Product Introduction
Detection range
Applicable materials: Suitable for various metals and alloys such as carbon steel, stainless steel, alloy steel, cast iron, aluminum and aluminum alloys, copper and copper alloys, magnesium and magnesium alloys, titanium alloys, nickel based alloys, as well as metal protective coating materials.
Applicable objects: including metal sheets, rods, pipes, profiles, forgings, castings, industrial equipment components, pipelines, containers, structural components, and various metal product parts.
Applicable environment: Suitable for uniform corrosion testing in various conventional and extreme corrosive environments such as atmospheric environment, fresh water, seawater, soil, acid-base salt solutions, industrial media, high temperature and high pressure media, etc.
Testing purpose: Used for evaluating the uniform corrosion performance of materials, determining corrosion rates, selecting corrosion-resistant materials, controlling product quality, predicting corrosion life, analyzing corrosion failure, and engineering anti-corrosion design.
Testing items
Measurement of uniform corrosion rate: The weight loss method and weight gain method are used to test the corrosion amount per unit area and unit time of the metal in a corrosive environment, and calculate the corrosion rate.
Observation of corrosion morphology: Observe the uniformity and surface state changes of metal surface corrosion to determine whether it is a typical uniform corrosion morphology.
Corrosion product analysis: Analyze the composition, morphology, and distribution of corrosion products to assist in determining the corrosion mechanism.
Performance comparison before and after corrosion: detect changes in metal appearance, size, and mechanical properties before and after corrosion.
Corrosion assessment of media: Evaluate the degree of uniform corrosion of metal materials by different corrosive media.
Corrosion grade assessment: Based on corrosion rate and weight loss, evaluate the uniform corrosion resistance of materials in a graded manner.
