Abrasion and Wear Test

Abrasion and wear testing is performed to evaluate the resistance against to scratching abrasion of solid materials including metals, ceramics, composites, weld overlays and thermal spray coatings.

STEMart provides various abrasion and wear testing to rank materials or coatings in their resistance to scratching abrasion under different conditions.

Standard Tests

• Pin abrasion testing: Two pin specimens-the test material and a reference material. Each pin, in turn, is positioned perpendicular to the abrasive surface, which usually is mounted on, or supported by, a flat circular disk, another flat surface, or the cylindrical surface of a drum. The test machine permits relative motion between the abrasive surface and the pin surface.
  • Pin-on-disk abrasion testing
  • Pin-on-drum abrasion testing
  • Pin-on-table abrasion testing
  • Pin-on-belt abrasion testing
• Taber abrasion testing: Mount a flat square or round specimen in a thickness of 0.25” to a turntable platform that contracts two abrasive wheels which rotate over the specimen at a fixed speed and pressure to provide contact wear.
• Fall sand/silicon carbide abrasion testing: Apply the organic coating to a plane rigid surface, such as a metal or glass panel. Abrasive falls from a specified height through a guide tube onto the coated panel until the substrate becomes visible.
• Rubber wheel abrasion testing: Load a rectangular test sample against a rotating rubber wheel and deposit sand of controlled grit size, composition, and flow rate between them.
• RCA abrasion testing: Evaluate the effect of repeated abrasive forces on painted or plated organic finishes, foil, and inks or coatings on printed membrane switches.
• Block on ring abrasion testing: Evaluate the sliding wear behaviors of mate-rials in different simulated conditions, allow reliable ranking of material couples for specific tribological applications.
