Reward rules: 3 wealth points for replying, 10 wealth points for a correct answer. This topic is valid for two days; no score will be given if it exceeds two days. Short answer: Why is metal corrosion considered a very complex process? Firstly, the composition, concentration, pressure, temperature, pH value, and so on of environmental media vary greatly. Secondly, the chemical composition, microstructure, and surface condition of metal materials also differ in many ways. Thirdly, different stress conditions can have a significant impact on corrosion damage, and sometimes they even play a decisive role. Therefore, metal corrosion is a very complex process. =============================== 【Mechanical Zone】Recruitment for moderators and technicians – applications and referrals are welcome. 【Valid indefinitely】If you’re interested, come ahead! http://bbs.hcbbs.com/thread-1568748-1-1.html
First of all, the composition, concentration, pressure, temperature, pH value, and so on of environmental media vary greatly； Secondly, the chemical composition, microstructure, surface condition, etc. of metal materials also vary widely ； Again, due to different stress conditions, this can also have a significant impact on corrosion damage, sometimes even a decisive one. Therefore, there are various different methods for classifying corrosion.

Firstly, the composition, concentration, temperature, pressure, pH, and so on of environmental media vary greatly； Secondly, the chemical composition, microstructure, surface condition, and stress conditions of metal materials also vary.
During corrosion, chemical or electrochemical multiphase reactions occur at the metal’s interface, causing the metal to transition into an oxidized (ionic) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, distort the geometric shape of metal components, increase wear between parts, deteriorate physical properties such as electrical and optical characteristics, and shorten the service life of the equipment

Metal corrosion is a highly complex process: the composition, concentration, pressure, temperature, pH value, and other factors of the environmental medium vary greatly； Various aspects such as the chemical composition, microstructure, and surface condition of metal materials ； Due to different stress conditions, this can also have a significant impact on corrosion, sometimes even a decisive one. Therefore, there are various different methods for classifying corrosion.
The chemical changes that occur in metals during corrosion are, in essence, the oxidation of metallic elements to form compounds. Corrosion itself is a highly complex process, and there are many factors that influence it ； During corrosion, chemical or electrochemical multiphase reactions occur at the metal’s interface, causing the metal to transition into an oxidized (ionic) state. It reduces the mechanical properties of metal materials such as strength, plasticity, and toughness.
