Failure analysis on ceramics

Analysis

Failure analysis and test procedures of technical ceramics in our test laboratory

The assurance and control of the quality of industrially manufactured products, especially ceramic components, is an essential pillar in manufacturing. Here the credo is “better to play it safe”, especially since it is a frequent customer request. Many factors, such as shaping up to sintering, must be kept in mind at the same time.

Should an unexpected failure of the plant or a product occur at the customer’s site: we are there for you! The damage analysis deals with the recording of the occurring damage and investigates the possible causes so that you can quickly return to the normal planning cycle.

Criteria

Testing of ceramics according to scientific criteria

Our approach is strictly based on scientific criteria that allow an independent and objective evaluation. A description and stock-taking of the found facts is the basis for the cooperation. The resulting hypothesis is then tested by means of chemical and physical experiments and adjusted if necessary. At the end of this cycle there is a description of the complete facts of the case up to the alleged cause. These findings can now be used to remedy the problem or to adapt the process so that it runs even better in your interest and can be verified.

Limitations

The limits of damage analysis of ceramics

Since the foundation of the company, we at WZR ceramic solutions GmbH have focused on long-term and close customer relations. During the process, both parties may exchange confidential information that is essential for analysis and, above all, interpretation. The exact evaluation therefore requires your involvement and a discussion in the course of which the objective results are applied to the process, which you know in detail even better than we do. Your assistance is therefore a basic building block.
Depending on the preparation and condition of the sample, the limits of the equipment are about 3 nm for spot sizes (“measurement resolution”) and 300,000x maximum magnification. The samples themselves can be placed in the scanning electron microscope and observed up to sizes of 150 mm diameter and heights of up to approx. 40 mm. Depending on the nature of the samples, preparation to the desired areas or suitable sizes is necessary.
The limits of the analyses and are discussed in detail with you in advance of the analysis.
