Description
Technical field
The invention belongs to metallographic sample preparation and field of display technology more particularly to a kind of iron-based zinc coat or zinc coat are color
The color method of coloured gold phase.
Background technique
The various performances of microstructure and metal material inside metal material have it is direct and close contact, benefit
Observation, which is carried out, with microscopic structure of the metallographic microscope to metal material is presently the most a kind of convenient, fast and effective mode.
Metallographic refers to the physical state and chemical state of the chemical component and various composition of metal or alloy inside alloy.Pass through gold
The reason of facies analysis can be assessed and be prejudged to the performance of material, while metallographic can be used for material failure and destroy
Analysis.
At present metallographic field be most widely black and white metallographic, black and white metallographic speculate it is not high etc. due to more
Mutually and infiltration, the distinguishing ability of coating are limited.Colour metallograpy speculates variation of the very high formation for cutting inteferometer coating to material composition
Value that is very sensitive, therefore having its irreplaceable in colour metallograpy production practices.
Zinc has that good corrosion resistance, fusing point are low, are easy to coat and the features such as " sacrifice " anode electrochemical protective effect, therefore
Zincizing, zincincation are to be applied to widest method in coating protection materials at present.
In conclusion problem of the existing technology is:
Zincizing at present, zinc-plated metallographic specimen mainly use 4% nitric acid alcohol to be corroded, in Display of Grain Boundary clarity
Upper, phase region divides on significant degree, speculates in display and there is poor phenomenon in result precision, and colour metallograpy currently not yet
Dye technology is in zincizing, zinc-plated metallographic structure successful story.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of iron-based zinc coat or zinc coat colour metallograpy
Color method.
The invention is realized in this way the color method of a kind of iron-based zinc coat or zinc coat colour metallograpy, including it is following
Step:
Polishing: successively polishing to iron-based zincizing or galvanizing sample using the abrasive paper for metallograph of different size, and every one dozen
To ensure specimen surface scratch in the process of the sand paper of mill in one direction and be evenly distributed, and be rinsed with water completely, will try
One of polishing operation is carried out down again after sample rotation；
Polishing: it by iron-based zincizing or galvanizing sample after grinding process, holds and is polished on polishing machine；
Pre- etch: by after polishing iron-based zincizing or galvanizing sample immerse in pre- etching solution 10 seconds~45 seconds, etch is completed
It is rinsed, ethyl alcohol cleaning, then dried up with flowing water afterwards；
Coloring: it will be put into coloring liquid by the iron-based zincizing of pre- etch or galvanizing sample, and colour 30 seconds~60 seconds, then use
Dehydrated alcohol is rinsed well and is air-dried with hair dryer.
Further, in the polishing step, successively using the abrasive paper for metallograph of 400#, 600#, 800# to iron-based zincizing or plating
Zinc sample is polished；One of polishing operation is carried out down after sample is rotated by 90 ° again.
Further, in polishing step, antiscuffing paste is coated on polishing cloth before polishing and smears smooth, hand guarantor in polishing process
Maintain an equal level steady and is continuously added clear water；Wherein polishing cloth is canvas, and antiscuffing paste is the diamond polishing cream that granularity is W2.5.
Further, in pre- etch step, pre- etching solution is dissolved in obtained by dehydrated alcohol by nitric acid, and volume ratio is 4 nitric acid: 96
Dehydrated alcohol.
Further, in tinting steps, the solution that coloring liquid is made of sodium molybdate, sulfamic acid, distilled water, mass ratio is
0.8g~2.3g sodium molybdate: 0.4g~1.7g sulfamic acid: 50g~130g distilled water.
Another object of the present invention is to provide a kind of colorings using above-mentioned iron-based zinc coat or zinc coat colour metallograpy
The zinc-plated common carbon structural steel of method coloring.
Advantages of the present invention and good effect are as follows: the coloring of iron-based zinc coat provided by the invention or zinc coat colour metallograpy
Method, iron-based (infiltration) zinc coat colour metallograpy crystal boundary complete display speculate display height, even without polarised light and sensitive tint
Clearly microscopic structure can be obtained, different phase and its distribution can be obviously differentiated.Step of the present invention is simple, reproducible, coloring
Effect is good and stability is good, and the preparation of sample carries out at room temperature, and the sample prepared can be protected for a long time at normal temperature
It deposits.
