Abstract

Pilkington Optronics (Barr & Stroud), in conjunction with the Defence Research Agency (Malvern, UK), has an ongoing development program for ultradurable coatings. Such coatings enhance environmental durability of infrared (IR) transmissive windows and domes for severe environments, such as those encountered in airborne systems. In particular, these coatings are required to provide protection against high velocity rain and sand impact. This program has to date produced one of the most effective sand and rain protective coatings, based on phosphide materials, specifically boron and gallium phosphide. The phosphide coatings are incorporated into anti-reflective (AR) multilayers, providing high transmission over the required IR waveband. Such AR coatings have been shown to be very effective in protecting windows and dome materials from rain and sand/dust impact damage. Results of single and multiple water jet impact tests, whirling arm rain erosion and sand erosion are presented. Current performance of AR coatings incorporating BP or GaP is presented. Combining BP and GaP in a composite structure, thereby maximizing IR transmission while maintaining sand and rain erosion protection, is described.
