Overview
The AHT-2010S Advanced Automatic Vickers Hardness Tester is a precision-engineered micro–macro hardness testing system designed for rigorous metallurgical research, quality assurance, and materials development laboratories. Based on the standardized Vickers indentation principle—where a diamond pyramid indenter (136° included angle) is applied under controlled load to produce a geometrically similar impression—the instrument delivers high reproducibility in hardness measurement across a broad load range (1 g to 10 kgf). Its modular architecture integrates electro-mechanical actuation, hydraulic damping, and optical metrology to ensure minimal vibration transmission during indentation, critical for achieving ASTM E384 and ISO 6507-compliant results. The system supports both Vickers (HV) and Knoop (HK) hardness scales, enabling characterization of brittle ceramics, thin coatings, case-hardened layers, and soft metals with equal fidelity.
Key Features
- Sturdy cast-iron frame with reinforced throat clearance (≥120 mm), accommodating large or irregularly shaped specimens up to 100 × 100 mm in XY travel range;
- Motorized Z-axis focusing and specimen positioning driven by a suspended DC motor and vibration-isolated hydraulic system, eliminating mechanical resonance during load application;
- Automated indentation cycle: load application → dwell time (programmable 5–60 s) → unloading → optical image capture;
- Dual-mode illumination: brightfield LED source with adjustable intensity and collimated optics to minimize chromatic aberration and edge diffraction artifacts;
- Three standard objective magnifications (100×, 200×, 400×) with parfocal alignment, supporting both visual inspection and digital image acquisition;
- Integrated load selection mechanism with calibrated dead-weight砝码 sets (1 g–10 kgf); optional 20 kgf upgrade available for macro-scale applications;
- Real-time motor feedback control ensures precise indenter displacement monitoring and repeatability within ±0.5 µm positional accuracy.
Sample Compatibility & Compliance
The AHT-2010S accommodates specimens ranging from polished metallurgical cross-sections (e.g., steel weld zones, aluminum alloy heat-affected areas) to bulk components such as turbine blades, bearing races, and additive-manufactured parts. Its 25 × 25 mm motorized stage provides fine-resolution navigation under optical guidance, while the extended throat design permits direct mounting of oversized fixtures or custom jigs. All hardness calculations comply with ASTM E92 (Vickers), ASTM E384 (microhardness), ISO 6507-1/2/4, and JIS Z2244. Data traceability meets GLP/GMP requirements through audit-trail-enabled software logging, including operator ID, timestamp, load parameters, dwell duration, and raw image metadata.
Software & Data Management
The Windows-based analysis suite includes fully automated image capture, threshold-based impression detection, diagonal length measurement, and HV/HK conversion per ISO 6507-2 Annex A. Features include multi-point grid mapping, statistical reporting (mean, SD, CV%), pass/fail thresholding against specification limits, and export to CSV, PDF, or XML formats. The software supports FDA 21 CFR Part 11 compliance via electronic signatures, role-based access control, and immutable audit logs. Integration with LIMS environments is enabled via TCP/IP or RS232 protocols; optional API support allows bidirectional data exchange with MES or QMS platforms.
Applications
- Case depth profiling of carburized and nitrided steels;
- Mechanical property mapping of functionally graded materials (FGMs);
- Quality verification of brazed joints, thermal spray coatings, and PVD/CVD layers;
- Hardness gradient analysis in welded dissimilar metal assemblies;
- Routine QC testing in aerospace fastener manufacturing and medical implant production;
- Research-grade indentation studies requiring load-dependent hardness behavior (e.g., indentation size effect analysis).
FAQ
What standards does the AHT-2010S conform to for hardness testing?
It complies with ASTM E92, ASTM E384, ISO 6507-1/2/4, and JIS Z2244 for Vickers and Knoop hardness determination.
Can the system perform sequential multi-load testing on a single specimen?
Yes—via programmable test sequences, users can define up to 99 load steps with independent dwell times and measurement protocols.
Is remote calibration verification supported?
Calibration certificates are provided with NIST-traceable reference blocks; optional annual verification services include on-site or lab-return procedures with full uncertainty budget documentation.
Does the software support batch reporting for production lot certification?
Yes—customizable report templates include specimen ID, test location map, statistical summaries, and digital signature fields compliant with AS9100 and IATF 16949 requirements.
What maintenance intervals are recommended for long-term accuracy?
Annual preventive maintenance is advised, including optical alignment verification, load cell recalibration, and hydraulic system fluid replacement per manufacturer specifications.
