Testing Services Available

Wear testing

• Pin on disc testing: various counterparts, wear track diameters 4 to 14mm, load 5 to 100N, speed 10 to 900rpm.
• Reciprocating wear testing: multipass unidirectional or bi-directional wear testing under constant load, various counterpart sizes and materials, load 1 to 200N, speed 5 to 400mm/minute.

Adhesion testing

• Scratch adhesion testing: either single pass scratch test under continuous progressive load or under constant load, Rockwell C diamond, load 5 to 200N, speed 5 to 400mm/minute.
• Rockwell adhesion testing: 0.2mm tip radius Rockwell indentor, 150kg load, to give comparative results from HF1 to HF6.

Coating examination

• Optical microscopy: 50 to 1000x magnification, with image analysis software.
• Scanning electron microscopy

Coating thickness measurement

• Scanning electron microscopy: measurement of cross sections through fractured specimens
• Ball crater method: measurement of taper section through coated samples

Hardness testing
