Abstract
The utility model relates to a metal cooker with a hard anticorrosion surface layer. The metal cooker comprises a layer of metal substrate and is characterized in that a surface layer of amorphous state organization structure composed of metals and nonmetals is composited on the surface of the metal substrate, wherein metallic elements of the surface layer comprise cobalt, nickel, tin, iron, copper and the like, and non-metallic elements of the surface layer includes phosphorus, boron, nitrogen and the like; the metal substrate is a steel plate, cast iron, aluminum or aluminum alloy materials and can also be composite materials of several metals; and the thickness of the surface layer is below 25 microns. The metal cooker with the hard anticorrosion surface layer is large in surface hardness, good in abrasion resistance and high-temperature resistant, has high capabilities of acid, alkali and salt resistance and the like, and meets requirements of food sanitation.
Description
Technical field
The utility model belongs to a kind of cooker, particularly a kind of metal cooking appliance with hard corrosion resistant surface layer.
Background technology
Cooker (frying pan, inner container of electric cooker, steamer etc.) adopts individual layer sheet material in a large number with sheet material at present, and what mainly use is iron plate, aluminium sheet or corrosion resistant plate.Use individual layer iron plate to use sheet material,, the defective of easy corrosion is arranged though price is low as cooker; Use single layer aluminium sheet use sheet material, though fast, the corrosion resistant advantage of heat conduction in light weight is arranged, have that high temperature strength is poor, the low not wear-resisting and use for a long time of case hardness can make that the absorption people scale of construction of aluminium is excessive, is prone to diseases induced defective as cooker; Use the individual layer corrosion resistant plate to use sheet material, though stainless corrosion-resistant, wear-resisting advantage is arranged, Heavy Weight, price height as cooker.Also having at present cooker to use material is to adopt rolling method to process composite board as the aluminium sheet two sides as corrosion resistant plate the centre; It has combined the advantage of aluminium and stainless steel material; But the thickness of corrosion resistant plate is more than the 0.4mm, still has Heavy Weight, defective that price is high.
For the surface coating of various metal cooking appliances, commonly used have coatings such as polytetrafluoroethylene (PTFE), and also having a kind of is the protective layer that method electrolysis such as electricity consumption chemical plating, chemical plating, hot-dip are coated with metal or metal alloy such as copper or copper alloy, nickel, iron nickel.And the institutional framework of these coat of metals belongs to crystalline state basically, occurs the big intergranular defective that waits in space easily, and for coat of metal reaches certain rigidity, wear-resisting, high temperature resistant and corrosion resistance, its thickness all will reach more than 25 microns.
Summary of the invention
The purpose of the utility model provides a kind of surface coverage at metal base by the metal cooking appliance with hard corrosion resistant surface layer by one or more metals and the nonmetal amorphous microstructure superficial layer of forming, to overcome the deficiency of prior art.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of metal cooking appliance with hard corrosion resistant surface layer comprises the layer of metal base material, is characterized in: in the surface recombination of said metal base by the superficial layer of one deck by metal and the nonmetal amorphous microstructure structure of forming.
The thickness of said superficial layer is less than or equal to 25 microns.
Metallic element in the superficial layer of the amorphous microstructure structure of said metal and nonmetal composition comprises cobalt and/or nickel and/or tin and/or iron and/or copper; Nonmetalloid in the superficial layer comprises phosphorus and/or boron and/or nitrogen.
Said metal base comprises the composite of steel plate, cast iron, aluminium, aluminum alloy materials and several kinds of metals.
Because the superficial layer of the utility model is the amorphous microstructure structure of metal and nonmetal composition, because the atomic arrangement of amorphous microstructure structural disorder, it does not have the intergranular defective of metal crystalline state institutional framework, and porosity is little.Ordinary circumstance has had the thickness more than 5 microns, just can show its good corrosion-resistant various characteristics that waits.Have the compound cooker of metal base of this amorphous microstructure superficial layer, case hardness is big, wearability good, high temperature resistant and have stronger abilities such as acidproof alkali salt, meets the food hygiene requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail.
Embodiment 1 (Fig. 1): the utility model is at first with the foundry pig iron ingot; With the method for die cast, process the cast-iron blank of frying pan, and frying pan cast-iron blank surfaces externally and internally is carried out thick sanding to remove oxide layer; Carry out surperficial finish turning and sanding again and handle, form the cast iron base material 2 of frying pan; Then with above cast iron base material through alkali degreasing, water clean, operations such as acid is invaded, water cleaning; Again with the surfaces externally and internally of above cast iron frying pan, through the method for chemical reaction, with metallic element cobalt, iron and nonmetalloid boron; Form the superficial layer 1 of amorphous microstructure; The thickness of this amorphous microstructure superficial layer 1 is the 5-10 micron, carries out clear water at last and cleans, and forms antirust and resistant to elevated temperatures compounded cast iron frying pan.
Embodiment 2: the utility model is at first with the 2.5mm aluminium sheet; By the metal die drawing and forming is the soup milk pot with definite shape; And the surfaces externally and internally of soup milk pot carried out finish turning and sanding processing, processed base thickness 2.5mm, aluminium matter base material 2 that side 1.0mm-2.0mm is thick; Then through alkali degreasing, water clean, surface modulation is handled and invade in advance, operation such as water cleaning; Again with inside and outside the above aluminium matter base material 2, through the method for chemical reaction, with metallic element nickel, tin and nonmetalloid phosphorus; Form the superficial layer 1 of amorphous microstructure; The thickness of this amorphous microstructure superficial layer 1 is the 15-20 micron, carries out clear water at last and cleans, and forms big, the wear-resisting compound soup milk pot of case hardness.It with market on the centre of selling for the aluminium sheet two sides is that the compound steel cooker of corrosion resistant plate is compared, have the characteristics of light weight and cost-saving.
Embodiment 3: the utility model is flat bottom cooker at first with the 2.0mm aluminium sheet by the metal die drawing and forming, and the surfaces externally and internally of frying pan is carried out the sanding processing; Then through alkali degreasing, water clean, operations such as acid is invaded, water cleaning; Outer surface (or surfaces externally and internally) at above aluminium sheet base material deposits one deck iron layer with electrochemical method again, and iron layer thickness 0.05-0.2 millimeter is as the base material 2 of composite frying pan; Again with inside and outside the above base material 2; Through the method for chemical reaction, with the superficial layer 1 of metallic element cobalt, nickel and nonmetalloid nitrogen formation amorphous microstructure, the thickness of this amorphous microstructure superficial layer 1 is the 10-15 micron; Carry out clear water at last and clean, accomplished the production of big, the antirust ferro-aluminum composite frying pan of case hardness.This composite frying pan can also use on electromagnetic oven.
The content of not doing in this specification to describe in detail is this area professional and technical personnel's known prior art.
