Abstract
Novel diamond thin films deposited on a metal or ceramic composite comprising a matrix having dispersed therein finely divided diamond or diamond-like particles are useful in improving the erosion resistance of materials used for long wave infrared transmitting applications such as domes and infrared windows.
Claims12
A diamond coated article comprising a uniform film of diamond deposited on a composite comprising a three dimensional matrix having uniformly dispersed throughout at lateral distances from about 0.01 to about 5.0 .mu.m finely divided diamond particles at a volume concentration of from 0.1 to about 75 percent wherein the said finely divided diamond particles have a particle size of from about 0.01 to about 5.0 micrometer diameter;
- the matrix has a particle size of from about 0.5 micrometer to about 50 micrometer;
- and wherein said matrix transmits infrared light at wavelengths from about 1 to at least 10 micrometers and said composite transmits infrared light at wavelengths from about 8 micrometers to about 15 micrometers.
