Abstract
The decorative plating process of chemical chromium-plated alloy uses chemically plated low-tin bronze or electroplated bright copper-plated layer as bottom layer, and after chemically plating thin tin layer, the plating layer plated by chromium-plated alloy according to the invented "low-temp. chemical chromium-plated alloy plating solution" is silvery, fine in oil gloss, corrosion-resistant, and can be kept bright and non-discoloring for a long period. The invention is a processing technology with high energy saving and environmental protection.
Description
Description
The present invention belongs to the field of chemical plating technology.
The present invention relates to a chemical chromium-plated alloy decorative plating process, and is characterized by that it uses the chemical plating of low-tin bronze or bright copper-plated layer as bottom layer, and uses a chemical plating thin layer tin to plate chromium alloy, and according to the patent "a low-temp. chemical chromium-plated alloy plating solution" the plated layer is silvery, fine in oil-luster, corrosion-resistant and can be kept bright for a long period. The invention is a highly energy-saving and environment-friendly processing technology.
The invention relates to a chemical chromium plating alloy decorative plating process and process conditions, which comprises the following steps:
taking steel parts as an example
1. The oil and rust removal is the same as the electroplating preparation treatment of the steel part.
2. Chemically plating low-tin bronze or adopting a bright electroplated copper layer as a bottom layer.
3. And (5) washing with cold water.
4. And chemically plating a thin layer of tin.
Plating solution proportion and process conditions:
working temperature: above 20 DEG C
Treatment time: not more than one minute
6. According to the patent, chromium-tin alloy is plated in a low-temperature chemical chromium-tin alloy plating solution. The chemical plating time is determined according to the requirements of the workpiece.
7. And (5) washing with cold water.
8. And (5) drying.
Claims (3)
1. The chemical plating chromium-tin alloy decorative plating process is characterized by that it uses the chemical plating low-tin bronze or electroplating bright copper plating layer as bottom layer, and after the chemical plating of thin-layer tin, it is formed according to the procedure of plating chromium-tin alloy in the invented "low-temp. chemical chromium-plating alloy solution".
2. The process of claim 1 wherein said low tin bronze is electroless plated or said low tin bronze is electroless plated after said bright copper layer is plated as a base layer.
3. The process for decorative plating of chemically chromium-plated alloy as claimed in claim 2, wherein after said thin tin layer is chemically plated, said tin alloy is plated in said "a low-temperature chemically chromium-plated alloy plating solution".
