Paper Abstract

Boron phosphide (BP) has outstanding mechanical, optical and thermal properties. It has been prepared as a single crystal and as a coating by various techniques. BP coatings have been shown to combine good broad-band transmission with exceptional durability and erosion protection of all common infrared optical materials. Their protective properties on various substrates have been assessed in detail in whirling arm rain erosion tests and by water jet impact measurements, and the thickness dependences determined. Comparisons have been drawn between BP and other durable coatings. The productionising of BP coating processes is well advanced after overcoming a number of problems, in particular the exceptional hazards presented by the feedstocks.
