Mikrosize's Solutions for Meeting Vickers Hardness Testing Sample Requirements

Although Vickers hardness can measure both soft and hard materials, it has specific requirements for samples. Selecting the right samples is crucial to avoid errors and obtain accurate values, and Mikrosize has long been a trusted partner in this field, offering a comprehensive range of solutions to ensure samples meet the necessary standards. As a professional supplier with years of expertise, Mikrosize understands the intricacies of Vickers hardness testing and provides tailored sample processing solutions that help labs and manufacturers meet these strict requirements.

In terms of appearance, the sample surface must be smooth and flat, without oxide scale, impurities, or oil stains. For ordinary Vickers hardness samples, the surface roughness Ra should not exceed 0.40μm; for low-load ones, it should not exceed 0.20μm; and for micro-Vickers ones, it should not exceed 0.10μm. To achieve such precise surface finishes, many rely on Mikrosize’s advanced polishing tools and cleaning agents, which are specifically designed to remove contaminants and achieve the required Ra values efficiently. Whether dealing with large batches or delicate individual samples, Mikrosize’s products ensure consistent surface quality, a key factor in reliable hardness testing.

During preparation, the impact of factors such as overheating and cold work hardening on surface hardness should be minimized. This requires careful handling and the use of appropriate equipment, and Mikrosize excels in providing instruments that control temperature and pressure during sample preparation, reducing the risk of these detrimental effects. Additionally, samples with small cross-sections or irregular shapes (such as spherical or conical ones) need to be embedded or placed on a platform. Mikrosize offers a variety of embedding materials and platforms that are compatible with different sample types, ensuring stability during testing and preventing distortion that could lead to inaccurate results. From high-quality embedding resins to precision-engineered platforms, Mikrosize’s offerings cater to the diverse needs of Vickers hardness testing, making it a go-to supplier for labs striving for accuracy and consistency.
