Embodiment 1

[0022] Example 1, figure 1 , figure 2 It is a simplified structural diagram of the blow bar. Both sides A and B are used surfaces, which require high wear resistance. They are made of WC and high-chromium cast iron composite wear-resistant materials. The particle size of WC is 50-100 mesh, and the grade of high-chromium cast iron is KmTBCr15. This embodiment is the preparation method of the above-mentioned composite wear-resistant material, with reference to image 3 , Figure 4 :according to image 3 The foam plastic mold 1 is prepared as shown, and the groove 2 on the body is filled with dry and clean WC reinforcing particles into the groove of the foam plastic mold; after the foam plastic mold is bonded, paint, dry, shape, and vacuumize; The molten iron of high chromium cast iron with qualified composition is poured into the mold. The pouring temperature is 1400°C, and after cooling, the box is opened to obtain composite wear-resistant material castings with WC particl...

Abstract

The particle-reinforced composite material casting process is used in preparing wear-resisting and heat resisting, wear-resistant and anticorrosive and other composite material. The process includes:fabricating formed plastic mold with channel in the part corresponding to the composite material part of casting; filling the channel with reinforcing particle stuffing before adhering different moldpart; painting, stoving and molding; and vacuum casting. Through the disappeared mold and negative casting process, casting with composite material may be prepared easily. The present invention has the advantages of clear reinforcing particle leading to no inclusion and air void defect, optional composite location and homogeneous particle distribution.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to a method for preparing composite materials by adopting a particle-reinforced process, and is particularly suitable for manufacturing composite materials with comprehensive properties such as wear resistance, heat resistance, and corrosion resistance. Background technique [0002] There are harsh working environments in many fields of industry, requiring working parts to have comprehensive properties of wear and heat resistance or wear and corrosion resistance at the same time, so materials with a single performance can no longer meet the needs of working conditions. Composite materials have excellent comprehensive properties because they combine two or more materials with different characteristics through physical or chemical methods to give full play to their respective advantages. In recent years, a lot of work has been done on the research on the preparation process of composite m...
