Hot-Dipping/Immersion Processes TRIZ Cases

Vinyl functionalized organopolysiloxane creates a durable, low-friction layer that resolves the conflict between penetration force and coating wear resistance.

A plated steel sheet achieves high tensile strength through precise elemental composition and hot-dip zinc-based alloying.

Segmented plating layers with varying magnesium concentrations suppress liquid metal embrittlement during welding while maintaining corrosion resistance.

Soaking zone dew point management prevents surface silicon concentration, maintaining tensile strength and eliminating pick-up defects.

A Zn-Fe alloy interlayer prevents microcracks in zinc plating during hot stamping, resolving liquid metal embrittlement and maintaining corrosion resistance.

A bimetallic catalyst uses a reduced metal coating to lower activation energy, enabling reactions at lower temperatures and atmospheric pressure.

Heating Al-Mg galvanized steel in low dew point gas before introducing water vapor at reduced pressure achieves uniform blackening without thick coating layers.

Segmented flow regulating members with dispersion holes suppress bottom dross stir-up without requiring sink roll removal.

A tempered coated steel sheet uses a multi-phase microstructure to achieve high tensile strength and elongation.

Optimized alloy composition expands continuous annealing process windows for air-hardenable multiphase steel, ensuring uniform tensile strength and formability.

A galvanized steel sheet employs a dual-layer ferrite microstructure to achieve high tensile strength and formability.

Zirconia and lanthanum oxide surface treatments dissolve aluminum oxide films to restore phosphate treatability and improve coating adhesiveness.

Partial immersion with rotation counters gravity to prevent material wastage and ensure coating uniformity.
