Abstract
The utility model provides a kind of NEW TYPE OF COMPOSITE zirconium load bearing board, including carborundum plate, corundum-mullite layer is enclosed with outside carborundum plate, the upper and lower end face of corundum-mullite layer is provided with some projections, the non-projection in upper and lower end face of corundum-mullite layer is partially covered with zirconia layer, and the thickness of zirconia layer is identical with the thickness of projection.NEW TYPE OF COMPOSITE zirconium load bearing board provided by the utility model, improve the topology layout at four angles of surface layer, improve its mechanical strength, extend service life, reduce production cost.
Description
Technical field
It the utility model is related to a kind of load bearing board, more particularly to a kind of mechanical strength is good, the compound zirconium of service life length is held
Burn plate.
Background technology
Load bearing board is to be used for magnetic material industry, backing plate used in sintered products.Traditional compound zirconium load bearing board, surface layer
It is corundum-mullite below surface layer, the mechanical strength of zirconium oxide is poorer than corundum-mullite using zirconium oxide.Four angles of surface layer
To support force, due to the deficiency of mechanical strength, four angles of surface layer are easily damaged, and cause the service life of compound zirconium load bearing board
It is short, improve production cost.
Utility model content
The technical problems to be solved in the utility model is to overcome the defects of existing, there is provided a kind of NEW TYPE OF COMPOSITE zirconium load bearing board,
Service life is grown, and reduces production cost.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of NEW TYPE OF COMPOSITE zirconium load bearing board, including carborundum plate, corundum-mullite is enclosed with outside the carborundum plate
Layer, the upper and lower end face of the corundum-mullite layer is provided with some projections, the non-projection in upper and lower end face of the corundum-mullite layer
Zirconia layer is partially covered with, the thickness of the zirconia layer is identical with the raised thickness.
Further, the profile of the corundum-mullite layer is class cuboid, and the projection is arranged on the corundum and do not come
Four angles of rock layers upper and lower end face.
Further, between carborundum plate and the corundum-mullite layer, the corundum-mullite layer and zirconia layer it
Between using compound suppressing be molded.
A kind of NEW TYPE OF COMPOSITE zirconium load bearing board of the utility model, improve the topology layout at four angles of surface layer, improve its machinery
Intensity, service life is extended, reduce production cost.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 schematic top plan view.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in Figure 1, 2, a kind of NEW TYPE OF COMPOSITE zirconium load bearing board, including carborundum plate 1, the outside of carborundum plate 1 are enclosed with
Corundum-mullite layer 2, the profile of corundum-mullite layer 2 is that class cuboid (is not complete length because backing plate practical application needs
There is specially treated at cube, four angles), four angles of the upper and lower end face of corundum-mullite layer 2 are each provided with a projection 3, corundum
The non-projection in upper and lower end face of mullite layer 2 is partially covered with zirconia layer 4, the thickness and the thickness phase of projection 3 of zirconia layer 4
Together.High mechanical strength, service life length, can be that manufacturing enterprise saves by the use of the raised as support force of corundum-mullite material
A large amount of recruitment costs and material cost are saved, improve considerable economic benefit.
Between carborundum plate 1 and corundum-mullite layer 2, compound pressure is used between corundum-mullite layer 2 and zirconia layer 4
Type is made, there is firm bond strength, low thermal coefficient of expansion, good thermal shock stability between every layer.
A kind of NEW TYPE OF COMPOSITE zirconium load bearing board of the utility model, improve the topology layout at four angles of surface layer, improve its machinery
Intensity, service life is extended, reduce production cost.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc.,
It should be included within the scope of protection of the utility model.
