Liberation of hydrogen gas would be increased rapidly and sic particles on the surface might be dispersed if the current density exceed the upper limit . furthermore , nickelous hydroxide would be deposited because the ph of plating solution nearby the surface rapidly increased . all of above might result in coating deterioration 若電流密度過大,超過所允許的上限值,會析出大量的氫氣,可能沖散表面覆蓋的sic微粒,而且易使磨頭表面鍍液ph值急劇上升而形成氫氧化鎳沉淀,導致鍍層質量惡化。

Fe - ni alloy fiber were first prepared in a mixed solution of ferrous and nickelous salts , using kbh4 as a reducing agent . conditions , such as quantity of naoh , concentration of salts , and species of surfactants , of preparation of fe - ni alloy were studied . the result show that fe - ni alloy were soft magnetic materials and they exhibited superparamagnetization at room temperature that have been widely used in industry 本文用液相還原法首次制備出纖維狀的fe - ni合金、球形的fe - co 、 co - ni合金、 fe - co - ni合金粉體材料,并對其性能進行了分析和測試,結果表明:這些合金粒徑小,比飽和磁化強度較大,矯頑力為零,呈現超順磁性,是非晶態的軟磁材料。
