In the aerospace industry, the reliability of mechanical components is of fundamental importance. The washing and surface treatment processes are highly critical and controlled. Washing must remove oils, particulates, and contaminants using water-based washing systems, spray or immersion, specific solvents, ultrasound, or high-pressure spraying systems. Thorough cleaning must be guaranteed without compromising tolerances. Surface treatments must also guarantee protection and improve the performance of metals by increasing resistance to corrosion and wear. Advanced coatings, such as PVD, provide superior functional properties. The combination of targeted washing and protective treatments is essential to meet the stringent safety, durability, and performance standards typical of the aerospace industry.
