The Probe-Type Material Surface Wear Scar Tester is a precision device designed for high-accuracy measurement of wear scars formed on material surfaces after friction and wear tests. It can automatically measure scar width and depth, calculate wear volume, and display two-dimensional profile maps for intuitive visualization of wear morphology. The instrument quantitatively evaluates material surface wear and abrasion resistance. Additionally, it can function as a step gauge to measure coating thickness and surface profiles, making it widely applicable in material research, coating evaluation, and industrial quality control.

Application

Measurement of wear scars and assessment of abrasion resistance for metals, ceramics, plastics, and composite materials.

Coating thickness measurement and surface profile analysis.

Analysis of wear scars after friction and wear experiments and collection of experimental research data.

Quality control and verification in industrial manufacturing and material inspection processes.

Test Principle

The instrument uses a probe to scan along the wear scar either transversely or longitudinally, measuring scar width and depth while recording wear volume. Minute vertical displacements of the probe are captured with high precision to form a two-dimensional wear scar profile, reflecting material surface wear. The device allows quantitative evaluation of coating or material abrasion resistance and can perform step or profile measurements, providing reliable data for material performance research.

Operation Instructions

Ensure proper connection of power, and that the probe and sample fixture are securely installed.

Select appropriate scanning parameters and measurement ranges based on scar size and depth.

Do not manually touch moving probes or samples during testing to ensure safety.

After the test, save data and generate 2D profile maps and wear volume reports via software.

Regularly inspect the probe for wear and replace as needed to maintain measurement accuracy.

Test Procedure

Sample Installation: Fix the sample onto the sample plate and adjust the fixture to ensure a flat surface.

Parameter Setting: Choose scanning mode, measurement range, and test force.

Start Scanning: The probe automatically moves along the wear scar surface, collecting depth and width data.

Data Acquisition and Display: Generate a 2D wear scar profile in real-time and calculate wear volume.

Result Saving: Save data and generate analysis reports.

Data Analysis: Evaluate material surface abrasion resistance and coating quality based on wear morphology and wear volume.
