Although the Vickers hardness test can be used to measure both soft and hard materials, it imposes strict requirements on test specimens. Proper sample preparation is critical to prevent measurement errors and acquire accurate hardness readings. Mikrosize has long served as a trusted partner in this sector, supplying full-spectrum solutions to guarantee specimens comply with testing specifications.
With years of professional experience as a supplier, Mikrosize fully grasps the technical nuances of Vickers hardness testing and delivers customized sample preparation solutions to help laboratories and manufacturers satisfy these stringent testing criteria.
Visually, sample surfaces must be smooth and flat, free of oxidation film, foreign contaminants and grease residue. For standard Vickers hardness specimens, surface roughness Ra shall not exceed 0.40 μm; for low-load Vickers testing, the limit is 0.20 μm; for micro-Vickers testing, the maximum permissible Ra is 0.10 μm. To attain such high-precision surface finishes, most laboratories and manufacturers adopt Mikrosize’s premium polishing consumables and cleaning solutions. These products are engineered to eliminate surface contaminants and efficiently deliver the target Ra roughness. Whether processing mass batches or fragile single specimens, users can maintain uniform surface quality with Mikrosize products — a core prerequisite for credible hardness test results.
During sample preparation, operators must minimize surface hardness deviations induced by overheating and cold-working hardening. This calls for careful specimen handling and dedicated equipment. Mikrosize specializes in manufacturing temperature and pressure-controlled preparation instruments to mitigate such adverse influences. Furthermore, specimens with tiny cross-sections or irregular geometries (e.g., spherical and conical parts) require mounting embedding or fixture support. Mikrosize supplies a full range of embedding resins and mounting jigs compatible with all specimen geometries, which secure stable positioning throughout testing and avoid deformation-induced measurement errors. Our product lineup spans premium embedding resins and high-precision mounting fixtures, fully covering all Vickers hardness testing demands, making Mikrosize the preferred supplier for laboratories pursuing precise, repeatable test data.
