Self-Stabilizing Wear Behavior in HDPE via Untreated Talc Platelets

Assumption under test

Unmodified fillers worsen long-term friction and wear behavior in polyethylene.

Edge of Practice experiment

Mold HDPE containing 10 wt% untreated talc. Subject samples to continuous pin-on-disk sliding over 2–4 weeks while tracking friction coefficient drift.

Failure condition

Increasing friction coefficient or debris accumulation exceeding neat HDPE.

Pass criterion

Stable or decreasing friction coefficient after ≥10⁴ sliding cycles.

Status: Final · Mid-Cycle
