Abstract

Thin films were deposited onto ZnS as a means of strengthening and toughening. Fracture strength increases of up to 40% have been observed. These mechanical property enhancements were found to be related to the compressive stress in the deposited films. Rain erosion resistance is also enhanced through the application of compressively stressed thin film coatings.
