▎ 摘　　要

NOVELTY - Magnetic isolating material with counter-potential crystal comprises a non-magnetic layer (1), a fusion layer (2) and a magnetic isolating layer (3). The non-magnetic layer is connected with the magnetic isolating layer through the fusion layer. The non-magnetic layer is made of graphene reinforced titanium alloy. The magnetic isolating layer is made graphene-enhanced iron-nickel-cobalt alloy. The fusion layer is formed by intermediate fusion of non-magnetic layer and the magnetic isolating layer when the temperature is lowered to 1217 plus minus 1.5degrees Celsius at 3652degrees Celsius. USE - The material is useful for magnetic fluid sealing system rotating shaft comprising but are not limited to aerospace, chemical, petrochemical industry and biological medical field. ADVANTAGE - The material: utilizes the mode of partial fusion of graphene-enhanced titanium alloy and graphene-enhanced iron-nickel-cobalt alloy to realize the preparation of anti-potential crystal magnetic isolation material; directly coats the highly dispersed graphene on the surface of the alloy powder to form a more obviously refined microstructure in the process of taking the alloy powder from the drill bit; and has high tensile strength of anti-potential crystal magnetic insulating material after forming as 1019 MPa, high yield strength as 998 MPa, excellent mechanical properties compared with the prior art, high magnetic permeability on the surface, and non-permeable and non-magnetic properties of the substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the magnetic isolating material with counter-potential crystal. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the magnetic isolating material with counter-potential crystal. Non-magnetic layer (1) Fusion layer (2) Magnetic isolation layer (3)
