Embodiment Construction

[0007] A kind of chemical polishing working liquid of titanium-nickel alloy workpiece, it is characterized in that each raw material and consumption are as follows: every 1000 L liquid contains sodium thiosulfate 8g, the raw material of every 1000 L liquid is hydrofluoric acid 200L, fluosilicic acid 30L, nitric acid 380L, hydrogen peroxide 150L, ​​phosphoric acid 200L and water 40L.

[0008] The production method is carried out according to the following steps: add the calculated and weighed deionized water into the reaction kettle, heat it to 45°C, start the agitator and control the speed at 60 rpm, and then add the calculated and weighed sodium thiosulfate, hydrofluoric acid , Fluosilicic acid, nitric acid, hydrogen peroxide and phosphoric acid were added to the reaction kettle in turn, and stirred while adding until the mixture was uniform. When the temperature of the solution dropped to room temperature, the material was discharged and packaged.

Abstract

The invention discloses a titanium nickel alloy workpiece chemical polishing working solution. 1000L of the titanium nickel alloy workpiece chemical polishing working solution comprises following raw materials, 8g of sodium thiosulfate, 200L of hydrofluoric acid, 30L of fluosilicic acid, 380L of nitric acid, 150L of hydrogen peroxide, 200L of phosphoric acid, and 40L of water. A production method comprises following steps: weighed deionized water is delivered into a reaction vessel, and is heated to 45 DEG C; a stirrer is turned on, and rotating speed is controlled to be 60r / min; weighed sodium thiosulfate, hydrofluoric acid, fluosilicic acid, nitric acid, hydrogen peroxide, and phosphoric acid are delivered into the reaction vessel successively with stirring until uniform mixing is realized; and an obtained solution is cooled to room temperature, and is collected and packaged.

Description

technical field [0001] The invention relates to a chemical polishing fluid for metal workpieces and a production method, in particular to a chemical polishing fluid and a production method for titanium-nickel alloy workpieces with convenient cleaning after polishing, high removal rate and low damage. Background technique [0002] Chemical polishing is a method that uses chemical reagents (polishing fluid) to selectively dissolve the uneven areas of the sample surface to eliminate wear marks and etch leveling. At present, the chemical polishing working fluids applied to titanium-nickel alloy workpieces are basically composed of oxidizing agents, passivating agents, corrosive agents and activating agents. The disadvantage of large damage. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems existing in the prior art, and provides a chemical polishing working liquid and a production method for a titanium-nickel alloy w...
