The Micro-Scale Abrasion Tester is a precision instrument specifically designed to evaluate the wear resistance of materials under micron-scale abrasion conditions. It is particularly suitable for studying the micro-abrasive wear behavior of hard and soft coatings, metals, polymers, sealing elastomers, and other advanced materials. Its major technical features are as follows:
Core Technical Features
Micro-scale wear simulation
The system can simulate surface wear caused by tiny hard particles, such as debris present in lubricants under real operating conditions. It is especially suitable for wear-sensitive materials including dynamic seals, coatings, and elastomers.
High-precision load control
The loading range is typically from 0.05 N to 5 N, while some models support milli-Newton-level precision loading. This enables accurate application of normal force and ensures excellent test repeatability and reliability.
Controllable sliding speed
The rotational speed of the ball or specimen is generally adjustable within a range of 30–150 rpm, allowing simulation of wear behavior under different relative motion conditions.
Standardized testing configuration
The equipment commonly adopts a Ball-on-Plate contact configuration and complies with relevant ASTM wear testing standards, ensuring consistency and comparability of results.

Certain models can also be used for coating thickness measurement by generating controlled wear craters, enabling non-destructive thickness evaluation of thin coatings and surface films.
The Micro-Scale Abrasion Tester is a precision instrument used to evaluate the micro-scale wear resistance of materials. It is particularly suitable for studying the micro-abrasive wear behavior of sealing elastomers such as rubber and polymers under realistic operating conditions.
The core principle of this tester is based on a controllable micro-scale friction and wear process. By simulating localized scratching and material removal caused by hard micro-particles under lubricated conditions, the system quantitatively evaluates the micro-abrasion characteristics of materials.
Key Testing Principles
Friction mode
The tester adopts linear or rotational sliding contact, allowing relative motion between the specimen and abrasive particles (such as silicon carbide or aluminum oxide particles) or between the specimen and a counterface material.
Load control
Precisely controlled low loads—typically ranging from several milli-Newtons to several Newtons—are applied to simulate the actual forces generated by micro-abrasive particles in service environments.
Wear mechanism
The primary wear mechanism involved is three-body abrasion, where hard particles are trapped between two contacting surfaces. This interaction may lead to:
Micro-crack formation
Plastic deformation
Micro-cutting and material removal on the specimen surface
Wear Measurement Methods
Optical profilometry
An optical profilometer is used to measure the volume and three-dimensional morphology of the wear scar generated during testing.
Mass loss measurement
A high-precision electronic balance can be used to determine material mass loss. Combined with the material density, the wear volume can then be calculated quantitatively.
The Micro-Scale Abrasion Tester is used to evaluate the wear resistance of materials under micro-abrasive wear conditions. It is widely applied in research fields involving coatings, biomaterials, metal alloys, polymers, and advanced engineering materials.
