The microstructure of a material is one of the most important parameters – if not THE most important – to be used to assess the quality of a newly developed material or component. Therefore, information about the microstructure can be obtained by porosity measurements or strength tests, since these properties are greatly influenced by the microstructure. Directly, the microstructure of e.g. technical ceramics can be studied using a wide range of methods that have been available to industry and the end-user market since the last century to complement conventional optical microscopy.
The newly developed high temperature resistant coatings are now called CerCoat®-HT. The basis is a ceramic suspension that enables adhesion to metallic substrates with special binders. A temperature-resistant bonding is achieved by a heat treating process between 500°C and 650°C, which ensures the subsequent application temperature up to at least 650°C.
Vacuum hot casting is used at WZR to produce first parts of series character quickly and cost-effectively. A major improvement has now been achieved in the preparation of the hot casting feedstock: WZR has now succeeded in both extremely homogeneous and abrasion-free production. The ceramic components produced in this way are characterised by an undyed surface, very low porosity and high bending strength.
For our birthday celebration we held a symposium where we were able to show the whole range of ceramics at WZR. From energy technology to refractories to dental ceramics, from structural ceramics to membrane reactors to an overview lecture 25 years of WZR.
Have you ever felt the impulse to observe your ceramic while sintering? Would you like to follow the interaction between refractory material and slag? You would like to watch the molecules at work as they polymerize?
After we had already announced in a BLOG post in November 2020 that we would soon be getting a new furnace for sintering metals, the time finally came last week. We unpacked the furnace, put it into operation and are currently working on the first sintering programs for our 3D-printed metal parts.
