Shear Fatigue Resistance Tester for Coatings
Standard
YY/T 0988.13-2017 (China): Specifies shear fatigue testing protocols for coatings on metallic substrates, including load ratios, frequency, and failure criteria.
ASTM F1160-17 (International): Defines methodologies for evaluating the mechanical performance of implant-coating interfaces under cyclic loading.
Product Advantages
Ultra-Precision Loading: Electromagnetic servo motor ensures backlash-free operation with 0.001 N shear force resolution.
Biorelevant Simulation: Integrated 37°C water bath system replicates physiological conditions for in vitro corrosion testing.
Universal Fixturing: Self-centering clamps accommodate substrates (10–50 mm diameter) and coatings (1–200 µm thickness).
High-Cycle Endurance: 10 million cycle capacity with ±0.05% load accuracy.
Compact Design: Benchtop footprint (500 × 450 × 700 mm) suits laboratory environments.
Regulatory Compliance: Pre-loaded YY/T 0988.13 protocols with automated data reporting for FDA/CE submissions.
Product Features
Electromagnetic Servo Actuator: 10 kN shear load capacity with programmable R=0.1–10 ratios.
Dual Sensor System: 0.01 N resolution shear force transducer + 0.001 mm LVDT displacement sensor.
Dynamic Load Control: 0.1–30 Hz frequency range with sine/square/random waveforms.
Thermal-Mechanical Bath: 37±0.5°C recirculating water system with anti-evaporation design.
High-Resolution Imaging: Built-in 5MP camera system for coating delamination analysis.
Safety Suite: Emergency stop, overload clutches, and water leak detection system.
