Abstract:In order to fully understand the effect of the cold rolling ratio of the catalyst on the synthesis of diamond, the diamond synthesis experiments were carried out using the catalysts with different cold rolling ratios. The axial density and texture on the cold rolling surfaces were measured by X ray diffractometry and the results were analysed using the theory of diamond synthesis. The results show that the cold rolling ratio of the catalyst seriously affects the synthesis of diamond, and the best cold rolling ratio in this research is 83%, and that this effect is caused by the change of texture of the catalyst, especially the change of the distribution of the {111} crystallographic planes on the rolling surface.
