METHOD OF PRODUCING FRICTIONAL ARTICLES Russian patent published in 2018 - IPC B22F7/04 B22F3/12 

FIELD: technological processes.

SUBSTANCE: invention relates to production of frictional articles. Method comprises applying and pre-baking a free-floating layer of friction material onto a steel support base and sintering under a load in a protective atmosphere. Molding gaskets made of heat-resistant material with a system of oil-draining channels and grooves on the surface are applied on the pre-baked layer of friction material. Sintering under load is carried out at a pressure of 20–25 kg/cm² with the production of a friction liner with a system of oil-draining channels and grooves on a steel bearing basis. Reducing the seal pressure of the friction material, increasing the strength of the friction liner to the steel base, combining the sintering process and forming a system of oil-draining channels and grooves with a depth of 0.65–0.9 of the thickness of the friction liner.

EFFECT: reducing the seal pressure of the friction material, increasing the strength of the friction liner to the steel base, combining the sintering process and forming a system of oil-draining channels and grooves.
