A fiber or yarn contacted element of a textile machine, such as a rotor of an open-end spinning machine or the like, has, at the fiber or yarn coating surface, a body portion of steel, a boronized layer formed on the body portion, an alpha-iron layer formed on the boronized layer and a nickel coating layer. A process for producing a fiber or yarn contacted element of a textile machine includes boronizing a steel body portion to form a boronized surface thereon, heating the steel body portion in an atmosphere including nitrogen to methanol to produce an alpha-iron layer, quenching and heating the steel body portion and applying a nickel coating thereto.

Process for forming a fiber or yarn contacted element of a textile

A process is provided for producing an open-end spinning rotor assembly. A boron treatment material is applied only to the fiber collecting groove area of the rotor of the spinning rotor assembly. Subsequently, a spinning enhancement material is applied over the boron treated fiber collecting groove and over a sliding wall area of the rotor. An assembly treated with boron treatment material and spinning enhancement material is also provided.
