Claims (10)

1. Способ получения абразивного порошка из плотного и, в значительной мере, не имеющего пор кермета, состоящего из карбидо-титановой основы и карбидов, нитридов и/или боридов Vb, Vb и VIb подгруппы периодической системы, в котором в качестве исходных веществ применяют оксид титана и элементы подгрупп, которые расплавляют в электродуговой или плазменной печи в присутствии углерода в качестве восстановителя, и превращают в королек твердого сплава, и в заключение продукт измельчают и классифицируют.1. A method of producing an abrasive powder from a dense and substantially pore-free cermet consisting of a carbide-titanium base and carbides, nitrides and / or borides Vb, Vb and VIb of a subgroup of the periodic system in which oxide is used as starting materials titanium and elements of subgroups, which are melted in an electric arc or plasma furnace in the presence of carbon as a reducing agent, and converted into a hard alloy crown, and finally the product is ground and classified. 2. Способ по п. 1, отличающийся тем, что исходные вещества реагируют друг с другом путем непосредственной экзотермической реакции. 2.
