Abstract
The invention provides a ceramic anodized tank fluid formula, in particular to an improvement to the ceramic anodized tank fluid formula, which belongs to the surface treatment technique. The ceramic anodized tank fluid formula is characterized in that the components of the tank fluid formula comprise chromic anhydride with the content of 20 to 50 grams per liter, boric acid with the content of 0.5 to 3 grams per liter, and titanium potassium oxalate with the content of 10 to 20 percent of the content of the chromic anhydride, balance water. The anodized film layer is provided with the gloss of porcelain glaze and porcelain enamel, and the hardness and the reliability of the working component under the wearing condition are reliable. Experiments prove that the hardness is improved by more than 30 percent, and the wear resistance is enhanced by more than 40 percent.
Description
Technical field
The invention belongs to process for treating surface, relate to improvement electrochemical enamelizing tank liquor prescription.
Background technology
Need to carry out electrochemical enamelizing in many aluminum alloy part manufacturing processedes of aircraft engine.Existing electrochemical enamelizing tank liquor prescription is: chromic anhydride content: 20～50 grams per liters; Boric acid content: 0.5～3 grams per liter; Surplus is a water.Its shortcoming is: the anodizing rete that is produced does not have enamel and enamelled gloss; Hardness is low; Wear no resistance.
Summary of the invention
The objective of the invention is: propose a kind of electrochemical enamelizing tank liquor prescription that can improve film quality,, improve the reliability of working part under hardness and the state of wear so that the anodizing rete that is produced has enamel and enamelled gloss.
Technical scheme of the present invention is: a kind of tank liquor prescription of electrochemical enamelizing is characterized in that the composition of tank liquor prescription is as follows: chromic anhydride: content is 20～50 grams per liters; Boric acid: content is 0.5～3 grams per liter; Titanium potassium oxalate(T.P.O.): content is 10%～20% of chromic anhydride content; Surplus is a water.
Advantage of the present invention is: the anodizing rete that is produced has enamel and enamelled gloss, has improved the reliability of working part under hardness and the state of wear.Evidence, hardness have improved more than 30%, and wear resisting property improves more than 40%.
Embodiment
Below the present invention is described in further details.A kind of tank liquor prescription of electrochemical enamelizing is characterized in that, the composition of tank liquor prescription is as follows: chromic anhydride: content is 20～50 grams per liters; Boric acid: content is 0.5～3 grams per liter; Titanium potassium oxalate(T.P.O.): content is 10%～20% of chromic anhydride content; Surplus is a water.
When carrying out electrochemical enamelizing, the boost in voltage curve that is adopted is identical with original technology, and be specially: voltage rises to 40 volts by 0 volt in 5 minutes, keeps 30 minutes, rises to 60 volts then in 5 minutes, keeps outage in 30 minutes.Tank liquor temperature remains on 45 ℃～55 ℃.
The reason that the present invention improves anodizing rete quality is: titanium potassium oxalate(T.P.O.) is in solution during anodic oxidation, not only oxalate denominationby enters rete, and titaniferous (by aluminium reducing), titanyl compound are also arranged in the fenestra, has changed the rete composition, improve solidity to corrosion, improved outward appearance.
Embodiment.Following table is the comparative test result of tank liquor of the present invention and existing tank liquor, and first group is existing tank liquor, and second group is tank liquor of the present invention, and processing parameter is identical during processing.Evidence, the microhardness of the anodizing rete that tank liquor of the present invention is handled improves more than 30%, and wear resisting property improves more than 40%.
