It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background section, when a quartz crystal microbalance is used to study atmospheric corrosion of metals, since only one metal can be plated on one quartz crystal, only the corrosion state of the metal plated on the quartz crystal can be characterized, and the corrosion conditions of other metals cannot be characterized, it is impossible to monitor and evaluate the corrosion conditions of products including various metals.
In view of the above, the present application provides a metal corrosion evaluation method, please refer to fig. 1, where fig. 1 is a flowchart of a metal corrosion evaluation method according to an embodiment of the present application, the method includes:
step S101: respectively obtaining electrode metal plated on a quartz crystal, a first corrosion amount and a second corrosion amount of a sample to be evaluated in a preset environment; and the metal with the highest content in the sample to be evaluated is the electrode metal.
The electrode metal is zinc, nickel, copper, silver, iron and aluminum; for example, when the sample to be evaluated is an iron-based sample, the electrode metal is iron, when the sample to be evaluated is an aluminum-based sample, the electrode metal is aluminum, when the sample to be evaluated is a zinc-based alloy sample, the electrode metal is zinc, and so on.
The preset environment includes, but is not limited to, a salt spray environment and a damp-heat environment, and both environments are set according to the GJB150A laboratory environmental test method.
Step S102: and determining the corrosion ratio between the electrode metal and the sample to be evaluated according to the first corrosion amount and the second corrosion amount.
In particular, the method comprises the following steps of,
k＝m1/m2 (1)
wherein k is the etching ratio, m1Is the first etching amount, m2Is the second etching amount.
Step S103: and acquiring a third corrosion amount of the electrode metal in a natural environment, and determining a fourth corrosion amount of the sample to be evaluated in the natural environment according to the third corrosion amount and the corrosion ratio.
The natural environment is the environment where the sample to be evaluated is located, such as a hot and humid marine environment, a warm and humid acid rain environment, a hot and dry desert environment, a plateau low-pressure environment, and the like.
The fourth amount of corrosion of the sample to be evaluated can be obtained from formula (2):
m4＝m3/k (2)
wherein k is the etching ratio, m3Is the third etching amount, m4Is the fourth etching amount.
Optionally, the obtaining a third corrosion amount of the electrode metal in a natural environment includes:
step S201: and acquiring a first frequency of the quartz crystal plated with the electrode metal in a preset environment.
Specifically, the first frequency of the quartz crystal can be measured by a quartz crystal microbalance.
Step S202: and determining a corrosion coefficient in the frequency-to-mass relation according to the first frequency and the first corrosion amount so as to determine the frequency-to-mass relation.
The frequency versus mass relationship can be represented by the general formula:
Δf＝a*Δm (3)
in the formula, Δ f is a frequency change amount of vibration of the quartz crystal, Δ m is a change amount of corrosion mass of the electrode metal, and a is a coefficient.
Setting a fixed sampling time, each time obtaining Δ f1And Δ m1、△f2And Δ m2、△f3And Δ m3、……、△fnAnd Δ mnAnd further obtains the coefficient a in the formula (3).
Step S203: and acquiring a second frequency of the quartz crystal in a natural environment, and determining the third corrosion amount according to the second frequency and the frequency-mass relational expression.
Specifically, the third erosion amount can be calculated by substituting the second frequency into equation (3).
Because the quartz crystal microbalance can realize more precise or more sensitive monitoring and judgment, when the electrode metal corrosion value is slightly changed, the third corrosion amount can be obtained, so that the detection of the micro corrosion of the sample to be evaluated is realized, and the detection is more precise.

it should be noted that, in the present application, the reference sample is not specifically limited, as long as the reference sample and the sample to be evaluated belong to the same class, and there are three types of known corrosion grades, namely, good, medium and poor. The same type means that the reference sample and the sample to be evaluated belong to the same category, for example, when the sample to be evaluated is an aluminum alloy, the reference sample is also an aluminum alloy large sample, further, the three types of the selected aluminum alloy large sample are 7050, 6A02 and 7A04 respectively, and the corresponding corrosion grades are good, medium and poor respectively; when the sample to be evaluated is an iron-based sample, the reference sample can be an alloy steel large-class sample, further, the three types of the alloy steel large-class sample are respectively 1Cr18Ni9, 300M and 40CrA, and the corresponding corrosion grades are respectively good, medium and poor.

It should be noted that the standard corrosion amount can be obtained by measuring a sample with a known corrosion grade in a natural environment, or can be directly selected from stored data of a corrosion test performed before.
Step S303: and determining the preset corrosion grade according to the standard corrosion amount.
And the standard corrosion amounts of the reference samples with different corrosion levels are different, so that the corrosion levels with different good differences and medium differences can be formed, and the corrosion level of the sample to be evaluated is determined according to the size relation between the fourth corrosion amount and the standard corrosion amount.
The metal corrosion evaluation method comprises the steps of obtaining electrode metal, a first corrosion amount and a second corrosion amount of a sample to be evaluated with the highest electrode metal content in a preset environment, determining a corrosion ratio between the electrode metal and the sample to be evaluated according to the first corrosion amount and the second corrosion amount, obtaining a third corrosion amount of the electrode metal in a natural environment, obtaining a fourth corrosion amount of the sample to be evaluated in the natural environment according to the third corrosion amount and the corrosion ratio, determining the corrosion grade of the sample to be evaluated according to the relation between the fourth corrosion amount and the preset corrosion grade, determining the corrosion amount of the sample to be evaluated including multiple metals in the natural environment without measuring the corrosion amount of the sample to be evaluated, determining the corrosion amount of the sample to be evaluated according to the preset corrosion grade relation, evaluating the corrosion grade of the sample to be evaluated, and realizes in-situ real-time monitoring on a sample to be evaluated.
Referring to fig. 2, on the basis of the above embodiment, the metal corrosion evaluation method includes:
step S401: respectively obtaining electrode metal plated on a quartz crystal, a first corrosion amount and a second corrosion amount of a sample to be evaluated in a preset environment; and the metal with the highest content in the sample to be evaluated is the electrode metal.

Step S405: and determining the corrosion accumulation amount of the sample to be evaluated according to the fourth corrosion amount.
And the corrosion is a real-time process, and the fourth corrosion amount at each moment is accumulated to obtain the corrosion accumulation amount.
Step S406: and judging whether the corrosion accumulation amount exceeds a preset corrosion threshold value.
It should be noted that, in the present application, the preset corrosion amount threshold is not specifically limited, as the case may be.
Step S407: and if the corrosion amount exceeds the preset corrosion amount threshold value, sending an alarm instruction to alarm equipment so that the alarm equipment can send alarm information.
The alarm information can be sound alarm information and/or text alarm information.
And if the corrosion amount does not exceed the preset corrosion amount threshold, not processing.
According to the metal corrosion evaluation method, when the corrosion accumulation amount of the sample to be evaluated exceeds the preset corrosion threshold, the limit that the corrosion amount condition of the sample to be evaluated has reached is indicated, and an alarm is given, so that a worker can master the corrosion condition in time.
On the basis of the above embodiment, in an embodiment of the present application, the metal corrosion evaluation method further includes:
determining the corrosion rate of the sample to be evaluated according to the fourth corrosion amount;
judging whether the corrosion rate exceeds a preset corrosion rate threshold value or not;
and if the corrosion rate exceeds the preset corrosion rate threshold value, sending an alarm instruction to alarm equipment so that the alarm equipment can send alarm information.
It should be noted that, in the present application, the predetermined etching rate is not particularly limited, as the case may be.
According to the metal corrosion evaluation method, when the corrosion rate of the sample to be evaluated exceeds the preset corrosion rate threshold value, the limit that the corrosion rate of the sample to be evaluated has reached is indicated, and an alarm is given out to prompt a worker to grasp the corrosion condition in time.

and determining matched test time according to the evaluation time, and determining the thickness of the electrode metal obtained on the quartz crystal according to the test time.
The evaluation time of the sample to be evaluated is set according to the need, for example, the corrosion of the sample to be evaluated needs to be detected for 30 days, 50 days, 90 days, and the like, and correspondingly, the evaluation time is 30 days, 50 days, 90 days, and the like.
If corrosion occurs and the plated electrode metal is not corroded completely, namely the corrosion amount is within an acceptable range, the corrosion amount delta m of the electrode metal can be obtained through a formula (3), so that the corrosion amount of a sample to be evaluated is obtained, and the evaluation of the corrosion grade of the sample to be evaluated is realized; if the corrosion is rapidly increased, the corrosion amount value of the electrode metal exceeds the complete corrosion state of the electrode metal, namely the electrode metal on the quartz crystal is completely corroded, when the corrosion is more serious, the corrosion amount delta m of the electrode metal is always a fixed value, and the change of the delta m cannot be obtained subsequently, so that the corrosion amount of a sample to be evaluated cannot be obtained, and further the corrosion grade of the sample to be evaluated cannot be evaluated. Therefore, the electrode metal with different thicknesses can be selected according to the evaluation time, and detection for 90 days can be realized at most.
