What Are The Common Welding Methods Of Zirconia Ceramics


What Are The Common Welding Methods Of Zirconia Ceramics The density of zirconia ceramics is between 5.95-6.05 g/cm3. It is a high-composite new material product, which is widely used in the field of structural ceramics. It has self-lubricating properties, which can solve the pollution caused by the medium and the inconvenience of adding; high toughness, high temperature resistance, no static electricity, good insulation, strong corrosion resistance and other advantages. So what are the differences between solid phase diffusion welding and brazing of zirconia ceramics? Pintejin Ceramics is a high-tech enterprise specializing in the production and precision machining of ceramics. At present, Pintejin Ceramics has a number of CNC machine tools including Beijing Jingdiao, as well as machining equipment such as precision grinders and forming equipment such as isostatic pressing and sintering furnaces. And provide full-process services to ensure stable product quality and fast delivery. Below, the editor of Pintejin Ceramics will introduce to you the common welding methods of zirconia ceramics.
  • The first thing to say is that fusion welding is not suitable for welding zirconia ceramic structural parts, and solid-phase diffusion welding and brazing are more suitable for product welding, and have been applied. The difference between solid-phase diffusion welding and brazing is as follows: solid-phase diffusion welding has avoided the problem of wetting of metal to zirconia ceramic structural parts, but solid-phase diffusion welding requires the entire welding interface to maintain close contact, so for the machining interface The precision requirements are particularly high, and solid-phase diffusion welding is not suitable for complex interfaces and large-area welding; there are two methods for brazing ceramics. In addition to the active solder method, there is another method, which was developed relatively early. , is a surface metallization method of zirconia ceramic structural parts used in conjunction with conventional brazing filler metals. But it has a disadvantage that the process is very complicated. Brazing is very limited by wettability, but it does not require high machining accuracy of the welding surface, and is more suitable for complex interfaces and large-area welding.
  • Secondly, in addition to these, the solid-phase welding method of zirconia ceramic structural parts is not only diffusion welding, but also microwave welding and friction welding, but this method has many shortcomings and is not yet mature. For example, microwave welding is not suitable for free and metal welding. It uses the characteristics of zirconia ceramic structures to absorb microwaves and then performs heating and diffusion bonding; friction welding is difficult to achieve results for hard and brittle ceramic materials, which is applied in an instant. Very large pressure achieves bonding through large deformation, so microwave welding and friction welding have shortcomings and are not yet mature.

The above is about the common welding methods of zirconia ceramics. Whether it is metal filler material welding zirconia ceramic structural parts or zirconia ceramic structural parts and metal welding, there will be some combination problems, so choose the appropriate one according to the actual specific situation. The welding method can reflect the quality and aesthetics of the product.
