Description
Technical field
A kind of auxiliary tool for corroding metallographic specimen is the utility model is related to, it is specifically a kind of directly to observe metallographic examination
The workbench of sample chemical corrosion process.
Background technology
Chemical attack is display metallographic structure common method, its operation is：The metallographic specimen made is pressed from both sides with clip
Firmly, polishing immerse down in different chemical mordants corrode certain time show tissue topography, according to sample difference and
The difference that tissue display requires, etching time are differed from several seconds to several minutes, and corrosive effect is very big on detection influence, to obtain
The extent of corrosion of the necessary Control Assay of good tissue topography, this just needs sample removing corrosive liquid repeatedly, and overturns sample
To observe the extent of corrosion of burnishing surface.It is disadvantageous in that：By the process that sample is taken out and overturns, burnishing surface will necessarily be caused
The uneven phenomenon of corrosive agent residual, easily produces and corrodes non-uniform problem, influence to detect；This process is also easy to cause at the same time
The drop everywhere of corrosive liquid is spread, test for contamination environment.
The content of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, can be adjusted in time according to observed case
Etching time, so as to the workbench for directly observing metallographic specimen chemical corrosion process of control corrosion rate effect.
In order to reach object above, technical solution is used by the utility model：The one kind directly observes metallographic specimen
The workbench of chemical corrosion process, including support leg and glass panel, four corners of glass panel are fixed with support respectively
Leg, it is characterised in that：The middle part of glass panel is equipped with the surface plate putting hole for placing metallographic specimen corrosion surface plate, glass surface
Two symmetrical location holes are additionally provided with plate, are equipped with adjusting screw rod in location hole, one end of the bottom panel of glass panel is consolidated
Surely two symmetrical positioning seats are equipped with, the upper end both sides of plane mirror are fixed with shaft, and shaft insertion homonymy is adapted
Positioning seat in, in the two sides of plane mirror along the slip draw-in groove for being above respectively equipped with slip, on the side wall of slip draw-in groove fixation set
There is positioning pin, the upper end of adjusting screw rod is connected with nut thread, and the lower end through hole of adjusting screw rod is set on positioning pin.
The beneficial effects of the utility model are：It is simple in structure, easy to use, without sample is taken out simultaneously from corrosive agent
Upset could observe sample extent of corrosion, and due to sample corrosion process whole course visible, be capable of the corrosion of effective Control Assay
Degree, improves corrosive effect, avoids the repetitive operation caused by corrosive effect is bad, improves work efficiency.

Embodiment
The utility model is made with reference to Fig. 1, Fig. 2.A kind of workbench for directly observing metallographic specimen chemical corrosion process,
Including support leg 1 and glass panel 2, four corners of glass panel 2 are fixed with support leg 1 respectively, to meet the steady of entirety
Solidity, it is characterised in that：The middle part of glass panel 2 is equipped with the surface plate putting hole 10 for placing metallographic specimen corrosion surface plate,
Two symmetrical location holes 11 are additionally provided with glass panel 2, adjusting screw rod 6, the bottom of glass panel 2 are equipped with location hole 11
One end of panel is fixed with two symmetrical positioning seats 3, and the upper end both sides of plane mirror 5 are fixed with shaft 4, shaft 4
It is inserted into the positioning seat 3 being adapted of homonymy, in order to 5 angle-adjustable of plane mirror, facilitates operator to observe in surface plate
The corrosion condition of sample, in the two sides of plane mirror 5 along the slip draw-in groove 9 for being above respectively equipped with slip, on the side wall of slip draw-in groove 9
Positioning pin 8 is fixed with, the upper end of adjusting screw rod 6 is threadedly coupled with nut 7, and the lower end through hole of adjusting screw rod 6 is set in positioning
On pin 8.
The thickness of the glass panel 2 is 3-5mm.
The height of four support legs 1 is 15-25cm, to meet the space requirement in operating process.
5 length of plane mirror is less than the height of support leg 1.
During using the utility model, the surface plate for filling corrosive agent is placed in surface plate putting hole 10 first, in order to more
The corrosion condition of good observation metallographic specimen, operator adjust the angle of plane mirror 5 according to the observation angle of itself, turn at the same time
Two nuts 7 are moved, makes adjusting screw rod 6 while rises or falls, since slip draw-in groove 9 can be slided along the edge of plane mirror 5,
It is final plane mirror 54 is rotated around the shaft；The metallographic specimen made is clamped with specimen holder again, burnishing surface is immersed in corrosive agent, it is complete
Into the chemical attack of metallographic specimen.
