Thermal Barrier Coatings (TBC) for more than 650°C

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.

How to avoid stresses in your component?

Have you ever had the problem that a metal door just wouldn’t close in the summer, and in the winter cold air came through gaps even more so?

Maybe not, but you’ve certainly had a glass shatter because you poured water inside that was too hot.

Further development of vacuum hotcasting

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.

XRF vs. XRD of ceramics

“Why do you recommend X-ray diffraction analysis and not X-ray fluorescence analysis -as you did on our last job?”
“Why should I do both? It gives me the same result, after all.”

Metal sintering

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.
