Siemens

The perfect precision cut on complex turbine components

Siemens Industrial Turbomachinery prepares turbine components for materialographic analysis. The parts are often small and uneven, with additive manufactured components, making them very tricky to clamp and cut. Siemens wanted a cutting machine that was precise, fast and efficient – and gave them unlimited clamping options. Our solution was the Secotom-60 precision cutting machine.

CIE Praga Louny Case story

Optimized quality tests reduce costs by 50 %

Time plays a vital role within the production process at CIE Praga Louny, a.s., that produces mainly machine parts. And After installing an additional new production line, they wanted a more efficient method for quality testing the hardening of produced flanges. In cooperation with Struers, the company developed a new sectioning process that increased feed speed by 50 %, reduced costs by 50 %, and increased cut-off wheel lifetime three times.

Copper Acetate Dendrites

What is metallography?

In short, metallography can be defined as the science and art of studying the microstructure of different metals and metal alloys.

Read this article to understand the differences between metallography and materialography and how does that impact the choice of preparation methods?
We take a closer look at the history, the applications, and the analysis of both metallography and materialography.

Electrolytic preparation

‘Can you prepare this for me real quick?’

Electrolytic preparation offers a range of benefits compared to mechanical preparation, not least a shortened preparation time and virtually deformation-free material removal, especially in soft and tough materials. But it has drawbacks, too. So, when is electrolytic preparation most effective?

In this article, the results of a Round Robin Test, done by working group “Sample Preparation” of German Materials Society, involving 10 different labs to assess the drawbacks and benefits of electrolytic preparation, giving detailed recommendations for certain materials in comparison to mechanical preparation. It’s a must-read for labs that are considering electrolytic preparation as a way to meet fast turnaround times.

Austenite Grain size

Grain size determination on austenitic steels

Grain size is a key parameter in materials technology. But automatic determination of grain size in high-alloy austenitic steels can be tricky due to twinning and other specific problems caused by materials properties.

This article outlines the results of a Round Robin Test, done by working group “Sample Preparation” of German Materials Society. It shows the possibilities when preparing corrosion resistant austenitic steels for grain size measurements, using mechanical and electrolytical preparation methods, and illuminates contrasting by chemical and electrolytical etching.

Hardness testing on HVOF coatings

Hardness testing and microscopic evaluation of carbidic HVOF spray coatings

Carbidic coatings are used as wear protection in certain industries – and hardness is a key indicator of coating quality. But what is an acceptable hardness fluctuation range and what causes fluctuations when hardness testing HVOF (high velocity oxygen fuel) spray coatings?

In this article, the results of a Round Robin Test, done by working group “Sample Preparation” of German Materials Society, involving 19 companies and institutes to determine the potential hardness fluctuation range of carbidic HVOF spray coatings. The article describes the preparation and methods and microscopic evaluation in detail, giving you a clear methodology and indicator of acceptable hardness fluctuations.
