Abstract
The invention discloses a novel ZG18MNCRMORE steel corrosion solution. Picric acid, copper chloride and ethyl alcohol are added into distilled water to form the corrosion solution, 3% of picric acid, 4.5% of copper chloride, 8.5% of ethyl alcohol and the balance distilled water are used according to the volume percent, and the picric acid, the copper chloride and the ethyl alcohol are added in sequence during preparation. After corrosion through the corrosion solution, the grain boundary and the grains of the ZG18MNCRMORE steel are clearly displayed, the corrosion effect is good, the metallographic sample preparation time is greatly shortened, and the corrosion time is short.
Description
technical field:
The present invention relates to a kind of novel ZG18MNCRMORE steel corrosion solution, belong to etchant solution technical field.
background technology:
The metallographic structure of ZG18MNCRMORE steel is 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, also have some common etchant solutions to corrode it, but effect is not clearly simultaneously.Therefore how the etching pit of ZG18MNCRMORE steel becomes simple and fast 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 ZG18MNCRMORE steel corrosion solution, it is clear that the crystal boundary of the ZG18MNCRMORE steel after corrosion and crystal grain show, and corrosive effect is good.
Technical scheme of the present invention:
A kind of novel ZG18MNCRMORE steel corrosion solution, in distilled water, add picric acid, cupric chloride, alcohol makes etchant solution, wherein picric acid, cupric chloride, alcohol are respectively 3%, 4.5%, 8.5% with volume fraction, surplus is distilled water, successively adds picric acid, cupric chloride, alcohol during preparation.
Described etchant solution adopts conventional solution preparation method to prepare.
Beneficial effect of the present invention:
Compared with prior art, after etchant solution corrosion of the present invention, it is clear that the crystal boundary of ZG18MNCRMORE steel and crystal grain show, and corrosive effect is better, shorten the metallographic sample preparation time greatly, and etching time is shorter.
accompanying drawing illustrates:
Fig. 1 is the corrosive effect figure of 100 times.。
embodiment:
Embodiment:
A kind of novel ZG18MNCRMORE steel corrosion solution, in 84ml distilled water, add 3mL picric acid, 4.5mL cupric chloride, 8.5mL alcohol makes etchant solution, successively add picric acid, cupric chloride, alcohol during preparation, then stir with glass stick.
Be used for by the etchant solution made through above-mentioned steps corroding ZG18MNCRMORE steel, concrete effect is shown in Fig. 1, and the effect of known etchant solution of the present invention is better, and it is clear that crystal boundary and crystal grain show.
