Surface Finishing Equipment for Aerospace Components

The fundamental mission of aerospace surface finishing equipment is to synthesize a high-integrity, functional boundary layer directly onto structural substrates. This engineered surface imparts critical properties to spacecraft and aircraft components to survive severe orbital and atmospheric environments:

• Anodizing Systems: Widely utilized for lightweight aluminum and aluminum alloy components. By immersing workpieces into precise sulfuric, chromic, or oxalic acid electrolytes under a regulated current density, a robust, integrated aluminum oxide thin film is grown in-situ. This oxide layer fundamentally upgrades the alloy substrate, delivering brilliant surface coloration, excellent dielectric isolation, superior corrosion resistance, and exceptional surface hardness to prevent mechanical friction wear.
• Micro-Arc Oxidation / MAO: Also known as plasma electrolytic oxidation (PEO). This advanced system utilizes plasma chemistry combined with high-voltage electrochemistry to convert the surface of non-ferrous substrates—such as Aluminum (Al), Magnesium (Mg), Titanium (Ti), Niobium (Nb), and Zirconium (Zr)—into high-density, crystalline ceramic coatings with unmatched thermal barrier properties.
• Precision Electroplating: Essential for high-reliability aerospace avionics. Plating ultra-pure gold (Au) and silver (Ag) secures flaw-free electrical contacts and high-frequency circuit traces. Furthermore, electroplated tungsten (W) alloys allow spacecraft components to withstand extreme thermal oxidation and cosmic ray erosion at temperatures exceeding 2000°C, while functional magnetic coatings provide robust electromagnetic shielding (EMI/RFI absorption).
• Thermal Spraying Systems: Utilizes high-temperature heat sources to melt or semi-melt metal alloys, advanced ceramics, cermets, or engineering plastics, propelling them at supersonic velocities onto pre-treated components. This process creates high-thickness barrier coatings engineered for thermal insulation, anti-wear reduction, and high-temperature oxidation resistance across complex rocket and turbine components.
