Solid State Diffusion Coating TRIZ Cases
- Composite Steel Part Manufacturing via Segmented Carburizing
A composite steel part manufacturing method uses segmented carburizing and local quenching to form a hardened surface layer on the workpiece.
- NdFeB Magnet Coercivity via Electrostatic Heavy Rare Earth Diffusion
Electrostatic adhesion deposits composite heavy rare earth powders onto NdFeB magnets for high temperature diffusion treatment.
- Surface Activation of Passivated Metals for Low-Temperature Carburising
A heating apparatus decomposes nitrogen and carbon compounds to activate passivated metal surfaces prior to case hardening treatments.
- Martensitic Steel Screw Hardening via Nitriding
Nitriding and quenching boost screw surface hardness while preserving core toughness to prevent hydrogen embrittlement.
- Porous Metal Plate Passivation for Sublimator Contaminant Resistance
Oxidized porous metal plate surfaces treated with short-chain molecules to prevent amphipathic contaminant anchoring.
- Rare Earth Conversion Coating for Aluminum Alloys
A conversion coating composition uses rare earth salts to form a uniform layer on metal substrates.
- Coil Spring Fatigue Resistance via Carburized Layer
Vacuum carburization creates a hardened surface layer on the steel wire, enabling over sixty million fracture-lifetime tests without increasing spring weight.
- Vehicle Component Nitrification via Vacuum Ammonia Decomposition
Adjusting vacuum pressure controls nitrogen potential, accelerating reaction speed and reducing treatment time while maintaining compound layer thickness.
- Low-Pressure Carburizing Steel Cycles
Alternating carbon and neutral gas injections prevent ferrite precipitates and maintain microstructure stability during low-pressure carburizing.
- Chromium Nitride Coated Chain Component Wear Resistance
A diffusion-coated chromium nitride layer with iron and a rough surface improves adhesion and wear resistance on industrial chain components.
- Removable Magnetic Mask for Selective Substrate Coating
Magnetic coupling replaces adhesive tapes to hold the mask securely, preventing lift-off and eliminating chemical removal risks.
- Laser Oxide Layer Formation on Aluminum
Controlled laser intensity and interaction time produce smooth, well-adhering oxide layers while preventing surface burning.
- Electromagnetic Relay Alloy Layer Diffusion Coating
A magnetic component features a diffusion-coated alloy layer on its surface to provide wear and corrosion resistance.
