Tribology Testing (UMT)

Ethos has the capability to perform many tribology tests aided by the UMT (Universal Mechanical Tester), including both dry and lubricated testing types, and even at elevated temperatures. We can perform block-on-ring (BOR), rotating tests (Pin-On-Disk, Pin-On-Side-On-Disk, Ball-On-Disk), reciprocating rotating tests, linear reciprocating tests (Pin, Pin-On-Side, Ball), taber testing, scratch testing, and many other varied types. We can also test a variety of dry and lubricated sample materials, such as metal, organic coatings, polymers, inorganic coatings, metallic coatings, or any other type sample that can be machined to fit testing fixtures for Coefficient of Friction testing, wear, erosion, abrasion, galling, or other surface interaction testing. Ethos boasts a special focus and attention to tribology and wear testing. Ethos maintains membership in the ASTM G02 committee, and has perfected years of innovation and experience in tribology testing on a variety of coupon specimen types.
