DARF has an exclusive history with the Peterson Tribology Laboratory to investigate wear of biomaterials using orbital hip simulators. DARF has the capability to run three 12-station hip simulators to analyze biomaterial wear. DARF has experience with reporting gravimetric wear, abrasive wear challenges, and isolating wear debris particles for premarket evaluation and FDA consideration.
