Embodiment 1

[0034] See attached figure 1 , the present embodiment provides a method for depositing a decorative coating on an iron-cobalt soft magnetic alloy, which specifically includes the following steps:

[0035] Step 1: Carry out targeted cleaning on the iron-cobalt soft magnetic alloy. The cleaning process ensures that the iron-cobalt soft magnetic alloy is clean and does not cause corrosion to the iron-cobalt soft magnetic alloy. The specific plan is as follows:

[0036] 1.1: Put the iron-cobalt soft magnetic alloy in the cleaning solution for ultrasonic cleaning. The pH value of the cleaning solution is 7-12 and the temperature is 30-80°C, which can effectively remove the oil on the surface of the iron-cobalt soft magnetic alloy. In order to further improve the degreasing ability of the cleaning agent, the pH value of the cleaning agent is preferably 8.5-10, and the temperature is 40-60°C.

[0037] 1.2: Activate the surface of the iron-cobalt soft magnetic alloy. The activator u...

Embodiment 2

[0056] This embodiment also provides an example of depositing a decorative coating on an iron-cobalt soft magnetic alloy to verify the effectiveness of the method for preparing the decorative coating of the present invention.

[0057] In step 01, the iron-cobalt soft magnetic alloy is ultrasonically cleaned, the pH value is 9, the cleaning agent concentration is 5%, the temperature is 50° C., and the time is 10 minutes.

[0058] Step 02, activating the surface, the concentration of compound weakly acidic activator is 10%, the pH value is 4, the temperature is room temperature, and the time is 3 minutes.

[0059] Step 03, plating nickel on the iron-cobalt soft magnetic alloy for 5 minutes.

[0060] Step 04, plating copper on the iron-cobalt soft magnetic alloy for 25 minutes.

[0061] Step 05, plating nickel on the iron-cobalt soft magnetic alloy for 60 minutes.

[0062] Step 06, plating chrome on the iron-cobalt soft magnetic alloy for 15 minutes.

[0063] Step 07: Ultrason...

Embodiment 3

[0074] The decorative coating deposited on the iron-cobalt soft magnetic alloy is obtained by the above-mentioned embodiment, as the description attached figure 2 As shown, from the surface of the substrate 1 to the outside, it includes a magnetically permeable electroplating layer and a decorative coating, wherein the magnetically permeable electroplating layer is the first water nickel plating layer 2, the water copper plating layer 3, and the second water nickel plating layer from the inside to the outside. Layer 4, water chrome plating layer 5, and the decorative coating layer from the inside to the outside are the vacuum coating layer 6, the vacuum coating functional layer 7 and the vacuum coating color layer 8.

[0075] Wherein, the thickness of the first water-plated nickel layer 2 is 0.41 μm; the thickness of the water-plated copper layer 3 is 2.82 μm; the thickness of the second water-plated nickel layer 4 is 6.83 μm; the thickness of the water-plated chromium layer 5...

Abstract

The invention provides a method for depositing a decorative coating on an iron-cobalt magnetically soft alloy and a product. The method for depositing the decorative coating on the iron-cobalt magnetically soft alloy specifically comprises the following steps of cleaning the iron-cobalt magnetically soft alloy, carrying out electroplating treatment on the iron-cobalt soft magnetic alloy to obtain a magnetic conductive electroplated layer, cleaning the iron-cobalt soft magnetic alloy with the magnetic conductivity electroplated layer, cleaning the iron-cobalt soft magnetic alloy with the magnetic conductive electroplated layer and the electroplated layer in a furnace, and depositing a decorative coating on the magnetic conductive electroplated layer through magnetron sputtering. According to the method, the structure and performance of the magnetic conductive electroplated layer cannot be affected, an oxidation film of the magnetic conductive electroplated layer can be effectively removed through an in-furnace cleaning technology, and the magnetic conductive electroplated layer cannot be damaged. The iron-cobalt magnetically soft alloy deposited with the decorative coating through the preparation method is high in adhesive force and passes a salt spray test (24H), and the saturation flux density of the iron-cobalt magnetically soft alloy cannot be obviously influenced.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to a method for depositing a decorative coating on an iron-cobalt soft magnetic alloy and the iron-cobalt soft magnetic alloy with the decorative coating obtained by the method. Background technique [0002] Iron-cobalt soft magnetic alloy is a kind of iron-cobalt binary or ternary soft magnetic alloy with high saturation magnetic induction intensity. This kind of alloy is widely used in radio electronics industry, precision instrumentation, remote control and automatic control system. It is used in two aspects of energy conversion and information processing, and is an important material in the national economy. [0003] Iron-cobalt soft magnetic alloy is easy to oxidize and rust due to its special material. If the coating is deposited directly by magnetron sputtering, it is prone to failure in the salt spray test. At the same time, it also has poor adhesion and is prone to c...
