Problems solved by technology

[0002] The chrome-plated layer has excellent performance and is widely used as the outer layer and functional coating of the protective decorative coating system. With the development of science and technology and people's increasing attention to environmental protection, the surface of existing workpieces after chrome plating has rough surfaces. Poor antifouling performance, low service life, low surface hardness of the workpiece, low adhesion on the metal surface, uniformity of the chromium layer plated on the surface of the workpiece cannot be guaranteed, the production process is cumbersome, and the workpiece needs to be copper-plated or nickel-plated before chrome plating , which increases the cost, the work intensity is high, and the production efficiency is low

Embodiment Construction

[0019] A method for producing an antifouling chrome-plated product, comprising the following steps in sequence:

[0020] a) Wax removal: the surface of the product to be chrome-plated is dewaxed by alkanolamide or fatty acid diethanolamide;

[0021] b) degreasing: the workpiece surface after step a) is processed by a water-based metal oil stain cleaning agent;

[0022] c) Cleaning: placing the processed workpiece in step b) in a water tank for cleaning;

[0023] d) Rust removal: the workpiece after step c) is cleaned by hydrochloric acid for antirust treatment;

[0024] e) Assembling: installing the cleaned workpiece in step d) through the turret for chrome plating;

[0025] f) Surface chrome-plated titanium treatment: The surface of the workpiece assembled in step e) is sprayed with chromium and titanium at the same time through a PVD chrome-plating device. The spraying time is 9-11 minutes. The voltage is 100~150V;

[0026] g) Titanium plating treatment: use PVD chrome p...

Abstract

The invention relates to a production method of a fouling-resistant chrome-plated product. The production method comprises the following steps of wax removal, oil removal, cleaning, rust removal, assembling, chrome and titanium plating treatment on the surface, titanium plating treatment, re-cleaning, drying and examination. The production method has the advantage that through the chrome plating processes such as wax removal, oil removal, cleaning, rust removal, assembling, chrome and titanium plating treatment on the surface, titanium plating treatment, re-cleaning, drying and examination on a workpiece, the workpiece surface forms a fouling-resistant layer so that workpiece fouling-resistant performances and workpiece surface fineness are effectively improved, a copper or nickel plating process on the workpiece before chrome plating is avoided, a production cost is reduced and production efficiency is improved. The PVD chrome-plating device can produce high plasma density and power density and through the PVD chrome-plating device, chrome and titanium can be uniformly distributed on the surface of the workpiece so that chromium and titanium adhesion to the workpiece is improved and the integral hardness is improved.
