great economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a preparation method of a composite material, in particular to a preparation method of a metal / ceramic gradient composite pipe. Background technique [0002] The U.S. patent "A Method for Preparing Ceramic-Lined Hollow Pipes Using Metal Thermal Reaction" (application number US-4363832, publication date 1982.12.14, publication number: 4363832) discloses a self-propagating method for preparing ceramic-lined metal pipes. High-temperature synthesis method (SHS), the ceramic-lined metal pipe prepared by this method is used in the transportation of molten aluminum. Although this method can carry out ceramic coating (including the coating with transition layer) on the inner surface of the metal pipe, there are still many problems to be solved in terms of the density, uniformity of the coating, and the design and control of the combustion process. Technical problems, especial...
