The invention discloses an electrochemical test method and device based on automatic
coating and a micro-liquid
pool, and relates to the technical fields of
metal corrosion, automatic
coating technology, micro-area
electrochemistry and systematic data accumulation and application. The electrochemical test device comprises an automatic
coating system, a micro-liquid
pool test
system, a test liquidupdating
system, a high-precision XYZ three-dimensional mobile platform, a microscopic
monitoring system, an electrochemical test system, a storage and
control system and a connecting system for controlling effective transmission of control commands and
test data among the systems. The device adopts a
modular design, has high expandability, combines an automatic coating technology with a micro-liquid
pool test system, carries out instant electrochemical sample sealing and measurement on a target research area of a sample under a
microscope, accurately controls the reaction area of a
working electrode, has a high solution amount / reaction
area ratio of the
working electrode, can reduce the influence of reaction products, eliminate
crevice corrosion, and reduce the risks of liquid leakage, blockage and
oxygen diffusion, has lower solution resistance in a test process, and realizes automatic sample sealing and measurement of micro-area
electrochemistry.
