摘要
本文对复合镀层的发展进行了回顾和展望。研究了用直流电代替不对称交流电起镀的室温镀铁的原理和工艺条件。测定了镀液中B_4C含量对镀层中B_4C含量的影响以及电镀温度对镀层硬度、内应力的影响。
Reviewing and prospecting the development of the process of composite
oating,
The principles and technological conditions are studied of substitution of
the direct current for the non-symmetric alternating current in galvanizing
eron at room temperature.Measurements have been made for the B_4C contents in
llectrolyte which influence B_4C contents in galvanizing layer, and for the inf-
uence of galvanizing temperature on the hardness and internal stress of compo-
site coating.
