Can Stainless Steel Be Sintered With Zirconia Ceramics?

Can Stainless Steel Be Sintered With Zirconia Ceramics?

Zirconia ceramics have the advantages of high toughness, high bending strength and high wear resistance, excellent thermal insulation, thermal expansion coefficient, and so on. So some friends want to know: can stainless steel be sintered with zirconia ceramics?

Mingrui ceramic senior engineer answers questions online for you: in terms of professional technology, it is actually possible, which requires a manufacturing method of stainless steel and zirconia ceramic composites, which can include the following steps:

1. Prepare stainless steel parts, zirconia ceramic parts, molybdenum foil, and nickel foil; deposit nickel metal layer on the surface of the zirconia ceramic parts.

2. Put the parts, molybdenum foil, nickel foil, and stainless steel parts into a connecting die, so that the molybdenum foil and nickel foil are sandwiched between the zirconia ceramic parts and the stainless steel parts, and the molybdenum foil is adjacent to the nickel-metal layer on the zirconia ceramic parts. nickel foil is adjacent to stainless steel parts.

3. The bonding die is put into a hot pressing sintering furnace, and the solid phase diffusion bonding of zirconia ceramic parts, molybdenum foil, nickel foil, and stainless steel parts into stainless steel and zirconia ceramic composites is made in a protective atmosphere.

4. Take out the stainless steel and zirconia ceramic composite parts after cooling.

Why do we need to follow the above steps? it is because the melting point of zirconia is 2715 ℃, and the melting point of stainless steel should be 1399-1455 ℃. Stainless steel usually melts before zirconia. Therefore, it is necessary to use the above methods before they can be combined.

Above information provided by Mingrui Ceramics, we mainly engaged in the custom and processing of zirconia and alumina ceramic structural parts. For the composite parts, ceramic pump and ceramic valve are the most representive products.
