Abstract
A method for manufacturing composite bucket teeth by an anti-friction metal and ceramic hybrid surface layer is characterized by comprising the steps of coating an anti-friction material composite layer in an abrasive mode, preparing the anti-friction material composite layer and conducting pouring. The anti-friction material composite layer is composed of, by weight, 23-26% of Cr, 19.8-20.2% of WC, 4.95-5.05% of TiC, 1.2-1.5% of Cu, 1.0-1.5% of Mo, 0.5-0.9% of Mn, 0.5-0.8% of Si, 3.0-5.0% of B2O3 and the balance Fe. According to the pouring step, high-temperature base body liquid metal is in effective contact with anti-friction materials arranged on an evanescent mold in a coating mode through the gasification evanescent mold. The method for manufacturing the composite bucket teeth by the anti-friction metal and ceramic hybrid surface layer has the advantages that the strength, the anti-friction performance and the impact resistance of the bucket teeth are improved, and therefore the service life of the bucket teeth is prolonged.
Description
Technical field
The present invention relates to antifriction metal (AFM) mixes top layer and manufactures the method for compound shovel and the high-abrasive material of employing with pottery.
Background technology
The manipulating object of forklift, excavator is silt, the cubic metre of earth and stone, and environment for use is severe, and teeth need to bear harsh material friction and impact and rapid wear requires wear-resisting and high strength to teeth, and shock-resistant.The teeth of existing industrialization mainly contains the materials such as low-carbon alloy steel, medium carbon alloy steel, potassium steel, and the production method of teeth is casting substantially.Because adopting overall a kind of material, traditional mode of production makes, when not having condition to accomplish to require a kind of material to there is high strength and high impact flexibility, there is again high hardness, therefore, traditional production method can only be using shock-resistant teeth and not brittle failure as primary satisfied requirement, and hardness can not require too high.
Summary of the invention
Object of the present invention is just to provide a kind of material of high strength, high tenacity that adopts as matrix, place easy to wear, top layer complex abrasion-proof metal and ceramic composite material, both ensured that teeth had high intensity and toughness and makes teeth surface have high hardness and the employing antifriction metal (AFM) that improves wearability and pottery mix top layer and manufacture the method for compound teeth.
The solution of invention is such:
Adopt antifriction metal (AFM) to manufacture the method for compound shovel and comprise step with the ceramic top layer of mixing:
(1), manufacture teeth casting mold step: pre-buried evaporative pattern in teeth casting mold;
(2), snearing high-abrasive material composite bed step: use anhydrous bonding agent, by high-abrasive material composite bed snearing on evaporative pattern;
(4), high-abrasive material composite bed preparation steps: mainly by the following raw material preparation high-abrasive material composite bed that contains precentagewise formula:
(5), cast step: teeth matrix adopting ZG30CrMnSi high-strength alloy material forms high temperature metal liquid by melting, in casting process, by vacuumizing, make casting mold die cavity be greater than 0.4Mp state in negative pressure, high temperature matrix liquid metal effectively contacts with the high-abrasive material being sticked and coated on evaporative pattern by gasification evaporative pattern, the metal liquid of high temperature and composite fusion and sintering.
Advantage of the present invention is that teeth adopts high-intensity material to do matrix, top layer complex abrasion-proof metal and ceramic composite material, the advantage of the advantage of high-strength material and high-abrasive material is combined by casting technique, fully play the advantage of metal and the ceramic material of high-strength alloy material and high abrasion, intensity, wearability and the impact resistance of teeth are improved greatly, thereby be 3～10 times of conventional teeth the service life of raising teeth.
