Definition: What is chemical corrosion? Chemical corrosion refers to metal loss caused by a pure chemical reaction between a metal and a non-electrolyte, such as the high-temperature oxidation of metals. Or, it is the corrosion that occurs under the action of dry gases or anhydrous organic liquids. ============================ Event Promotion: Petrochemical Zone – “Creative Ideas for Energy Savings” event (the second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Industry Forum) 2017 Coal Chemical Industry Event – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum)
The process in which metal is oxidized and degraded through redox reactions with the substances it comes into contact with
The process in which metal is oxidized and degraded through redox reactions with the substances it comes into contact with
Loss or damage caused by chemical reactions that occur when metals come into contact with dry gases (O2, SO2, H2S, Cl2, etc.)
Chemical corrosion: The process in which a metal is oxidized and degraded as a result of redox reactions occurring directly with the substances it comes into contact with.
The process in which metal is oxidized and degraded through redox reactions with the substances it comes into contact with.
The process of chemical reactions of metals in dry gases and non-electrolyte solutions
The process in which metal is oxidized and degraded through redox reactions with the substances it comes into contact with.
Chemical corrosion is the process in which a metal is oxidized and degraded as a result of direct redox reactions with the substances it comes into contact with.
The process in which metal is oxidized and degraded through redox reactions with the substances it comes into contact with.
Chemical corrosion refers to the direct reaction between a metal and a corrosive medium, with no electric current generated during the reaction process. The forms or characteristics are: (1) Corrosion in dry gases (usually referring to the corrosion of metals under the action of high-temperature dry gases, such as the formation of thick layers of iron oxide during steel rolling, or the corrosion of gas turbine blades while they are in operation) ； (2) Corrosion in non-electrolyte solutions (e.g., corrosion of aluminum in CCl4, CHCl3, or CH3CH2OH, corrosion of magnesium and titanium in CH3OH, etc.).
