Abstract
The method that the mold air retaining wall produces foundry goods coating or infiltration layer abbreviates mould plating method as, it is characterized in that making an air retaining wall in advance in mold cavity, and after casting, this air retaining wall is an one with casting liquid cementing, becomes the foundry goods skin; This air retaining wall can be the coating of powder metallurgy powder, and the powder metallurgy that also can be compacting, sinter molding is (as TiC, TiN, WC, Al
2O
3Steel Bond Hard Alloy etc.) air retaining wall also can be the air retaining wall that other material (as titanium, nickel, steel composite ceramics etc.) is made.In a word,,, select suitable material for use, make required shape, the air retaining wall of dimensional thickness corresponding to the position that needs coating by the requirement of workpiece.
Description
The present invention plates method hereinafter to be referred as mould, and it is to make foundry goods produce the method for overlay coating or infiltration layer in casting cycle.
By traditional method, carrying out coating at workpiece surface handles, be to adopt physics gas sedimentation (PVD method such as plasma spraying, heating sputter) and chemical Vapor deposition process (CVD method) and electrochemical plating etc., the expense height, the technology that has, technology are very complicated, technology such as plating hard alloy layer on workpiece is just very complicated, generally adopts PVD method or CVD method.
Mould plating method provides a kind of method easy, low expense, makes workpiece produce the coating or the infiltration layer of one deck excellent property.
Mould plating method is the method that produces overlay coating, infiltration layer or inlay in the casting cycle, it is characterized in that making an air retaining wall in advance in mold cavity, and after casting, this air retaining wall is an one with casting liquid cementing, becomes the foundry goods skin; This air retaining wall can be the coating of powder metallurgy powder, and the powder metallurgy that also can be compacting, thermal sintering is (as TiC, TiN, WC, Al
2O
3Steel Bond Hard Alloy etc.) air retaining wall also can be the air retaining wall that other material (as titanium, nickel, steel, composite ceramics etc.) is made.In a word,,, select suitable material for use, make the air retaining wall of required shape, size, thickness corresponding to the position that needs coating by the requirement of workpiece.The method that air retaining wall is made in precision casting is that air retaining wall is made on the wax-pattern, coats formwork materials such as quartz sand then, wax-pattern boil melt remove after, air retaining wall has just been stayed in the mold cavity.In order to prevent coating oxidation at high temperature, decarburization, need mold be entangled and space is between the two filled up as far as possible as box in the outer way that adopts secluding air of mold with a good airproof performance, only stay pouring gate outside box.In order to prevent air retaining wall when casting cracking, be with the mold preheating.
After adopting the present invention, plating (oozing) layer is once formed when casting, the quality height, expense is low, technology is simple.Select suitable powder will make plating (oozing) layer produce required performance, as adopting cemented carbide powder (as TiC, TiN, WC, Al
2O
3Deng), will make workpiece surface have high hardness, adopt materials such as titanium, nickel, copper, aluminium will make the workpiece antirust, anti-corrosive, adopt zinc powder, will make cast(ing) surface produce the zinc infiltration layer, produce the zinc infiltration layer when making pot and will replenish the means that zinc provides to people.
Embodiment 1, mould plating method can be used in the various casting techniques, when precision casting, need position, size, shape, material and the thickness of coating corresponding to workpiece, on wax-pattern, carry out air retaining wall, the air retaining wall that for example will make shape places in the casting die cavity, after the casting, air retaining wall is done the casting formwork more just with the wax-pattern one on this wax-pattern, remove after the wax-pattern, air retaining wall just has been embedded in the formwork.
Embodiment 2, mould plating method can be applicable to industries such as electrolysis, machinery, mould plating method can select for use multiple materials with different properties to make air retaining wall at a plurality of positions of workpiece, with the particular requirement that reaches workpiece for example during iron pan, can apply the infiltration layer of zinc at the pot concave surface, the content that just can increase zinc during cooking applies the plating coating of aluminium at the protruding back of pot, improve wearing quality.Again for example, make the anode electrolytic cell surrounding layer with thin titanium board, placing becomes air retaining wall again in the mold, and inner chamber is cast with copper, aluminium, and forming inside is copper, aluminium, and skin is the anode electrolytic cell of titanium.
