Coating method for DLC (diamond-like carbon) coating on spinning reed and equipment

Abstract

The invention discloses a coating method for a DLC (diamond-like carbon) coating on a spinning reed. The coating method comprises the steps of preparing a metal depletion layer through a vacuum sputter coating or multi-arc ion beam technology and preparing the DLC coating through a vacuum ion coating technology. The invention further discloses equipment capable of applying the coating method. The invention has the outstanding effects as follows: the DLC coating is successfully applied to the spinning reed, so as to solve the problem on surface abrasion resistance of the reed and improve the film rigidity of the reed to HV0.025 2500 to 3500; and the DLC coating has the properties of abrasion resistance, corrosion resistance, high binding force and low friction coefficient, thereby effectively improving the property of the reed, prolonging the service life of the reed, improving the spinning efficiency, saving the spinning cost and ensuring the quality of textile products.

Description

technical field [0001] The invention belongs to the field of metal surface coating, and in particular relates to a DLC coating coating method and equipment applied to textile steel reeds. Background technique [0002] The looms in the weaving workshop are all equipped with reeds, which can be various flat buckles or special-shaped buckles. Its main function is to tighten the weft and determine the warp density of the gray fabric. Textile reed is a consumable product in the textile industry, which has suffered friction damage and fatigue damage. Surface defects of the reed directly affect product quality and textile efficiency. Generally speaking, under the action of warp tension and beating-up resistance, a horizontal wear mark will slowly appear on the reed, which will cause warp breakage in textile technology and affect product quality; and the service life of the reed will be shortened. affect production efficiency. [0003] DLC coating has the advantages of high hardn...

AI Technical Summary

Problems solved by technology

Generally speaking, under the action of warp tension and beating-up resistance, a horizontal wear mark will slowly appear on the reed, which will cause warp breakage in textile technology and affect product quality; and the service life of the reed will be shortened. Affect production efficiency

[0003] DLC coating has the advantages of high hardness, high elastic modulus, beneficial friction and wear properties and good chemical stability, so it is necessary to provide a method to deposit DLC coating on the surface of steel reed by physical vapor deposition (PVD) , to solve the problems of low quality of textile products and frequent downtime for replacement of reeds caused by damaged reeds
