Process to fabricate light bulb base fitting with coating of encapsulated nano-particles giving protection from ultraviolet light

摘要

In a cold gas spray application for the fabrication of components from nano-particles, a cold gas jet bearing the particles (19) is directed at a coated substrate. The particles employed are micro-encapsulated agglomerated micro-particles (27). The delivery energy imparted on the capsules causes the capsules to rupture on impact with the substrate. The nano-particles are deposited on and absorbed by a contact layer and the capsule residues are removed in a subsequent process. The energy imparted to the incoming gas and the type of nano-particles are varied as required throughout the process. the coating of nano-particles is subsequently heat-treated. The nano-additives inhibit the formation of granular growth. The substrate is a plastic light bulb socket.
