| 释义 |
Hydrogenography is a combinatorial method based on the observation of optical changes on the metal surface by hydrogen absorption.[1] The method allows the examination of thousands of combinations of alloy samples in a single batch. HistoryIn the 1996 report of the method, thin films were coated with yttrium and lanthanum topped with a layer of palladium for the diffusion of hydrogen. The rate of absorption of hydrogen resulted in typical optical properties.[2] In the 2008 report magnesium, titanium and nickel are eroded and sputtering deposited in different ratios onto a transparent film in a thin layer of 100 nanometres following exposure to hydrogen in different amounts resulting in optical differences,[3] See also
