摘　　要：陶瓷基板电热组件具有加热均匀性好、电热转换效率高等优点,广泛应用于需低温加热场合,然而传统金属-陶瓷共烧技术因成本高、效率低而制约发展。通过采用电铸工艺在陶瓷基板上制备镍铜合金电热组件,研究发现镍铜合金电铸层的平均晶粒尺寸随着电铸液温度的升高而增大,电阻率随晶粒尺寸的增大而减小,同时电流密度会显著影响镍铜合金电铸层中镍的含量,进而影响镍铜合金电铸层的线膨胀系数。Ceramic electrothermal components are widely used in situations that require low-temperature heating because of the advantages of good heating uniformity and high electrothermal conversion efficiency.However,traditional metal ceramic co-firing technique is limited in development due to its high cost and low efficiency.By using the electroforming process to prepare nickel-copper alloy electrothermal components on ceramic substrates,it was found that the average grain size of the nickel-copper alloy casting layer increases with the increase of the solution temperature,while the resistivity decreases with the increase of grain size.Meanwhile,the current density significantly affects the nickel content in the nickel-copper alloy electroforming layer,thereby affecting the linear expansion coefficient of the electroforming layer.
