High Pressure Accelerated Life Tester
The high pressure accelerated life tester (PCT high-pressure cooking test chamber) is an accelerated aging reliability test equipment simulating severe humid, high-pressure environments. It is widely used to verify the protection performance of electroplated coatings on NdFeB permanent magnets. Under accelerated high-pressure, high-temperature and high-humidity conditions, it quickly validates product sealing reliability and coating corrosion resistance. It serves as core test equipment for magnet reliability verification and weathering R&D of new materials.
Working Principle
A saturated steam environment with high temperature, high pressure and high humidity is created inside the sealed chamber. Coupled effects of pressure, temperature and moisture accelerate water vapor penetration into tiny pinholes and gaps in workpiece coatings. It magnifies corrosion failures that normally take months or even years under natural conditions within a short period. By observing failure modes such as blistering, peeling, rusting and cracking of samples, the coating sealing performance and long-term damp-heat service life are evaluated.
Main Applications
Conduct accelerated damp-heat aging tests on NdFeB magnets with electroplating or epoxy coating to rapidly verify coating compactness and anti-corrosion performance.
Detect hidden defects such as missing plating, pinholes and insufficient coating adhesion, and predict service life under long-term high-temperature and humid working conditions.
Compare anti-aging performance of different electroplating processes and coating schemes, providing test data for surface treatment process optimization and formula improvement.
Meet customer reliability acceptance criteria for product R&D finalization, incoming reliability verification and outgoing quality control.
Perform harsh environmental tolerance verification for high-temperature resistant motor magnets and outdoor-use magnets, evaluating long-term stability in humid and enclosed environments.
