As we all know, zirconia ceramic is a Material with high resistance to crack propagation. It has high melting point, high boiling point, high hardness, is an insulator at room temperature, and has excellent properties such as electrical conductivity, low thermal conductivity and high strength at high temperatures. Therefore, zirconia ceramics are widely used in various fields. Zirconia ceramic can be used as a mold for wire forming and as an insulating pipe sleeve. At the same time, it is often a good choice for insulating rings in high-temperature environments.
Stainless steel ( Stainless Steel) is steel with stainless steel and corrosion resistance as its main characteristics, with a chromium content of at least 10.5% and a maximum carbon content of no more than 1.2%. Stainless steel is stainless acid-resistant steel< /span>'s abbreviation for resistanceAir、Steam、Water and other weakly corrosive media or stainless steel are called stainless steel; while those that are resistant to chemically corrosive media (acid, acid, etc.)Alkali、Saltetc. chemical etching) corroded steel is calledAcid-resistant steel.
Zirconium oxide ceramics and stainless steel are both excellent materials in themselves. If combined If the two are combined, it is conceivable that the superior performance of this composite part will be more prominent. Since the melting point of zirconia is higher than that of stainless steel, stainless steel generally melts before zirconia, so during the processing, zirconia and stainless steel cannot be sintered together. So how are zirconia ceramics and stainless steel combined? Common combined processing methods include: high-temperature adhesive bonding, threaded and screw hole connections, and welding. Common composite products include: cermet plunger pumps, oil well ceramic plunger cylinder liners, cermet lined pipes, etc.
