Problems solved by technology

However, since only one metal can be plated on a quartz crystal, it can only characterize the corrosion state of the current coating metal, and cannot characterize the corrosion of other metals. Therefore, it is impossible to monitor the corrosion of products including multiple metals Evaluate

Embodiment Construction

[0054] In order to make those skilled in the art better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0055]As mentioned in the background section, when using a quartz crystal microbalance to study atmospheric corrosion of metals, since only one metal can be plated on a quartz crystal, it can only characterize the corrosion state of the current plated metal, and cannot characterize the corrosion of other metals. , therefore, it is impossible to monitor and evaluate the corrosion of products including multiple ...

Abstract

The present application discloses a method for evaluating metal corrosion, which includes obtaining the electrode metal plated on the quartz crystal, the first corrosion amount and the second corrosion amount of the sample to be evaluated in a preset environment; the metal with the highest content in the sample to be evaluated is obtained. is the electrode metal; determine the corrosion ratio between the electrode metal and the sample to be evaluated according to the first corrosion amount and the second corrosion amount; obtain the third corrosion amount of the electrode metal in the natural environment, and determine it according to the third corrosion amount and the corrosion ratio The fourth corrosion amount of the sample to be evaluated in the natural environment; the relationship between the fourth corrosion amount and the preset corrosion level is judged to determine the corrosion level of the sample to be evaluated. The present application realizes that the corrosion amount of the sample to be evaluated does not need to be measured in the natural environment, but the corrosion amount of the sample to be evaluated is determined by the corrosion amount of the electrode metal on the quartz crystal, and then the sample to be evaluated is evaluated according to the preset corrosion grade relationship, In situ real-time monitoring of samples to be evaluated is realized.

Description

technical field [0001] The present application relates to the technical field of metal corrosion testing, and in particular, to a method, device, system and electronic equipment for real-time metal corrosion assessment. Background technique [0002] With the requirements for the use of metal products in all regions, they will face various environments, such as hot and humid marine environment, warm and humid acid rain environment, dry and hot desert environment, plateau low pressure environment, etc., the corrosion situation of metal products in different environments Different, in recent years, the research methods of atmospheric corrosion have made substantial progress. Quartz Crystal Microbalance (QCM) can be used for real-time in-situ monitoring of metal atmospheric corrosion in a very short time. [0003] To study atmospheric corrosion of metals with a quartz crystal microbalance, it is first necessary to evaporate or electroplate the metal to be studied on a quartz waf...
