Our team has over 25 years of combined experience in the metallographic preparation of a wide variety of materials. We routinely work with steel samples, components after heat treatment, non-ferrous alloys, superalloys, pure metals, ceramics, composites, as well as coated materials (both thermally and by painting processes). We are also familiar with the preparation of less typical samples such as soil, minerals, coal, or even bone.
Based on our knowledge and experience, we offer a professional service of metallographic sample preparation on demand. Thanks to our well-equipped lab, we handle both single and serial orders — precisely, consistently, and according to the requirements of your analysis.
The standard sample preparation process includes:
Depending on the client’s needs and expectations, we can also perform:
Each order is carried out in accordance with best metallographic practices and agreed process parameters. If needed, we are happy to provide advice and technical support.
Samples are prepared in our laboratory using high-quality consumables and verified procedures. Finished samples are delivered on time — ready for further microscopic analysis, structural testing, or technical documentation. Upon request, we can use client-specified consumables for sample preparation.
Process
Cutting
We perform sample cutting using metallographic cutting machines, adhering to the highest quality standards required in research and industrial laboratories. Depending on the material type, sample shape, and client requirements, the cutting process is carried out using appropriate consumables and clamping systems. Cutting can be performed in either manual or automatic mode.
By selecting the right cutting parameters and consumables, we minimize the risk of overheating, deformation, and structural damage to the material. This ensures optimal conditions for further sample preparation and microstructural analysis.
Mounting – Hot and Cold Methods
Mounting is not always necessary; however, depending on the size, shape, material, and properties of the samples—as well as the requirements of further analysis—some components need to be embedded in resin. When preparing samples for our clients, we offer both hot and cold mounting methods.
We select both the methodology and materials based on the characteristics of the sample and the needs of subsequent testing processes, such as SEM analysis or electropolishing.
Hot mounting is carried out using hydraulic presses, ensuring full control over the process parameters.
Cold mounting can be performed under standard conditions or in vacuum, which is particularly important when full resin penetration of the sample is required.
Vacuum embedding using the right materials also allows for the detection of cracks and voids that may have been present in the part after manufacturing.
Grinding and Mechanical Polishing
The grinding and polishing stage is essential for revealing the material’s structure for further analysis. This structure must be free from artifacts that could interfere with accurate examination. The entire procedure is tailored to each specific project – from initial grinding to final polishing, all materials and process parameters are selected to ensure the best possible results.
Depending on the client’s requirements, the process can be carried out either automatically or manually. We use materials selected based on our extensive experience. Grinding discs, abrasive papers, polishing cloths, as well as diamond and oxide suspensions, are primarily sourced from a single trusted supplier. However, upon request, we can use materials from a specific manufacturer.
This flexibility also allows us to support clients in optimizing workflows in existing laboratories where work must be performed using a designated supplier’s materials.
The developed grinding and polishing method is fully repeatable and provides a surface ready for further analysis.
Electropolishing and Etching
At the client’s request, we can perform sample preparation using an electrolytic polishing and etching unit. This method is particularly useful for materials that are difficult to process or when an exceptionally clean and undistorted surface is required for microstructural analysis.
The process is carried out using carefully selected electrochemical parameters, individually matched to the material type. This ensures high-quality, repeatable results and reliable surface preparation for further examination.
Microscopic Documentation and Macroscopic Measurements
At the client’s request, we prepare a detailed report of the performed work, including microstructure images, coating cross-sections, and an assessment of the presence and characteristics of precipitates, inclusions, and other microstructural features.
Our offer also includes macroscopic measurements of welds, carried out in accordance with technical documentation or specific client requirements. These analyses can complement the evaluation of weld quality and other structural components.
Hardness Testing Services
As part of our service offering, we perform hardness measurements using the Vickers, Brinell, and Rockwell methods—depending on the material type and client requirements. Tests are conducted either on prepared metallographic samples or directly on the surface of the component, provided its geometry allows it.
Measurement results are documented in a report including the applied method, load force, dwell time, and location of the indentation. Upon request, we can also perform hardness profiles across a section (e.g., through the heat-affected zone of a weld) to assess structural changes in the material.
The cost is determined individually after reviewing the client’s requirements and the expected number of samples. The final price depends on the scope of preparation, quantity, analytical services, and the type of consumables used.
Within 48 hours of initial contact and receiving detailed information, we will send you an offer. The completion time is then determined based on the specifics of the project. After all formalities are finalized and your samples are received, we begin the preparation process.
Yes. However, please note that using specific materials may extend the lead time, depending on their availability.
We prepare samples of non-ferrous metals, soft to hard ferrous metals, cemented carbides, ceramics, minerals, and composites.
