Description
Technical field
This utility model relates to a kind of painting salt uniform at specimen surface, quantitative gas mist for subsequent thermal corrosion testing
Change salt applying appts.
Background technology
Heat erosion refer at high temperature due to environmental factors reaction the deposit that is deposited on material surface with oxygen and
Other corrosive gas acts on down the accelerated corrosion phenomenon to material jointly.Heat erosion effect is at the non-clean ring of high temperature
The military service performance of high-temperature material used under border has the important impact, the hot corrosion resistance of objective evaluation material to be
Parts selection and the basis of safe and reliable use material.
Being coated with salt hot corrosion test is one of important tests method evaluating material hot corrosion resistance.Its process is as follows:
First coat or deposit salt uniformly at specimen surface, then in Muffle furnace, sample is carried out heat erosion under certain atmosphere
Effect, evaluates the hot corrosion resistance of material by the apparent condition and mass change situation observing sample.Test
During, how painting salt amount and the salt distribution uniformity on Control Assay surface is to ensure that test accuracy and repeatability
Key.
The painting salt method that laboratory is conventional at present is spread coating.Spread coating uses brush by certain density saline solution brush
To testing surface, after moisture evaporation, separate out salinity at specimen surface.This kind is coated with salt method can not preferably control examination
The painting salt amount on sample surface and salt distribution uniformity, cause the repeatability being coated with salt hot corrosion test poor.
Summary of the invention
The purpose of this utility model is to provide one and can uniformly be coated with salt at specimen surface and can effectively control to be coated with salt amount
Gas atomization salt applying appts.Technical solution of the present utility model is, gas atomization salt applying appts includes gas
Nozzle, fluid injector, bearing, support, gas passage, fluid path, resistance furnace, heating sample dish and beaker,
Support is arranged on bearing, and bearing is put resistance furnace and beaker, and heating sample dish is placed on resistance furnace, support
Being installed with gas nozzle and fluid injector, gas nozzle and fluid injector on crossbeam is 90 °, and fluid injector is placed in gas
Below body nozzle, fluid injector is connected with fluid path, and fluid path is placed in beaker, and gas nozzle leads to gas
Road connects.
Gas circuit nozzle in device and the orthogonal alignment of heart line of fluid path nozzle, and position is the most adjustable.
This utility model has the advantage that and beneficial effect: this utility model combines the Muffle furnace of certain atmosphere in order to comment
The hot corrosion resistance of valency material.Compressed air flows out through gas nozzle after blood pressure lowering, voltage stabilizing, sprays at liquid
Negative pressuren zone is produced, by saline solution sucking-off and be atomized before mouth.The saline solution of atomization deposits to specimen surface, at resistance furnace
Heat effect under moisture evaporation salt is analyzed thus reach specimen surface be coated with salt effect.Gas circuit in device
Nozzle and fluid path nozzle diameter can independent assortment, the relative position of atomizing pressure, gas nozzle and fluid injector
Adjust, by regulating flow and the atomizing effect of above Parameter adjustable joint saline solution.After determining the flow of saline solution,
The heating power of regulation resistance furnace is matched so that the saline solution depositing to specimen surface can separate out rapidly, keeps away
Exempt from liquid and cause the non-homogeneous precipitation of salinity in the cohesion of specimen surface, thus preferably ensure that salinity is at sample table
The distributing homogeneity in face, and the salt amount that is coated with of sample is ensured by the weightening finish of Control Assay.Atomizer in device
Material uses lucite, and heating sample dish uses zinc-plated corrosion resistant plate, it is to avoid the saline solution corrosion to device feature
Destroy.
Outstanding advantages of the present utility model be can painting salt amount and the salt distribution on preferable Control Assay surface uniform
Property.As it was previously stated, by reasonable combination gas circuit nozzle and the diameter of fluid path nozzle the relative distance regulating the two,
Select suitable atomizing pressure can adjust the flow of saline solution.Therefore, it can use relatively in stage on-test
Bigger flow, thus ensure higher painting salt efficiency, and use less flow in the later stage, thus ensure higher
Painting salt precision.This device uses power controllable resistor stove to heat sample, effectively controls the precipitation of salinity,
The salt avoiding saline solution cohesion to cause analyzes skewness.This assay device is used to carry out being coated with the sample of salt follow-up
Painting salt hot corrosion test in data reappearance good.
