摘要
Electroplating of Al-Ti alloy in AlCl3-BPC (n-butylpyridinium-chloride) melts containing TICln (n=2,3,4) has been studied at 300∼450K. The cathode surface was covered with a smooth and dense metallic layer which consisted of mainly Al and included Ti. The surface became uneven with the increase in Ti content in the deposit. Intermetallic compounds of Al and Ti were not detected even in the deposit containing Ti more than 10 at%. Electrolysis in TICln (n=2,3,4)-BPC melts has been tested above the melting point of BPC (∼405K). Metallic electrodeposit was not obtained under any condition in these melts.
