Description

3 верхностное упрочнение, отличающнйс   тем, что, с целью повышенн  усталостной прочности и долговечности, после термической обработки изделие одновременно подвергают дробеструйной обработке сна-5 ружи, обкатке роликами изнутри и циклическому деформированию в упруго-пластической области. 4 Источники информацин, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР № 269970, С 21D 7/06, 1970. 2. Авторское свидетельство СССР № 267663, С 21D 7/04, 1969. 3. Metall Progress, 1953, 63, 107.3 surface hardening, characterized in that, in order to increase fatigue strength and durability, after heat treatment, the product is simultaneously subjected to shot-blasting of sleep-5 guns, run-in from inside and cyclic deformation in the elastic-plastic region. 4 Sources of information taken into consideration in the examination 107
