The surface of gadolinium was covered with a layer of Al film(10-15 μm) by hot-press.Corrosion resistance,thermal conductivity and diffusivity of the composites were studied.As a result,temperature and pressure are the main factors that influence the combination of Gd and Al,and the effect of pressure is especially obvious.When the pressure exceeds 700 MPa,the binding force reaches 9 MPa.After coating,corrosion resistance of the composites is significantly improved,Corrosion rate is significantly reduced and mass loss reduced to one-tenth of pure Gd after 15 days.The current density decreases by an order of magnitude and corrosion potential increases by 0.3 V.The thermal conductivity of the composites is 11.12 W·m-1·K-1.Due to good thermal diffusion coefficient of aluminum,the magnetic work piece coated with Al film might show better heat transfer performance.
