Copper depositions onto corrugated substrates representative of ~100-200 GHz waveguides are presented. Cross-sectional micrographs, material porosity, and surface roughness are reported for various spray parameters, post-deposition treatments, and substrate materials. The data was produced by James Ridzon et al. at the Plasma Science and Fusion Center and last updated on 2026-06-20.
Use Cases
- Optimizing cold spray manufacturing parameters based on reported porosity and roughness data.
- Comparing the performance of different substrate materials and corrugation aspect ratios for waveguide fabrication.
- Validating computational models of copper deposition in corrugated structures using the provided micrographs.
- Assessing the feasibility of cold spray as a novel fabrication pathway for internally corrugated waveguides.
Strengths
- Reports specific measurements including material porosity and surface roughness.
- Covers multiple experimental variables: spray parameters, post-deposition treatments, substrate materials, and corrugation aspect ratios.
- Includes cross-sectional micrographs for visual analysis of deposition quality.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update was 2026-06-20.
