Subway systems worldwide rely heavily on electronic signaling components to ensure safe, reliable, and timely train operations. These components are exposed to harsh environmental conditions, such as moisture, temperature fluctuations, and airborne contaminants. For this reason, corrosion protection for electronic components in rail systems has become essential to maintaining performance and preventing costly failures. The

Degreasing metal parts is a critical step in most manufacturing and maintenance workflows. However, while removing oils and residues, many conventional degreasers expose metal surfaces to oxygen and moisture, creating the perfect environment for flash rust. This form of immediate surface corrosion can occur within minutes of rinsing and can compromise part quality, downstream coatings,
