The purpose of this utility model can be achieved through the following technical solutions:
A kind of packaging system for hot isostatic pressing Ceramic Balls jacket sintering process, this packaging system comprises graphite tank, graphite basket, encapsulated layer and Ceramic Balls unit, described graphite basket is arranged in graphite tank, is provided with encapsulated layer bottom graphite basket, and described Ceramic Balls unit is arranged on encapsulated layer.
The interlayer that described Ceramic Balls unit comprises ceramic layers of balls and is arranged between ceramic layers of balls, the number of plies of described ceramic layers of balls is determined by the height of graphite tank and graphite basket.
Described ceramic layers of balls is laid by multiple Ceramic Balls and is formed, and ceramic layers of balls is at least 2 layers, and described Ceramic Balls is silicon nitride ceramic ball, and the densification of this silicon nitride ceramic ball is at least 93%.
Described interlayer comprises graphite network and metallic tin powder, described metallic tin powder be laid on respectively graphite network up and down two on the surface.
Described graphite top tank structure is coated with one deck boron nitride powder.
The inner and outer wall of described graphite basket is all coated with one deck boron nitride powder, and mainly in order to prevent under the high temperature conditions, encapsulated layer and graphite basket bond.
Described graphite tank adopts high strength, high purity graphite material is made, and described graphite basket adopts common graphite to make, and mainly plays buffer action.
Described encapsulated layer is glass powder layer or metallic tin bisque.
Described graphite network adopts common graphite to make, and its surface is coated with one deck boron nitride powder.
Utilize silicon nitride ceramic material and tin metal that the principle of chemical reaction does not occur under the high temperature conditions, the fusing point of metallic tin is low, the utility model device is put into high vacuum furnace, vacuumize, and heat up, when temperature is elevated to the fusing point of metallic tin, metallic tin starts fusing, now, high temperature nitrogen SiClx Ceramic Balls can be wrapped up completely by tin liquor, thus make silicon nitride ceramic ball and the external world completely isolated; When carrying out HIP sintering, gaseous tension can be delivered to silicon nitride ceramic ball surface by tin liquor, promotes the sintering process of stupalith, can reach the glass bag technique effect that current ceramic boundary adopts.
Compared with prior art, the utility model has following characteristics:
1. simple to operate: to adopt the utility model device, without the need to loaded down with trivial details glass bag vacuum packing system, only need simple vacuum oven just can meet the demands, easy to operate, can industrialization production requirements be met;
2. safe and reliable: the metallic tin adopting low melting point, as long as temperature exceedes the fusing point of metallic tin, just can guarantee that silicon nitride ceramic ball is wrapped up by tin liquor completely, is isolated from the outside effective;
3. cost is low: after terminating at every turn, and only need to change graphite basket and graphite network, metallic tin can reuse, and tooling cost is low.
