Abstract

The invention discloses a method for modifying a high-wettability coating on the surface of a metal-based compound material reinforcement. The method comprises the following steps of: 1, by a common coating preparation method, forming a metal oxide coating, of which reducibility is lower than that of magnesium, on the surface of the reinforcement; 2, and placing the reinforcement coated with the metal oxide coating and pure magnesium in a vacuum furnace in a way of placing the pure magnesium on the bottom of the furnace and placing the reinforcement above the pure magnesium, vacuum-pumping the furnace, keeping the vacuum degree below 10Pa, heating the furnace to 600 to700 DEG C, and keeping the temperature for 5 to 60 minutes so as to allow the magnesium steam and the metal oxide coating on the surface of the reinforcement to undergo an oxidation-reduction reaction to generate a compound layer formed by an inner layer made of compounds and an outer layer made of reduced metal. The method has the advantages of simple and controllable process, low equipment requirements, low cost, wide application range, high mechanical and physical properties and the like.

Description

1. Technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for modifying a high-wettability coating on the surface of a metal-matrix composite material reinforcement. 2. Background technology [0002] Materials are the material basis and forerunner of social progress. Higher, stricter and more requirements are put forward for the performance of materials. In many respects, traditional single materials are increasingly unable to meet actual needs. A composite material is a multiphase solid material composed of two or more substances with different physical and chemical properties. Composite materials can be designed, that is, through the selection of raw materials, the distribution of various components and the guarantee of process conditions, etc., the advantages of the original component materials can be complemented, thus showing excellent comprehensive performance. Among them, metal matrix compos...
