LIU MINGMING / WANG BINBIN / LI KANG / HUANG HONGWEI

The invention relates to a preparation method of a diamond sintered body and the diamond sintered body. The preparation method comprises the following steps: carrying out nitriding treatment on diamond micro-powder to form pits and/or defects on the particle surface of the diamond micro-powder, and obtaining micro-powder after nitriding treatment; and carrying out pressure sintering treatment on the micro powder to obtain a diamond sintered body. According to the preparation method disclosed by the embodiment of the invention, the diamond sintered body can be generated without an adhesive, and the hardness and compactness of the diamond sintered body can be improved.

本公开涉及一种金刚石烧结体的制备方法及金刚石烧结体。该制备方法包括：对金刚石微粉进行氮化处理，以在金刚石微粉的颗粒表面形成凹坑和/或缺陷，并得到氮化处理后的微粉粉料；以及对所述微粉粉料进行加压烧结处理，以得到金刚石烧结体。根据本公开实施方式的制备方法，可以无需黏结剂而生成金刚石烧结体，并且有利于提高金刚石烧结体的硬度和致密度。
