Molten Spray Coating TRIZ Cases
- Yttria Polycrystalline Coating for Plasma Chamber Particle Control
Aerosol deposited yttria polycrystalline layer reduces particle detachment from quartz glass surfaces during semiconductor manufacturing.
- Foam-like Coating for Ceramic Blade Stress Distribution
Porous foam-like coatings absorb mechanical loads at ceramic blade interfaces, reducing stress concentrations that cause cracking.
- Engine Block Coating System Using Gas Shielding
Gas nozzles shield opposing cylinder bores from coating spray, eliminating masking materials and reducing manufacturing costs.
- Chrome-Free Plastic Pretreatment Using Nitric and Sulfuric Acid with Periodate Ions
A chrome-free pretreatment process modifies plastic surfaces using nitric acid, sulfuric acid, and periodate ions to create high adhesion bonds for metal coatings.
- Water Soluble Plug for Cooling Hole Protection During Coating
A water insoluble core with a dissolvable outer layer protects holes during thermal spraying.
- Airfoil Cluster Coating via Segmentation and Diffusion Brazing
Wire EDM segmentation allows complete coating coverage on inaccessible airfoil surfaces while diffusion brazing restores structural integrity.
- Thermal Barrier Coating Adhesion via Vertical Cracks
Vertically oriented cracks in the coating microstructure relieve thermal expansion strain, eliminating the need for extensive surface preparation.
- Ternary Carbide Nitride Thermal Spray Abradable Seal
A ternary carbide and nitride thermal spray coating on a substrate forms an abradable seal for gas turbine engines.
- Aluminum Abradable Coating for Thermo-Mechanical Fatigue Resistance
Aluminum alloy coating with fine low thermal expansion particles reduces thermo-mechanical fatigue and compressive stress in compressor components.
- Environmental Barrier Coating Backside Heating Control
Backside heating of a substrate controls frontside surface temperature during thermal spray deposition of environmental barrier coatings.
