Description

оксидна  пленка толщиной 6 1-2 мкм, алее следует карбонитридный слой, толщиной 5-8 мкм, с твердостью 1110- 1300 НУ, затем переходна  зона с б 80- 100 мкм, и 680-730 HV, и далее стальна oxide film 6–1–2 µm thick, followed by a carbonitride layer 5–8 µm thick with a hardness of 1110–1300 NU, then a transition zone with b 80–100 µm, and 680–730 HV, and then

основа с 550-590 HV.base with 550-590 HV.

Последним этапом технологического процесса  вл етс  очистка подщипников от следов азотировани , включающа  промывку Б гор чей воде, ультразвуковую обработку в моющем растворе, промывку и сущку.The final stage of the technological process is to clean the liners from traces of nitriding, including washing B with hot water, ultrasonic treatment in a washing solution, washing and substance.

Изобретение позвол ет повысить производительность и увеличить термостойкость подщипников до 500-550° ,С.The invention makes it possible to increase the productivity and increase the heat resistance of the ball bearings up to 500-550 ° C.
