The nondiamond carrbon layer 15-20A thick has been foundon surface of diamond that had been treated by H2/ That was done by Reverse Proton Dispersion and XPS.This layer according to the data on IR- spectroscopy of diffusional reflection is characterized by the presence of clusterreticularstructure bearing oxigen and hydrogen-containing groups. The layer that have been found cosiderably change the surface diamond properties. At temperature 20-550C the treatment of diamond by H2 and CH4 leads to change of hydrofobic-hydrofilic properties. The process of diamond oxidation by air (650C) slow down after methanization and the biggest effect is achieved by treating at 550C. The most ingibitory on diamond oxidaizing by water vapour (at 900C) would be methanizing at 20-250C. Hidrogen treatment at 20-250C ingibits the reaction with the air. The diamond modification by H2 and CH4 causes an abrupt increase of the microwave surface conductivity in comparison to pure diamond
