FIELD: mechanical engineering; creation of considerable forces at small sizes of force exciter. SUBSTANCE: method consists in forming thin-walled ferrule on revolving mandrel by thermal spraying of material. Material is applied on base of binder, after which it is hardened and sleeve is removed from mandrel. Mandrel is loaded by constant pressure through introducing working medium into its closed cavity. Application of material on base of binder is effected by layer-by-layer winding the material on outer surface of thin-walled ferrule. After hardening, pressure of working medium is reduced and mandrel is unloading. EFFECT: reduced labour consumption; enhanced durability of hydraulic power cylinder. 1 dwg
