碱土团粒更少,仅为16.5%,但经化学措施改良后也可达到32.55%。

Abstract : When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.

摘要 ： 当两种不同放在熔融碱碱土氯化物盐浴中时,较易腐蚀会沉积在较难腐蚀上。

When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.

当两种不同放在熔融碱碱土氯化物盐浴中时,较易腐蚀会沉积在较难腐蚀上。
