METHOD OF SEALING FIXED SPLIT JOINTS |
摘要 |
FIELD: machine building.SUBSTANCE: coating structure is formed in magnetic field on pre-textured chemically-etched surfaces of the part 100. Said coat consists of magnetostrictive substrate and sealing elastically deformable outer layer. Sign of magnetostriction is selected subject to necessity in increase of substrate material volume at compression or expansion. Joint is operated at residual magnetisation of coat material. Coat substrate is made of magnetostrictive hard materials. Note here that, in operation of joint in compressible gases or liquids, negative magnetostriction materials are used while in incompressible gases or fluids, positive magnetostrictive materials are used.EFFECT: higher tightness.3 cl, 3 dwg |
