Low-Load Wear Testing Machine

The Low-Load Wear Testing Machine is specifically designed to measure wear behavior under extremely small loads that were previously difficult to evaluate. With a measurable load range starting as low as 0.1 g and extending up to 10 kg, this system enables precise wear analysis of thin films, surface treatments, and delicate materials. A high-speed, low-vibration rotating table ensures stable operation, making the instrument suitable for accurate and reproducible low-load wear testing.

Application

The Low-Load Wear Testing Machine is widely used in applications where ultra-low contact forces and high sensitivity are required, including:

Wear testing of thin films and functional coatings

Evaluation of surface-treated metals and micro-scale surface layers

Tribological testing of polymers, films, and soft materials

Wear behavior analysis of decorative and protective coatings

Research on micro-load friction and wear mechanisms

Typical test samples include:

Thin polymer films

Surface-treated metal sheets

Coated substrates

Functional and decorative coatings
