Molten Spray Coating TRIZ Cases
- Ferritic Stainless Steel Rebar Coatings for Chloride Corrosion
A thin ferritic stainless steel layer protects conventional rebar from chloride corrosion while fitting high-throughput cold-spray production.
- Plasma Torch Orthogonal Current-Magnetic Flux for Stable Arc Rotation
Orthogonal current and magnetic flux stabilize arc rotation while segmented gas flow protects the powder feed pipe and supports melting.
- Environmental Barrier Coatings With ALD Sealing for CMCs
ALD-deposited oxide sealing layers seal pores and cracks in EBCs, limiting high-temperature steam ingress into CMC substrates.
- Electromagnetic Printer Jetting Mechanism for Fine Droplet Control
Large aluminum droplets cause porosity and uneven surfaces; current pulses and magnetic flux enable controlled fine droplets.
- Metal Matrix Composite Surface Preparation with Plasma and Sol-Gel
Plasma cleaning and a sol-gel adhesion layer prepare metal matrix composite surfaces without exposing fibers, supporting durable bonding.
- Small-Size Inner-Hole Plasma Spraying Gun With Axial Feeding
Axial powder feeding places the outlet in the plasma flame’s high-temperature zone, improving melting and utilization in small inner holes.
- Coated Bodies With Iron-Based Amorphous Alloy Layers Against Crystallization
An iron-based amorphous alloy coating uses spray deposition and B, Si, or C additions to limit crystallization, porosity, and corrosion.
