Abstract
The invention discloses a novel corrosive solution for 35Cr2MnSiC steel. The preparing method of the novel corrosive solution for the 35Cr2MnSiC steel comprises the step that the components including, by volume fraction, 5.8% of nitric acid, 9.6% of potassium hydroxide and 5.5% of alcohol are added into balance distilled water in the adding sequence that the nitric acid is added firstly, then the potassium hydroxide is added, and the alcohol is added finally. By the adoption of the prepared novel corrosive solution for the 35Cr2MnSiC steel, the metallographic-phase corrosion of the 35Cr2MnSiC steel can be made as easy and rapid as that the aluminum alloy, and cost is saved; the novel corrosive solution can be widely applied to corrosion of the 35Cr2MnSiC steel.
Description
Technical field
The present invention relates to a kind of novel 35Cr2MnSiC steel corrosion solution, belong to etchant solution technical field.
Background technology
The metallographic structure of 35Cr2MnSiC steel is difficult to corrosion, even if out it organizes also often show incomplete in corrosion, thus usually all adopts 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 the etching pit of 35Cr2MnSiC steel 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 35Cr2MnSiC steel corrosion solution, 35Cr2MnSiC steel 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 35Cr2MnSiC steel corrosion solution, it is characterized in that: in distilled water, add a certain amount of nitric acid, potassium hydroxide, alcohol makes etchant solution, with the component of volume fraction be wherein: nitric acid is 5.8%, potassium hydroxide is 9.6%, alcohol is 5.5%, surplus is distilled water, and addition sequence is for first to add nitric acid, add potassium hydroxide again, finally add alcohol.
As preferably, described etchant solution adopts conventional solution preparation method to prepare.
Beneficial effect of the present invention:
Compared with prior art, 35Cr2MnSiC steel corrosion solution of the present invention has following feature:
1. 35Cr2MnSiC steel through its corrosion after crystal boundary and crystal grain display clear, as long as suitable operation, do not exist tissue corrode incomplete situation;
2. 35Cr2MnSiC steel is 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, shortens 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 the etching pit of 35Cr2MnSiC steel become simple and quick, and saves cost.
accompanying drawing illustrates:
Fig. 1 is the SEM figure of 500 times of corrosive effects;
Fig. 2 is the design sketch of general corrosion liquid.
embodiment:
Embodiment:
A kind of novel 35Cr2MnSiC steel corrosion solution, take mixing acid as raw material, adopt conventional solution preparation method to prepare, in 79.1mL distilled water, successively add the hydrofluoric acid that volume is the nitric acid of 5.8mL, the hydrochloric acid of 9.6mL and 5.5mL, then stir with glass stick.
Be used for by the etchant solution made through above-mentioned steps corroding 35Cr2MnSiC steel, concrete effect is shown in Fig. 1 and Fig. 2, and Fig. 2 is the corrosive effect figure using other general corrosion solution, and the effect of known etchant solution of the present invention is better.
