Description
Technical field
The present invention relates to a kind of composite containing stainless steel, and in particular to a kind of by ceramics, simple metal and stainless steel double
The material of conjunction.
Background technology
Stainless steel and ceramic material are industry and apply two kinds of extremely wide materials, stainless steel material acid and alkali-resistance in living
The mechanical properties such as corrosivity is good, stretching, bending resistance, shock resistance are good, and then hardness height, wearability are good for ceramic material, and two kinds of materials are because of tool
Standby different characteristic, often applied to different field.
430 stainless steels are widely used one kind in stainless steel series, because its thermal coefficient of expansion is smaller than austenitic stainless steel,
Used frequently as building decoration, the system of supplying hot water, sanitary apparatus, home-use durable utensil etc..430 stainless steels are as above-mentioned
Maximum shortcoming is the corrosion for the chemical substance for atmospheric corrosion poor resistance, being highly prone in air in, so as to send out
Raw surface oxidation.And 430 stainless steel to acid tolerance it is also poor, get rusty easily in use.How to make 430 stainless
Steel overcomes easy get rusty with perishable shortcoming to be an important research topic in use.
Application No. 201010568591.4 it is entitled《The connection method of stainless steel and aluminium oxide ceramics and obtained connection
Part》Chinese patent in set between stainless steel and aluminium oxide ceramics a metafiltration ripple as connection medium there is provided one kind, lead to
The mode of solid-state diffusion is crossed, above-mentioned material is combined into one with hot-pressed sintering furnace.This method complex process, and also need to use
Substantial amounts of argent, cost is high.
The content of the invention
For the shortcomings of the prior art, the invention provides a kind of answering using 430 stainless steels as base material
Condensation material, is greatly improved the corrosion resistance of 430 stainless steels.
The technical problems to be solved by the invention are achieved by the following technical programs：
Stainless steel composite material in the present invention includes ceramic layer, cushion and stainless steel layer, and the ceramic layer is oxidation
The cerium oxide that mass percent is 15-25% is added in zircon ceramic, the zirconia ceramics, cushion is Nb metal levels, Mo metals
One kind in layer, stainless steel layer is 430 stainless steels；Ceramic layer, cushion and stainless steel layer are sequentially overlapped, and are made by sensing heating
Three is fused into one.
Ceramic layer and stainless steel layer can not be well bonded together by prior art, and one layer of setting is pure therebetween
Ceramic layer and stainless steel layer can both be organically combined after the cushion of metal, sensing heating, and when the composite wood
Material is carried out as structural member in use, cushion can be as buffer zone, and the hit energy outside absorption is multiple during lifting is of the invention
The mechanical property of condensation material.
Zirconia ceramics has high tenacity, high-flexural strength, high-wearing feature and excellent heat-proof quality, it is most important that its
Thermal coefficient of expansion is close to steel, so zirconia ceramics adhesion when the composite formed with 430 stainless steels is used is good,
When running into hot environment, the composite in joint crack will not occur because of the difference of thermal coefficient of expansion, so as to cause material
Material failure.Meanwhile, zirconia ceramics is pure white, is easily mixed colours, and can change the color of ceramic layer the need for bonded composite,
Meet the demand of multiple color.Cerium oxide exists in ceramic systems as network modifying oxide, it is impossible to separately formed, still
There is very big influence when being engaged with zirconium oxide to ceramics construction and performance, by controlling the addition of cerium oxide to control
The coefficient of expansion of ceramics, finds, the addition of cerium oxide is made pottery when being mass percent 15-25% in the present inventor's practice
Enamel coating is optimal, and its coefficient of expansion and metal level are closest.
Nb and Mo elements are all the conventional addition element in stainless steel, Nb and Mo simple metal possesses excellent corrosion resistance and steady
It is qualitative, it is in the stainless steel of many different trades mark to add both elements to improve the property of stainless steel more.In the present invention, utilize
The good amalgamation of Nb and Mo simple metal and stainless steel, it is stainless during can making follow-up sensing heating from both metals
It is more close that steel is combined with simple metal cushion.
The zirconia ceramics used in the present invention can select 2-3% Y during firing2O3It is used as sintering aid.
Y2O3Sintering aid can effectively lift the calcination efficiency of zirconia ceramics, and can increase the porosity of zirconia ceramics, make oxygen
That changes that zircon ceramic and simple metal cushion engage during sensing heating is more close.
Further preferably, when the thickness of ceramic layer, cushion and stainless steel layer is all 4-8mm, three kinds of materials can be most
For closely engagement, especially when the thickness of ceramic layer, cushion and stainless steel layer is all 5mm, prepared composite
It is tightly combined, shock resistance is good.
Ceramic layer, cushion and stainless steel layer is set to be bonded together using the method for sensing heating in the present invention, to avoid
Easily oxidation forms the characteristic of oxide skin to 430 stainless steels in atmosphere, and the sensing heating is carried out in a vacuum furnace, vacuum drying oven
Vacuum is 10-5-10-4Pa is advisable.When sensing heating selects high-frequency alternating current, the rate of heat addition is too fast, is unfavorable for ceramic layer with delaying
The engagement of layer, cushion and stainless steel layer is rushed, the scaling loss of stainless steel is easily caused, and the thickness of heating is usually no more than 3mm；And
Heating frequency is too low, then completely can not welding ceramic layer and cushion, cushion and stainless steel layer；Therefore the frequency of sensing heating makes
With intermediate frequency, preferably 6-10KHz, junction temperature when ceramic layer, cushion and stainless steel layer sensing heating is 800-
1200 DEG C, engaging time when ceramic layer, cushion and stainless steel layer sensing heating is 15-30 minutes.
If the ceramic layer of selection, cushion and stainless steel layer are partially thick, junction temperature and engaging time can be suitably lifted.This
Found in inventor's practice of invention, when junction temperature when ceramic layer, cushion and stainless steel layer sensing heating is 1057 DEG C,
The splicing results of ceramic layer and cushion, cushion and stainless steel layer are optimal.
The present invention has the advantages that：
1st, the scheme in the present invention can effectively engage 430 stainless steels and zirconia ceramics, obtain the corrosion resistance of 430 stainless steels
To great improvement.
2nd, the composite containing stainless steel in the present invention is tightly combined, and shock resistance is good.
Embodiment
Present disclosure is further described below by embodiment.
Y of the ceramic layer from addition 3%2O3The zirconia ceramics calcined out as sintering aid, wherein addition quality percentage
