The invention provides a manual cleaning method for a titanium alloy surface, which is characterized in that a portable suit is used for manually cleaning the local surface of a titanium alloy workpiece according to a certain procedure. The suit comprises a polishing material, a wiping material, a sponge dipped with nitric acid, a sponge dipped with deionized water and latex gloves. The method can quickly provide a manual cleaning process meeting requirements for the surface of the titanium alloy workpiece or the rusted surface, is suitable for the condition that the stainless steel passivation process cannot be recovered by adopting a tank liquid immersion mode, removes the pollution on the surface of the titanium alloy workpiece caused by the machining or strengthening treatment process, obtains a pollution-free clean surface, and improves the binding force between the external coating and the titanium alloy workpiece.
Description
Technical Field
The invention relates to a titanium alloy surface cleaning method, in particular to a simple manual titanium alloy surface passivation method which is not provided with a titanium alloy passivation process by adopting a tank liquid immersion mode.
Background
The titanium alloy passivation process is a commonly used surface treatment process for high-precision titanium alloy workpieces, and is used for removing pollutants generated by machining or strengthening treatment on the surfaces of the titanium alloy workpieces to obtain pollution-free clean surfaces and improve the binding force between an external coating and the titanium alloy workpieces.
The titanium alloy passivation process is usually implemented on a fixed special production line, and under the condition that the titanium alloy passivation process cannot be recovered by adopting a tank liquid immersion mode, the passivation process cannot be provided for the surface of a titanium alloy workpiece subjected to mechanical processing or strengthening treatment, so that the cleanliness of the surface of the high-precision titanium alloy workpiece and the binding force between an external coating and the surface of the titanium alloy workpiece are reduced.
Disclosure of Invention
In order to solve the problem, the invention provides a manual cleaning method for the surface of a titanium alloy, which uses a portable suit to manually passivate and clean the passivated local surface of a titanium alloy workpiece according to a certain program.
A manual cleaning method for the surface of titanium alloy features that a portable set of abrasive material, wiping material, sponge dipped in alcohol or other non-halogenated organic solvent, sponge dipped in nitric acid (190-550 g/l), sponge dipped in deionized water, and latex gloves are used to seal them in PVC or acid-resistant plastic bags.
Step 1, cleaning an area needing to be polished by using sponge dipped with alcohol or other non-halogenated organic solvents;
step 2, polishing and cleaning the surface of the titanium alloy workpiece subjected to mechanical processing or strengthening treatment by using a polishing material;
step 3, wiping the polished residues by using a wiping material;
step 4, wearing latex gloves;
step 5, cleaning a polishing area by using sponge dipped with alcohol or other non-halogenated organic solvents;
step 6, after the organic solvent on the surface is completely volatilized, further cleaning the surface by using a sponge dipped with deionized water;
step 7, sticking the sponge dipped with 190-550 g/l of nitric acid on the polished area for 15-60 min, and covering the sponge with plastic; lightly pressing the patch every 10 min;
step 8, wiping the application area by using a sponge dipped with deionized water;
step 9, wiping or sucking the water on the surface by using dried sponge or absorbent cotton or cotton cloth;
step 10, respectively filling the used articles contaminated with nitric acid and other wastes into plastic bags, identifying the articles clearly, and placing the articles as corrosive wastes at specified positions.
The invention has the beneficial effects that: under the condition that the titanium alloy passivation process cannot be recovered by adopting a bath solution immersion mode, the titanium alloy passivation process is rapidly and safely provided for the surfaces of the titanium alloy workpieces subjected to mechanical processing or strengthening treatment, so that the surfaces can obtain pollution-free clean surfaces again, and the bonding force between the external coating and the surfaces of the titanium alloy workpieces is improved.
