Summary

This paper investigates the use of Cold Spray Additive Manufacturing (CSAM) to deposit lunar regolith simulant (LHS-1D) onto polymeric substrates, specifically polytetrafluoroethylene (PTFE). The study evaluates the microstructure, mechanical properties, hardness, adhesion strength, and thermal resistance of the resulting coatings. The coatings demonstrate excellent adhesion and improved thermal resistance compared to pristine PTFE. The provided text appears to be a mix of URLs, metadata, and identifiers related to a scientific paper, likely from the journal 'Surfaces and Interfaces'. It includes DOIs, publication dates, and other technical details, but no actual content or abstract of the paper is present. The paper explores the application of cold gas dynamic spraying (CGDS) for coating lunar regolith simulant on a polyetheretherketone (PEEK) substrate. The study investigates the effects of varying spray parameters, such as gas pressure, standoff distance, and powder feed rate, on the microstructure and mechanical properties of the resulting coatings. The results indicate that optimal parameters can produce dense, adherent coatings with good wear resistance and thermal stability,
