Ocular Protection from Laser Hazards. Phase 2
Abstract
Thin films are used in numerous applications including optics, electronics and surface protection. Physical vapor deposition (PVD) is the commonly used method to produce thin film coatings. Standard PVD techniques produce films with inherent weaknesses in optical and mechanical properties because of their typical columnar microstructure. This structure is a result of the low mobility of the condensed atoms or molecules on the substrate surface. This is particularly true for coating of plastics, where the substrate temperature needs to be kept low (around ambient). Reactive Ion Plating Deposition (RIPD) is an innovative technique which densifies the growing thin film by enhanced surface mobility as well as by continuous ion bombardment. This results in durable well adhering thin films at relatively low substrate temperatures. This technique and other hybrid ion enhancement processes will be investigated and directed toward production-oriented applications. Further refinement of the RIPD technique evaluated in the Phase I effort will be performed.
