Industry Background
Aerospace-grade aluminum alloys, titanium alloys and precision mating surfaces (including valve bodies, connectors and inner walls of actuators) demand ultra-high surface quality. Even microscopic corrosion or residual contaminants may cause assembly tolerance deviation, seal failure and even flight safety hazards.
Industry Challenges
1.Micro-corrosion on precision mating surfaces
Slight rust invisible to the naked eye will alter dimensional tolerances and surface roughness of mating surfaces, failing to meet designed interference fit and sealing requirements during assembly.
2.Residue contamination from traditional anti-rust media
Residues of anti-rust oil and grease are difficult to remove completely, which impairs the adhesion and uniformity of subsequent surface treatments including anodizing, electroless plating and spraying.
3.Pitting corrosion induced by extreme temperature cycling
Aerospace components are transported across a wide temperature range from polar low temperatures to equatorial high temperatures. Repeated condensation causes pitting on aluminum and titanium alloys, which further develops into fatigue crack sources.
4.Strict cleanliness and packaging regulations
The aerospace industry requires packaging materials to be free of silicon, sulfur, chlorine and gaseous pollutants, which traditional anti-rust products cannot satisfy comprehensively.
VCI Solution Value Proposition
Our residue-free and pollution-free vapor anti-rust solution maintains a stable protective layer under extreme temperature fluctuations, enabling delivered parts to be directly assembled.
