Description
Technical field
The present invention relates to surface detection technique fields, more particularly to a kind of crizzle detection method.
Background technique
Slag inclusion, micropore, crystal boundary and surface scratching of material internal etc. are likely to crack, these crackles be easy with
The increase of stress and gradually extend, and face crack can cause the performance of equipment, accessory, device sharply to decline, and endanger pole
Greatly, therefore, check that face crack has very important meaning in time.
Currently, osmosis is commonly used for a kind of method of crack nondestructive detection, osmosis is carried out using capillary phenomenon
Flaw detection.Firstly, by the very strong liquid applicator of permeability with fluorescence in substrate surface, because of its strong osmosis, fluorescent liquid
Body will penetrate into bottom along crackle, then wash away the penetrating fluid on surface, and coat display liquid, and since crackle is narrow, capillary is existing
As significant, the penetrating fluid that original penetrates into crackle rises and spreads, and lines is formed in substrate surface, to show the shape of crackle
Shape；This method is although easy to operate, detection sensitivity is high, is also convenient for observing, but detection speed is slower, moreover, because using
Detection agent be strong stimulation toxic chemical, have large effect to the health and environment of people.There is also have use in existing
What microscopy apparatus was detected, Chinese invention patent application specification CN108918549A discloses a kind of wiring board and its detection side
The crack detecting method of method, plated through-hole carries out aging process to board under test first, then, using metallography microscope spectroscopy
Whether the aging plate surface has crackle, using the micro- line in surface of the method detection sample to be tested, although easy to operate, using setting
It is standby few, but because without being handled by dyeing, crackle therein and substrate there is no apparent contrastive colours thus with the naked eye substantially without
Method distinguishes, is also easy to fail to judge, judge by accident even detecting crackle under metallographic microscope.
Summary of the invention
