Use of a zirconium alloy coated with an homogeneous polycrystalline diamond layer for a nuclear reactor
Original language description
A layer protecting the surface of zirconium alloys used as materials for nuclear reactors is formed by a homogenous polycrystalline diamond layer prepared by chemical vapor deposition method. This diamond layer is from 100 nm to 50 μm thick and the size of the crystalline cores in the layer ranges from 10 nm to 500 nm. Maximum content of non-diamond carbon is 25 mol%, total content of non-carbon impurities is maximum up to 0.5 mol%, RMS surface roughness of the polycrystalline diamond layer has a value less than 40 nm and thermal conductivity of the layer ranges from 1000 to 1900 W·m−1·K−1.nCoating of the zirconium alloys surface with the described polycrystalline diamond layer serves as a zirconium alloys surface protection against undesirable changes and processes in the nuclear reactor environment.nnPriorita CZ305059 - RIV: RIV/68378271:_____/15:00447999
