Coating material mechanics properties testing and micromechanism of damage are probed into the related technology and tested mostly using universal tensile
Machine carries out under macro-scale, generallys use the tension crack process of the method observation coating of high resolution camera shooting, and ties
Close the strain variation situation of Digital Image Correlation Method measurement coating front surface.
It needs to make tensile sample matrix under normal conditions, coating material to be tested is then sprayed on basis material, it
Typical spray speckle is carried out to coating material surface afterwards, it is therefore an objective to calculate strain for subsequent digital image correlation method and mark is provided
Point.Tension test is carried out to tensile sample using universal tensile testing machine after being ready to complete, needs to utilize height in experimentation
Resolution camera records drawing process to observe the detailed process of coating cracking, and serialograph, so as to utilize number
The strain variation situation of word DIC Method calculating coating front surface.
The changing rule of speckle during stretching is calculated using digital picture related algorithm, obtains strain stress relation.It will apply
Layer material is broadly divided into 4 stages to face crack cracking in receiving tensile load:
(1) when coating just starts to bear tensile load, irregular variation is presented in strain;
(2) with the increase of tensile load, coating surface strain is orderly fluctuation status, is similar to sine curve, maximum
Strain is respectively wave crest and trough with minimum strain, and wave crest and trough are constantly mobile to same direction;
(3) when tensile load reaches certain phase, the fraction areal strain of coating is sharply increased;
(4) it when the strain of the coating area sharply increased reaches capacity, i.e., the stress in region reaches ultimate tensile, applies
Layer is broken.
But since coating is too thin, this method can only detect coating surface strain variation and crack propagation, can not observe
The changing rule extended to the lateral position Interface Crack and face crack of coating to Interface Crack.
The observing interface crackle and face crack generallyd use to the method that Interface Crack extends be by controlling omnipotent examination
Test the load gradual change realization of machine.Such as prepare the identical multiple matrix of samples for being coated with coating material of parameter, respectively with gradually
Increased constantly acting load tensile sample matrix stops stretching, sample is removed tensile sample when stretching reaches determined load
Section metallographic specimen is made, observed under a scanning electron microscope to determine crackle form in drawing process and crackle transformation
Process.But this method can not real time reaction crackle expansion process, and the selection of load range have it is certain random
Property, cause resulting crackle discontinuous with tensile load changing rule, the accuracy of crack propagation process may be will affect.In addition
It is lack of standardization due to grinding and polishing in the preparation process of observation sample, it is likely to result in cracked inside brittle coating, influences to tie
The accuracy of fruit observation.
In view of the status of the relevant technologies coating material tension test observed pattern, embodiment according to the present invention is proposed

Image carries out overall process video recording.The computer system respectively with 100 phase of the scanning electron microscope and original position stretching machine
Even, picture is handled using loading by means of digital image correlation method to obtain the strain size and its change procedure on coating material surface.
Coating material original position stretching observation system 1 according to an embodiment of the present invention can be placed in scanning electricity by setting
Original position stretching machine 100 in the microscopical sample bin 400 of son, so as to utilize the scanning electron microscope to drawing process
It is observed, realizes the dehiscence process from micro-nano rank observation coating, can clearly capture the specific of coating cracking
Process, the position including crack initiation, the path of crack propagation and speed etc..Furthermore with scanning electron microscope in Gao Fang great
In-situ observation is carried out under multiple, can observe the variation of coating material microscopic appearance, facilitates the mechanism for analyzing coating cracking.
It for example, during stretching can be with synchronous recording displacement/load signal, so as to realize to coating material
The analysis of mechanical property;And the change procedure of coating material can be recorded, under micro-nano-scale so as to infer coating
Micromechanism of damage of material during stretching/compressing;A label is identified on coating surface to be observed with nano-imprinting method
Later, the image shot during stretching experiment using loading by means of digital image correlation method processing scanning electron microscope, can obtain
Obtain the strain size and local train change procedure of coating surface.
