Fabrication procedure of stainless steel and zirconia ceramic composite
Time: 2020-01-17   Writer: mingrui
The performance of zirconia ceramics itself has been very excellent, if it is combined with high-quality stainless steel materials together, the advantages of this composite is not even more obvious?But it is clear that the stainless steel can be combined with zirconia ceramics, and then in step.Zirconia ceramics with high toughness, high bending strength, high wear resistance, as well as excellent thermal insulation performance, thermal expansion coefficient and other advantages favored by users.Now it has a number of one unique, that is stainless steel want to be combined with sintering, resulting in a stainless steel and zirconia ceramic composite.In the actual production, the required materials should be prepared first.

In addition to stainless steel and zirconia ceramic parts, molybdenum foil and nickel foil are also required as auxiliary materials.The zirconia ceramic is then deposited on the surface of the nickel metal layer, the process is simple, as long as the zirconia ceramics, molybdenum foil, nickel foil and stainless steel pieces together into a connection mold can be.In this way, the molybdenum foil and nickel foil are sandwiched between the zirconia ceramic piece and the stainless steel piece, and the molybdenum foil is adjacent to the nickel metal layer on the zirconia ceramic piece and the nickel foil is adjacent to the stainless steel piece.Then the connecting mould was put into a hot pressing sintering furnace, and the zirconia ceramics, molybdenum foil, nickel foil and stainless steel were diffusely connected in solid phase under the protective atmosphere, so as to obtain the composite of stainless steel and zirconia ceramics.After the workpiece is cooled, it can be removed from the hot press sintering furnace, resulting in the previously described stainless steel and zirconia ceramic composite.

Because the melting point of zirconia is higher than that of stainless steel, so stainless steel will be melted before zirconia, as long as the operation in accordance with the method, the two can be very good together.To pay attention to the details of the process, operational problems, as well as the problems of the vacuum furnace, a good product must have a full set of process specifications, to determine the product quality standardization, zero fault, flow can, modular and other characteristics.Such ability lets the customer buy rest assured, use rest assured.
