1. Introduction
In marine climate and industrial polluted areas, salt spray corrosion serves as a primary cause of failure for metal materials, coatings and electronic parts. Chloride ions contained in salt spray penetrate protective layers and trigger electrochemical corrosion, resulting in rusting, coating peeling, electrical short circuit and other malfunctions, which greatly shorten service life and threaten operational safety. Traditional natural exposure tests feature long cycles and numerous interfering factors, failing to meet the demands of rapid industrial R&D and quality control. By artificially reproducing salt spray atmosphere and accelerating corrosion procedures, Salt Spray Test Chamber efficiently evaluates corrosion resistance and has become indispensable reliability testing equipment in electronics, hardware, coating, home appliance and new energy industries.

LISUN YWX/Q-010 Salt Spray Test Chamber is high-end environmental simulation equipment developed for corrosion resistance inspection. Equipped with precise temperature control, automatic spraying and intelligent monitoring technologies, it supports neutral salt spray (NSS), acid salt spray (AASS) and copper accelerated acetic acid salt spray (CASS) tests and complies with domestic and international standards, satisfying detection requirements of various industries. This paper analyzes the technical application and practical value of Salt Spray Test Chamber based on this equipment.

2. Working Principle and Core Functions of Salt Spray Test Chamber

2.1 Working Principle
Prepared salt solution is atomized into fine particles inside the sealed test chamber via spraying devices to simulate real marine and industrial salt spray conditions. Chloride ions adhere to sample surfaces, penetrate protective coatings and react with internal metal materials electrochemically to speed up corrosion. The anti-corrosion capacity of materials is assessed by observing corrosion status and performance changes of specimens.

2.2 Core Functions
• Accurate environmental simulation: Stably regulate temperature, salt spray sedimentation rate and spraying pressure to restore authentic corrosion conditions.
• Multiple test modes: Compatible with NSS, AASS and CASS tests to fit diverse standard specifications.
• Intelligent monitoring: Automatic sedimentation detection, timing control and alarm functions ensure stable test operation.
• Accelerated performance evaluation: Shorten test period and effectively expose defects of protective layers and structural designs.
