Hot-Dipping/Immersion Processes TRIZ Cases

A sealed reaction chamber circulates oxidizing gas to form a uniform oxide layer, preventing furnace hydrogen from impairing coating adhesion quality.

Decarburized ferrite layer with tempered martensite islands enhances elongation and bendability in plated steel sheets.

Segmented ferrite and martensite phases balance tensile strength with formability while limiting diffusible hydrogen to prevent liquid metal embrittlement.

A galvanized steel sheet with controlled internal oxides maintains platability through precise chemical composition.

A zinc-rich intermediate layer bonds a copper coating to a steel core wire, preventing separation during crimping.

Martensitic hot-dip galvanized steel sheet with controlled carbon distribution gradient prevents hydrogen penetration and delayed fracture at sheared edges.

Adjusting furnace steam partial pressure forms specific oxides to suppress silicon and manganese diffusion, resolving plating gaps.

A precoated metal sheet uses non-oxide ceramic particles within an organic resin to achieve electrical conductivity and corrosion resistance.

Controlled ferrite-bainite microstructure in high-strength steel sheets resolves the trade-off between vehicle weight reduction and impact resistance.

Vapor deposition creates a Zn-Mg-Al alloy layer with a quasicrystalline phase, overcoming hot dip coating limitations to enhance alkali and abrasion resistance.

Superficial oxidation forms a ductile oxide layer on hardenable steel strips, dissipating forming tension to prevent micro-cracks during hot-forming operations.

Optimized ferrite and martensite phase ratios in high-strength steel sheets maintain spot weldability while achieving 780 MPa yield strength.

Ferrite and martensite phase control in steel sheets reduces yield stress variation to improve shape fixability and coatability.

A cold-rolled steel flat product uses controlled alloying to achieve high yield strength and tensile strength.

Segmented cooling stages manage flow velocity to suppress descending gas streams and prevent semilunar wrinkles on thick steel sheets.
