Abstract
Способ получения инструментального материала, включающий подготовку исходного сырья α-AlO, введение модифицирующих добавок, перемешивание, формование, обжиг при температуре 1200-1300°С, предварительную механическую обработку, окончательное спекание при температуре 1750-1780°С, окончательную механическую обработку, нанесение покрытия в вакууме при температуре не ниже 850°С, отличающийся тем, что, с целью повышения вязкости разрушения, в качестве материала покрытия применяют псевдо-бета или бета-сплавы титана или циркония, после нанесения покрытия проводят охлаждение со скоростью 60-150°С/мин в инертной среде, а затем наносят слой - α-AlO.The method of obtaining tool material, including the preparation of the raw material α-AlO, the introduction of modifying additives, mixing, molding, firing at a temperature of 1200-1300 ° C, preliminary mechanical processing, final sintering at a temperature of 1750-1780 ° C, final machining, coating in vacuum at a temperature not lower than 850 ° C, characterized in that, in order to increase the fracture toughness, pseudo-beta or beta alloys of titanium or zirconium are used as the coating material I conduct cooling at a speed of 60-150 ° C / min in an inert atmosphere, and then apply a layer of α-AlO.
