Science for Solids

Materialographic Preparation Process

ATM manufactures machines for materialography (metallography) used in quality control processes.

Metal parts require thorough testing, for instance after the sintering process. ATM’s wide range of high-quality machines for cutting, polishing and etching allow for a perfect surface preparation as prerequisite for reliable microstructural analysis.

Thanks to automated solutions, such as the innovative Cut-off Machine Brillant 250, sample preparation is convenient and reproducible.

The new modular Hot Mounting Press Opal X-Press is used to prepare specimens which are easier to handle in the subsequent grinding and polishing process.




Hardness Testing

QNESS is focused on the development and manufacturing of innovative high-end products for hardness testing. In addition to the wide range of versatile standard machines, QNESS is also specialized in the planning and realization of customer-specific solutions.

Hardness testing in powder metallurgy requires completely different parameters and procedures compared to classic hardness testing applications. Samples have to be prepared well to enable the hardness test. Powder has to be embedded in resin, e. g. with a hot mounting press, and afterwards the materialographic specimen has to be polished to obtain a clean surface for hardness testing.

For proving the quality of powder materials a powerful Vickers micro hardness tester like the QNESS Q10/30/60 is the perfect solution.



Debinding, Sintering, Heat Treatment

CARBOLITE GERO manufactures laboratory and industrial furnaces and ovens from 30 °C to 3000 °C.

The company has considerable experience in the heat treatment of MIM parts and is a well-known furnace supplier for additive manufacturing (AM) in the field of powder metallurgy.
For AM applications, the GPC 12/300B Inconel retort furnace has been designed specifically for applications where a modified atmosphere and temperature uniformity are required for the sintering of components from AM machines using metal powders.
The O2 content (which can be less than 30 ppm) can be continually monitored while the shielding gas (nitrogen or argon) is monitored by a digital flowmeter. For AMS 2750E applications the GPC range can meet Class 1.


For MIM applications, CARBOLITE GERO supplies furnaces to debind (catalytically or thermally) and sinter the formed part; this process can either be carried out in two separate furnaces or in a combined furnace (model PDS 120 MO/14).



Elemental Analysis

ELTRA develops combustion analyzers for precise and sensitive CHNOS determination in solids.

The quality control of the metal powders used for powder metallurgical processes is important to ensure a high-quality end product. A typical example is measuring the carbon content in steel, e.g. with ELTRA‘s CS analyzers, as this considerably influences the hardness of the final product.

During the sintering process, unwanted chemical elements like oxygen from air (corrosion) or hydrogen from moisture (hydrogen embrittlement) may degrade the quality of the product so that these should be analyzed, too.




Size Reduction & Particle Size Analysis

RETSCH provides size reduction and sieving equipment designed for sample preparation and characterization of solids.

In the field of powder metallurgy RETSCH instruments contribute to the recycling of raw materials. Sieve shakers like the Vibratory Sieve Shaker AS 200 basic are used to separate those metal powder particles into fractions which are left after the 3D printing process – so that the fraction with the fine particles may be reused for the next printing process.

RETSCH also offers size reduction equipment like the powerful Jaw Crusher BB 500 XL which is suitable for pulverizing incorrect green bodies or hard metal parts produced by Metal Injection Molding. The obtained powder is then returned to the production process.




Particle Characterization

RETSCH Technology manufactures innovative optical measurement systems for particle characterization of powders, granules, and suspensions.

Properties like flowability, compressibility, porosity, or behavior during sintering, which influence the suitability of a metal powder for powder metallurgical processes, depend on the particle size and shape of the powder.

The CAMSIZER X2 system is a powerful dynamic image analyzer covering a size range from 0.8 μm to 8 mm. Two high-resolution cameras capture millions of particle images within a few minutes resulting in unmatched accuracy and reproducibility of the size and shape analysis. What you see is what you get: With more than 300 images per second and a resolution down to 0.8 μm, nothing remains secret.
