Abstract

1. Способ химической обработки поликристаллических алмазных агрегатов, синтезированных в присутствии катализатора - сплава на основе никеля и хрома, путем воздействия минеральных кислот при нагревании, отличающийся тем, что, с целью повышения абразивной способности алмазных агрегатов, их обрабатывают при 20 - 100C смесью соляной кислоты концентрации 35 - 38%, азотной кислоты концентрации 61 - 68% и воды в объемных соотношениях от 1:1: 1 до 1:1:2.2. Способ по п.1, отличающийся тем, что обработку ведут в течение 10 - 15 мин.
