Source: https://www.innovacera.com/news/ceramics-and-metals-to-achieve.html Ceramics are often referred to as inorganic non-metallic materials. It can be seen that people directly position ceramics on the opposite side of metal. After all, the performance of the two is worlds apart. But the advantages of the two are too prominent, so in many cases, it is necessary to combine ceramics and metals, each showing their strengths, so the technology-ceramic metalization technology was born. Especially with the advent of the 5G era, the power of semiconductor chips continues to increase. The development trend of lightness and high integration is becoming more and more obvious, and the importance of heat dissipation is also becoming more and more prominent. This undoubtedly puts more stringent requirements on package heat dissipation materials. In the packaging structure of power electronic components, the packaging substrate serves as a key link for connecting the upper and lower parts ...

The Ceramic Plungers are mostly made of alumina (Al2O3) or zirconia (ZrO2) ceramics which have superior wear resistance, corrosion resistance, high-temperature resistance and impact resistance properties etc. When using ceramic plungers instead of tungsten carbide you get longer life on HP-seals and the plunger itself. And a high surface finish will increase the wear life of parts, allowing for lower replacement costs and better performance. INNOVACERA decades of experience in tight tolerances and high surface finishes have helped us build relationships.

In sliding wear environments, hard counter faces that do not interact with each other are an advantage. The engineering grades of Alumina are typically 25-50% harder than zirconia grade so in sliding wear environments or pure abrasive wear, where third body abrasive wear particles are present, alumina often outperforms Zirconia. However, in erosive wear environments such as those caused by an abrasive slurry impacting a wear part such as an oilfield valve, Zirconia can be the best performer as it’s high toughness reduces the spread of impact cracks and the microfracture of the surface which generate erosive wear debris and surface damage. When running an engineering ceramic against a dissimilar material it’s not always the case that the softer material performs poorly. Y-TZP r...
