Embodiment Construction

[0009] A method for preparing a steel-based surface layer composite material, the specific steps of which are as follows:

[0010] The first step, the preparation of the prefabricated layer: use a ball mill to mix the reinforcing particles and alloy powder pre-added into the prefabricated layer evenly, then add an appropriate amount of binder (6wt% PVA aqueous solution) and continue stirring until a paste-like prefabricated layer is obtained. The prefabricated layer is composed of WC particles, high-carbon ferrochrome powder and binder, and WC reinforcing particles are mixed with high-carbon ferrochrome powder according to different volume fractions;

[0011] The second step is the preparation of the foam pattern and the presetting of the prefabricated block: the size of the foam pattern is 40×40×40mm, and the paste prefabricated block is directly coated on the 40×40mm surface with a thickness of 3mm;

[0012] The third step is the bonding and painting of the pouring system: d...

Abstract

The invention relates to a preparation method of a steel base surface composite. The WC/high chrome steel base surface composite is prepared by vacuum-evaporative pattern casting (V-EPC).

Description

technical field [0001] The invention relates to a method for preparing a composite material, in particular a method for preparing a steel-based surface layer composite material. Background technique [0002] The method of preparing steel-based surface composite materials in traditional technology is very cumbersome and costly. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a method for preparing steel-based surface layer composite materials. [0004] In order to achieve the above object, a method for preparing a steel-based surface layer composite material of the present invention, the specific steps are as follows: [0005] The first step, the preparation of the prefabricated layer: use a ball mill to mix the reinforcing particles and alloy powder pre-added into the prefabricated layer evenly, then add an appropriate amount of binder (6wt% PVA aqueous solution) and continue stirring until a paste...
