摘要
通过化学镀方法在玻璃纤维表面沉积了Ni-Fe-W-P合金,所用镀液经钯盐法测试,稳定性很好,所得镀合金玻璃纤维经热震实验后表面无鼓泡、起皮现象,说明镀层的抗冲击强度高,结合力良好。利用扫描电镜观察了镀层的表面形貌,同时使用X射线能谱仪对镀层成分含量进行了分析,镀层中钨的质量分数最大可达22.2%,并得出了硫酸镍、硫酸亚铁、钨酸钠浓度对镀层导电性能的影响情况,制备的镀合金玻璃纤维电阻率为28.3×10-3?·cm。对玻璃纤维合金层进行的XRD分析表明,在镀态下为非晶态结构,玻璃纤维热稳定性好,适宜的工作温度范围低于250oC。最后对所得Ni-Fe-W-P合金玻璃纤维的电磁参数进行了初步的测定与分析,所得镀金属玻璃纤维的磁损耗为0.05475;介电损耗为2.18424,镀层合金为软磁性材料。
The Ni-Fe-W-P alloy was deposited on the surface of glass fiber via electroless plating process. The bath was very steady through the Palladium salt test. There were no phenomena of peeling and blistering on the surface of the Ni-Fe-W-P alloy glass fiber in the thermal shock test. It shows that the deposit has the high impact strength and the good adhesion. The morphologies of the coatings were observed through the scanning electron microscope （SEM）. The elements and their content were tested and analyzed through energy dispersion X-ray analysis （EDXA）. The tungsten content was 22.2wt% at most. The effects of concentrations of NiSO4, FeSO4 and NaEWO4 on the conductivity of the coatings were studied. The resistivity of the Ni-Fe-W-P alloy glass fiber reached 28.3×10^-3Ω·cm. The alloy coating on glass fiber was analyzed by XRD, the results indicate that deposit has an amorphous structure and good heat stability. The suitable work temperature range is lower than 250℃. At last, the electromagnetic parameters of the Ni-Fe-W-P alloy glass fiber were tested and analyzed. The magnetic loss reached 0.054 75 and the dielectric loss reached 2.184 24. The alloy as plated is a kind of soft magnetic material.
