Abstract
The invention discloses a novel 410 stainless steel corrosion solution which is prepared by adding certain amounts of potassium hydroxide, hydrochloric acid and potassium chloride to distilled water, wherein the volume percentage of the potassium hydroxide is 8.5%, the volume percentage of the hydrochloric acid is 17%, the volume percentage of the potassium chloride is 7.5% and the balanced is the distilled water. The potassium chloride is firstly added, the hydrochloric acid is then added and the potassium hydroxide is finally added. The corrosion solution enables metallographic corrosion of the 410 stainless steel to be as easy and quick as that of aluminum alloy. The corrosion solution is saved in cost and is especially suitable for corrosion of the 410 stainless steel.
Description
Technical field
The present invention relates to a kind of novel 410 Corrosion of Stainless Steel solution, belong to etchant solution technical field.
Background technology
410 stainless metallographic structures are difficult to corrosion, even if out it organizes also often show incomplete in corrosion, thus usually all adopt anode overlay film to add polarisation to observe its metallographic.But this observational technique is not only consuming time, and improves cost of manufacture.Therefore how making 410 stainless etching pits become simple and fast the same as aluminium alloy is the difficult problem waiting to solve.
Summary of the invention
The technical problem to be solved in the present invention: provide a kind of novel 410 Corrosion of Stainless Steel solution, 410 stainless steels directly can be observed metallographic structure and not need anode aluminum coated steel and polarisation to observe, to overcome the deficiencies in the prior art after its corrosion.
Technical scheme of the present invention:
A kind of novel 410 Corrosion of Stainless Steel solution, a certain amount of potassium hydroxide, hydrochloric acid and arsenic butter is added in distilled water, with the component of volume fraction be wherein: potassium hydroxide is 8.5%, hydrochloric acid is 17%, arsenic butter is 7.5%, surplus is distilled water, and addition sequence is for first to add arsenic butter, then add hydrochloric acid, finally add potassium hydroxide.
As preferably, described etchant solution adopts conventional solution preparation method to prepare.
When using this corrosive fluid to corrode, corrosion is to micro-yellow.
Beneficial effect of the present invention:
Compared with prior art, 410 Corrosion of Stainless Steel solution of the present invention have following feature:
1. 410 stainless steels through its corrosion after crystal boundary and crystal grain display clear, as long as suitable operation, do not exist tissue corrode incomplete situation;
2. 410 stainless steels are after its corrosion, can be directly used in metallographic structure and observe, and without the need to adopting anode overlay film and Pianguan County to observe, shorten the metallographic sample preparation time greatly; 3. this etchant solution is namely corrodible at normal temperatures, corrodes without the need to being heated to certain temperature again;
In sum, etchant solution of the present invention can make 410 stainless etching pits become simple and quick, and saves cost.
accompanying drawing illustrates:
Fig. 1 is the SEM figure of 100 times of corrosive effects.
embodiment:
Embodiment:
A kind of novel 410 Corrosion of Stainless Steel solution, take mixing acid as raw material, adopt conventional solution preparation method to prepare, in 67mL distilled water, successively add the potassium hydroxide that volume is the arsenic butter of 7.5mL, the hydrochloric acid of 17mL and 8.5mL, then stir with glass stick.The etchant solution made through above-mentioned steps is used for corrosion 410 stainless steel, concrete effect is shown in Fig. 1, and the effect of known etchant solution of the present invention is better.
