Probe-Type Material Surface Wear Scar Tester

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.
