Corrosion mechanism and fatigue test
Service Introduction
Corrosion is an ever-present, continuous cumulative process, and often an irreversible process. Economically, corrosion will affect the service life of equipment, cause equipment damage, and also bring other indirect losses; In terms of safety, serious corrosion may lead to casualties. GRGTEST provide Corrosion mechanism and fatigue test services to avoid losses.
Service scope
rail transit, power plant, steel equipment manufacturers, dealers or agents

Service program
Through the corrosion test, it can not only test and evaluate the corrosion performance of the materials and components of the product, but also analyze and study the corrosion phenomenon and corrosion mechanism, so as to provide material selection and improvement and optimization suggestions for the corrosion protection design of the product during use.
● Comprehensive corrosion test: chemical reagent immersion test, composite salt spray test, simulated seawater immersion test, etc.
● Local corrosion test: galvanic corrosion, selective corrosion, stress corrosion, intergranular corrosion.
● coating Study of kinetics and corrosion mechanism of coatings or metal materials.
● electrochemical noise, electrochemical impedance, etc.
