Description
?
Technical field
The present invention relates to a kind of sampler, particularly a kind of for scraping corrosion product.
?
Background technology
Metal material all inevitably can corrosion in the different usage environment such as atmosphere, ocean, soil, the corrosion of structural metallic material not only causes reduce its serviceable life, cause loss economically, and it also will bring the generation of many mishaies, cause unnecessary casualties.In the safety of use procedure and reliable, must solve the etching problem of metal material in order to ensure product of metal material, the corrosion of material is protected and controlled.So for the metal material surface corrosion control and to protect the required science sample collection that carries out most important.
Chemical action or electrochemical action that metal material is subject to environment occur rotten and destruction, form corrosion product at metal material surface, often the color of the corrosion product of different depth, composition, structure etc. are all variant, and it has reflected differential responses, the mechanism of action that metal material and environment occur to a great extent.For the mensuration of carrying out simultaneously entry, obtain corrosion product profile features and the corrosion mechanism research of metal material in environment, in the gatherer process of corrosion product, hierarchical control sampling tool is of great significance.
In the gatherer process of metal material surface corrosion product, the method that tradition adopts is: use first steel knife (or other sharp weapon instruments) to wipe corrosion product off, then collect the corrosion product of wiping off.Such sampling mode Shortcomings, it is: the corrosion product of wiping off is scattered everywhere, exerts oneself during sampling excessively also can cause wound to parent metal, may increase the risk of material corrosion; The corrosion product of different depth mixes, and can not reflect the corrosion product profile features, may cover the essential reason of corrosion, is unfavorable for designing corrosion control and safeguard procedures and method.
It is blank that the research of metal current material surface corrosion product sampler still belongs to.So the corrosion mechanism of metal material environment is familiar with and corrosion control and the guard technology of metal material from improving, exploitation corrosion product sampler is more accurately controlled sampling depth, carries out stratified sampling and seems extremely important.
