摘要	Metallic foams have many applications in industry and are made using various methods. However, no suitable method for heating Ni-Cr alloy foam has been available. A method of preparing Ni-Cr alloy foam by an electrodeposition technique is described in the present paper. The method includes the following steps: establishing electrical conductivity of organic foam; electroplating of a Ni layer; electroplating of a Cr layer; eliminating the organic matrix and a homogenisation heat treatment. The plating solutions and process parameters of electrodeposition are introduced in detail. Homogenisation of the samples was carried out in a sealed quartz tube at 1100 degrees C and the homogenisation time was determined by experiment and calculation. Experimental results are shown indicating that the Ni-Cr alloy foam made by this electrodeposition technique had a three-dimensional reticulated structure and formed a single phase Ni based solid solution. Also, the apparent resistivity was measured and it is demonstrated that the higher resistivity of the foam gave it good electrical heating properties.
