Component for guiding synthetic yarn in melt spinning equipment, has wear-protection layer produced by chemical material conversion of aluminum material and formed by alumina, where wear-protection layer exhibits specific surface hardness

摘要

The component has a wear-protection layer (2) formed at a guiding surface (12) of a guiding body (1) that is made of aluminum material (3). The wear-protection layer is produced by a chemical material conversion of the aluminum material, where surface hardness of the wear-protection layer amounts to 1.800 hardness Vickers 0.025. The wear-protection layer is formed by an alumina, where the depth of the wear-protection layer is increased from 10 to 100 micrometer at the guiding surface of the guiding body. The aluminum material is formed by an aluminum alloy with a portion of a copper.
