Abstract

The present invention relates to a kind of nickel base superalloy chrome-plated process, using two kinds of electro-active method elder generation anode activations activation of cathode again, the effective passivation layer and dust for removing Surface Creation before nickel base superalloy chromium plating, activate the metal lattice of nickel base superalloy, improve the adhesion of chrome-faced, method is simple and easy to apply, and pollution wastes small.Specific technological process is an electrochemical deoiling → washing → time anode activation → washing → secondary cathode activation → → 50 DEG C of hot water wash → chromium plating of washing.

Description

A kind of nickel base superalloy chrome-plated process
Technical field
The present invention relates to nickel base superalloy chrome-faced technique, closed in high temperature again using after electrochemical acid activating pretreatment Gold surface chromium plating.
Background technology
Nickel base superalloy is due to itself there is stronger self-passivation ability, it is generally difficult to surface electro-deposition is carried out to it, but In reparation or some special occasions, it is necessary to its chrome-faced.Therefore a kind of having in nickel base superalloy electroplating surface is developed Efficacious prescriptions method just has certain realistic meaning, particularly meets aviation reparation, the job requirements of robot industry.
The content of the invention
The technical problems to be solved by the invention are directed to above-mentioned prior art and provide a nickel base superalloy chrome-faced Technique, belongs to a kind of simple and effective, low stain, the nickel base superalloy chrome-faced method of coating performance stabilization.
The present invention the used technical scheme that solves the above problems is：A kind of nickel base superalloy chrome-plated process, including change An oil removing → washing → time anode activation → washing → secondary cathode activation → → 50 DEG C of hot water wash → chromium plating of washing are learned,
Wherein, electrochemical degreasing solution formula and technological parameter：
Anode activation solution formula and technological parameter：
Secondary cathode activated solution is formulated and technological parameter：
Cr-plating Bath is formulated and technological parameter：
Compared with prior art, the advantage of the invention is that：Using two kinds of electro-active methods, (first anode activation again live by negative electrode Change), the passivation layer and dust of Surface Creation before nickel base superalloy chromium plating are effectively removed, activate the metal of nickel base superalloy Lattice, improves the adhesion of chrome-faced, and method is simple and easy to apply, and pollution wastes small.
Specific embodiment
The present invention is described in further detail with reference to embodiments.
The present embodiment nickel base superalloy chrome-faced be using two kinds of electro-active methods effectively remove passivation layer and Dust, for the smooth chromium plating of high-temperature alloy surface provides favourable conditions, improves the adhesion of chromium plating, and method is simple and easy to apply, plating effect It is really good.
Specifically, an electrochemical deoiling → washing → time anode activation → washing → secondary cathode activation → → 50 DEG C of heat of washing Washing → chromium plating,
Wherein, electrochemical degreasing solution formula and technological parameter：
Anode activation solution formula and technological parameter：
Secondary cathode activated solution is formulated and technological parameter：
Cr-plating Bath is formulated and technological parameter：
In addition to the implementation, present invention additionally comprises having other embodiment, all use equivalents or equivalence replacement The technical scheme that mode is formed, all should fall within the scope of the hereto appended claims.
