Description

A kind of preparation method of wear-resisting stratiform particulate reinforced composite of heat-resistant anti-fatigue
 
Technical field
The invention belongs to the metal-base composites technical field, particularly a kind of preparation method of wear-resisting stratiform particulate reinforced composite of heat-resistant anti-fatigue.
Background technology
Development of modern industry requires increasingly high to the anti-wear performance of material; Departments such as metallurgy, mine, building materials, electric power, chemical industry, coal and agricultural will use mining machinery, engineering machinery, agricultural machinery and various crushing and grinding machinery respectively; The consumable accessory of these plant equipment will receive the wearing and tearing of various materials such as sandstone, ore, soil and abrasive body, and will consume a large amount of metals every year.According to incomplete statistics, 1/3~1/2 of the energy consumes relevant with friction and wear.Concerning material, about 80% part failure is caused by wearing and tearing, wherein accounts for 50% because of what abrasive wear was lost efficacy, and China is used for the wear-resisting iron ironware of abrasive wear operating mode according to statistics, will consume more than 200 ten thousand tons every year.Thus, develop out a kind of can be under wear working condition, the new material that has than the long life seems very important.
There is bad working environment in many fields in industry, and the work parts of requirement possess antiwear heat resisting or wear-and corrosion-resistant combination property simultaneously, and the material that therefore has single performance can not satisfy the demand of operating mode.Composite organically combines them through physics or chemical method owing to be with two kinds or above material with different qualities, display one's respective advantages, so material has the excellent comprehensive performance.In recent years, a large amount of work had been done in the research of composite material preparation process, developed kinds of processes.When these processes were used to make the non-ferrous metal composite, because the most of fusing points of non-ferrous metal are low, and wellability was good between a lot of enhanced granule, had therefore obtained good effect.Strengthen Al alloy composite like SiC and make piston, increase substantially service life.Yet as far as ferrous metal, because fusing point is high, metallurgical reaction is complicated each other, and enhanced granule is added in the ferrous metal liquid, is a difficult problem always, and this has a strong impact on the industrialization process that particle strengthens the iron iron base composite material.For many years, the technical study that particle is strengthened the iron iron base composite material is one of key subjects of composite research always, has also obtained some achievements.Patent (publication number 1080221) has been introduced a kind of casting method that particle strengthens wearing composite material for preparing; Its processing step is: carry out casting mold earlier; Preparation size is the disappearance mould of minus deviation simultaneously, again the disappearance mould is put into casting mold, between disappearance mould and casting mold, just forms the space like this.Hard particles is filled up in the space, and mould assembling vacuumizes cast, thereby forms the high-abrasive material that contains hard particles on the surface.This method complex procedures can not be well uses the advantage of disappearance mould negative pressure casting technology, and production efficiency is low, and composite bed thickness and difficult quality guarantee.CN1383945A discloses a kind of preparation method of particulate reinforced composite, and its process is: carry out foam mould earlier, need make the position of composite at foundry goods; With molded two parts bonding that makes; One of them is shaped on groove, will mix the enhanced granule that makes then and fill up groove, and the two parts with mould bond again; Coat the oven dry moulding, vacuumize cast at last.This method preparation is complicated, is not suitable for demand of practical production.CN101053898A has introduced a kind of vacuum full mold cast-infiltration method for preparing particulate reinforced metal-based composite surface material; This method is that enhanced granule is prepared into the prefabricated section that adapts with the required wearing face shape of composite; Being fixed in needs the foamed material of alloying apperance surface, then by casting technique moulding and cast.CN1128297A has announced a kind of local composite material and manufacturing approach thereof; It is with ceramic particle, organic binder bond and common carbon steel group, heat-resisting base steel or nickel base powder mixing; Be pressed into the prefabricated section of required form, place the casting mold of the foundry goods that needs reinforcement local, casting metal gets final product.Above-mentioned two kinds of inventions and the present invention are similar, and wherein maximum difference is not heat-resistant anti-fatigue of composite that above-mentioned two kinds of methods make, chilling and shock heating for several times after, the mortality crackle can appear in its composite bed, thereby reduces its service life; CN101422814A discloses a kind of preparation method of local composite abrasion resistance material, and it is to select high alloy powder core pipe silk for use, according to the shape of surface of the work, cutting, rolls or superposes and process analog structure; According to the casting technique moulding, the high alloy powder core pipe silk of making is embedded in the sand mold die cavity, smelt the cast of substrate metal material, thereby obtain required composite.The shortcoming of this method is to be prone to form dreg defect, and process controllability is relatively poor when being used for actual production, is not suitable for large-scale industrial production.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of preparation method of wear-resisting stratiform particulate reinforced composite of heat-resistant anti-fatigue is provided, preparation can be satisfied the high-performance composite materials that use under the complex working conditions such as various wearing and tearing, chilling and shock heating.
The present invention realizes through following technical proposal: a kind of preparation method of wear-resisting stratiform particulate reinforced composite of heat-resistant anti-fatigue, and following each step of process:
