The Coatings Shear Fatigue Tester is a specialized laboratory instrument designed to evaluate the durability and adhesion performance of surface coatings under repeated shear stress. It simulates real-world mechanical loading conditions to measure a coating’s resistance to cracking, delamination, and fatigue over time. This tester is widely used in industries such as automotive, aerospace, electronics, and protective coatings to ensure long-term performance, optimize material formulations, and support quality control in production.
Standard
(1)YY/T 0988.13-2017 (China): Specifies shear fatigue testing protocols for coatings on metallic substrates, including load ratios, frequency, and failure criteria.
(2)ASTM F1160-17 (International): Defines methodologies for evaluating the mechanical performance of implant-coating interfaces under cyclic loading.
Product Advantages
(1)Ultra-Precision Loading: Electromagnetic servo motor ensures backlash-free operation with 0.001 N shear force resolution.
(2)Biorelevant Simulation: Integrated 37°C water bath system replicates physiological conditions for in vitro corrosion testing.
(3)Universal Fixturing: Self-centering clamps accommodate substrates (10–50 mm diameter) and coatings (1–200 µm thickness).
(4)High-Cycle Endurance: 10 million cycle capacity with ±0.05% load accuracy.
(5)Compact Design: Benchtop footprint (500 × 450 × 700 mm) suits laboratory environments.
(6)Regulatory Compliance: Pre-loaded YY/T 0988.13 protocols with automated data reporting for FDA/CE submissions.
Product Features
(1)Electromagnetic Servo Actuator: 10 kN shear load capacity with programmable R=0.1–10 ratios.
(2)Dual Sensor System: 0.01 N resolution shear force transducer + 0.001 mm LVDT displacement sensor.
(3)Dynamic Load Control: 0.1–30 Hz frequency range with sine/square/random waveforms.
(4)Thermal-Mechanical Bath: 37±0.5°C recirculating water system with anti-evaporation design.
(5)High-Resolution Imaging: Built-in 5MP camera system for coating delamination analysis.
(6)Safety Suite: Emergency stop, overload clutches, and water leak detection system.
