Description
Technical field
The invention belongs to pre-etching experimental technique field, more particularly to a kind of pre-etching experiment sample mount.
Background technology
Metal erosion refers to that metal surface and surrounding medium occur chemistry or electrochemical action and make what metal was damaged
Phenomenon, metal erosion phenomenon endangers extremely serious throughout the every field of national economy.
In the actual military service of metal material, corrosion advance damage is relatively conventional, and structural metallic material is subject fatigue
While Cyclic Load, also mutually produce and act on the corrosive medium in environment, most commonly seen is exactly metal material
Corrosion advance damage after fatigue behaviour, and it is this corrosion advance damage after fatigue behaviour can not only consume substantial amounts of metal material
Material, also significantly have impact on the service life during material military service while wasting metals resources, cause equipment premature failure, seriously
When even trigger catastrophic accident and jeopardize personal safety.
During the military service of metal material, etching problem into one of influence fatigue of materials performance it is important because
Element, therefore, assessment material corrosion advance damage after fatigue behaviour become Metal Material Fatigue performance test important content it
One, and rationally the corrosion advance damage of simulation metal material then becomes particularly significant.Under normal conditions, material corrosion advance damage
Fatigue property test is all that the sample that will be processed in advance first carries out accelerating pre-etching experiment, then carries out fatigue property test.And
The corrosion advance damage degree of metal material depends not only on material in itself, additionally depend on the characteristic of corrosive medium, environmental condition and
The relative property of its change, and accelerate the usual way of pre-etching experiment, it is that sample is sufficiently submerged in the corruption configured to laboratory
In the corrosive medium at erosion solution or the scene of taking from, then the corrosiveness for carrying out certain hour.
In pre-etching experiment is accelerated, sample needs to be fully contacted with corrosive medium, and sample generally needs heap to stack
Put, and traditional stacking modes of emplacement can cause sample interval too small, not simply fail to ensure that specimen surface is uniform with corrosive medium
Contact, the test section for also resulting in sample contacts with each other, so as to trigger unnecessary physical damnification.In order to solve to accelerate pre-etching
Sample arranging problem in experiment, technical staff also devises some for the support of sample arranging, but these current branch therewith
Frame more or less still suffers from weak point.
1., the Chinese patent of Publication No. CN2672645, discloses a kind of test sheet shelf, and it is mainly used in salt fog examination
Tryoff, test sheet shelf is connected and composed by support, rotatable test piece placing body and keeper, but the test sheet shelf can be placed
Sample quantities very little, it is impossible to pre-etching experiment is carried out to a large amount of samples.
2., the Chinese patent of Publication No. CN202159008U, discloses a kind of test piece support for corrosion test, its
It is mainly used in the corrosion test of petrochemical plant emphasis corrosion location, the test piece support is by pitman between two ends installing plate, plate
And the shading ring composition on pitman, although can put a fairly large number of sample on test piece support, specimen shape is limited
System, and it is not used to putting for fatigue testing specimen.
3., the Chinese patent of Publication No. CN102954929A, discloses a kind of test-piece support for corrosion test, the test piece
Support is made up of annulus, pole, lacing film bar and nut, and is adopted come the sample of suitable for multiple sizes, but sample by suspended structure
Can cause the fixation of sample very unstable with hang, collision easily be produced between sample, so as to cause sample introduction serious
Physical damnification interference.
