The arrangement of the first lamination layer with larger pore diameter is used for effective escape of gas generated during product production process. According to production requirements for products, a pore diameter of the third lamination layer can be adjusted to be not larger than that of the first lamination layer. Thus mechanical strength and gas exhaust capacity can be balanced.

Abstract: Provided is a method of repairing structures on the Lunar surface using Lunar regolith containing metallic coatings. An ultra-portable and low-pressure cold spray system is utilized to consolidate coatings. This system can be easily transported to space, reducing the payload. Lunar regolith is added to the metal powder before cold spray deposition. Lunar regolith increases the tampering effect during cold spray deposition, thereby causing severe plastic deformation of the metal powders and providing a coating with high quality and minimum porosity. The presence of Lunar regolith increases the hardness of the coating and improves wear properties. Coatings on a large area can be made rapidly without much surface preparation. These coatings can be rapidly applied to various Lunar structures to repair, reinforce, and restore (RRR) functionality and performance in the Lunar environment.
