Improvement of Wearing Durability of Reed Wire by DLC (Diamond-Like-Carbon) Coating

Abstract

Wearing properties of reed wires used for jet looms were investigated by coating wires with DLC (diamondlike-carbon) in order to improve their wearing durability.
The DLC coated reed wire exceeds 2000 in micro Vickers hardness (Load 50gf (0.49N)).In the accelerated wearing test, the non-coated reed wire showed flaws caused by friction with the yarn only 3 minutes after the test started.On the other hand, a vague flaw was observed 500 minutes after the wearing test started in the reed wire partially coated with DLC at the portion that realized the hardest friction by the yarn.
