A kind of preparation method of gear electroplating solution, its preparation process are as follows：
Step 1：It is static after stirring after adding sodium sulphate, ammonium bromide and deionized water in chromium trichloride, fill three
Divide mixing, mixed solution A is made；
Step 2：Boric acid, nickel sulfate, citric acid, glycerine, lauryl sodium sulfate, nitrilotriacetic acid are added in mixed solution A
And remaining deionized water, it is then heated to 38 ~ 40 DEG C and stirs, each component is fully dissolved and mixed solution B is made；
Step 3：It will be placed under mixed solution B natures 8 ~ 10 hours and can be made into required electroplating solution.
The beneficial effects of the present invention are：The compounding ingredient of sodium sulphate, citric acid as chromium in the present invention；Nitrilotriacetic acid be with
Position agent, ammonium bromide is as conducting salt, and for boric acid as buffer, glycerine is organic additive；The effect of ammonium bromide is suppression six
The generation of valency chromium and the effusion of chlorine；Reduce the discharge of pernicious gas and the pollution to environment；Total, the present invention has plated film
Stable and uniform, compactness are good, increase the advantages of gear wearability and service life.
