Two-stage firing of wear-resistant products of complex configuration made of aluminum-zirconium ceramics

Year: 2024

Type: article

Abstract: The modes of two-stage ﬁring of wear-resistant products of complex conﬁguration made of aluminum-zirconium ceramics are described. The ﬁring mode of ceramics in the ﬁrst stage is carried out in air at a maximum temperature of 1500 oC with isothermal exposures of 2 and 8 hours at 1300 and 1500 oC, respectively. At the second stage, the method of hot isostatic pressing (НIР) was used at a maximum temperature of 1490 °C with a short-term exposure of 1 hour. The established modes of two-stage ﬁring ensure the production of aluminum zirconium ceramics with a ﬁne-grained structure (0.5‒2.5 microns), a relative density of 99.3 %, with a high level of physical and mechanical properties and resistance to aging.
