METHOD OF PRODUCING AlO-Al COMPOSITE MATERIAL Russian patent published in 2010 - IPC C22C1/05 B22F3/23 C04B35/65

Abstract RU 2398037 C2

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly to production of composite materials. It can be used for production of strong wear-resistant parts, abrasive tools and sealing elements. Billet is produced by pressing the burden that comprises aluminium powder that features plate-like shape of particles and binder, and sintering in SHS-conditions. Sintered product is placed in mould, heated to 600÷775°C and 9÷12 MPa pressure is applied thereto for 1÷30 minutes to product deformation of 1.18÷1.25. Then product is cooled under pressure to 590÷650°C at the rated of 5÷10°C/min. Now, pressure is removed and product is cooled to ambient temperatures at the rate of 2.5÷4°/min.

EFFECT: high wear resistance, antifriction properties and resistance to propagation of fatigue cracks.
