Metallic Material Coating Processes TRIZ Cases
- Zirconium Niobium Cemented Carbide Sintering
Vacuum sintering a powder mixture with zirconium and niobium carbides reduces porosity while maintaining strength.
- Fuel Cell Separator Plate Wettability Modification
Hydrogen peroxide and silane treatments modify separator plate wettability, reducing water blockages and ohmic losses in fuel cells.
- Zr/Ti Pretreatment for Corrosion Protection
A multi-stage acidic pretreatment deposits zirconium or titanium conversion layers on metallic components to enhance corrosion resistance and paint adhesion.
- Surfactant-Free Sol-Gel Synthesis of Light-Selective Particles
A surfactant-free sol-gel method synthesizes light-selective particles using aqueous precursors.
- Ceramic Coated Steel Tubes for Heat Recovery Units
A ceramic coating on steel tubes prevents ash adhesion, reducing maintenance costs while maintaining thermal transfer efficiency.
- Carbon Steel Passivation for Nuclear Reactor Recontamination
Reusing chelating agents creates a protective film that reduces radioactive contamination and secondary liquid waste in nuclear systems.
- Acidic Conversion Coating for Metal Surfaces
An acidic aqueous conversion composition deposits a protective layer on metal surfaces using fluoride and zinc ions.
- Wet Atomic Layer Etching of Noble Metals via Segmented Passivation
A wet atomic layer etching process uses sequential chemical modification and dissolution steps to precisely remove noble metal surfaces.
- Sulfate Coating for Steel Forming Friction Reduction
Aqueous sulfate coating reduces friction during cold steel forming.
- Austenitic Alloy Fe-Cr-Ni-W Film Molten Salt Corrosion
Fe-Cr-Ni-W oxide film protects austenitic alloy surfaces, preventing ion diffusion and corrosion at 600°C.
- Tellurium-Based Metal Surface Treatment for Gray Coloring
A tellurium-containing solution colors metal surfaces directly into a grayish tone without oxide film formation.
- Wear Protection Coating Using Biodegradable Binders
A wear protection coating method applies hard particles suspended in a water-based binder mixture to a substrate surface.
