Abstract:y reference to the test standard on bulletproof clothing of American Association for Justice(AAJ),the bulletproof properties of uncovered target plates of a new Ti-120 alloy were studied,and compered with pure titanium TA2,stainless steel,Nylon and keviar etc.The results showed that the new alloy,which has lighter density than steel and cheaper.than Nylon,keviar,has a good resistance to perforation and small hollow of shell crater.Therefore,the Ti-120 alloy plate with thickness of 2.6mm will be ideal materials of bulletproof clothing

Abstract:he electrochemical deposition of aluminium from NaCl-AlCl3 molten salt system has been studied by using cyclic voltammogram.In the basic salts the species reduced at the cathode are AlCl4 ions,while in the acidic salts the species reduced are Al2Cl7 ions.There are equilibrium reactions between the ionic species,which influence the reduction of aluminium at the cathode.The reduction reaction of Al2Cl7 is quasireversible,and the reduction mechanism is very complicated.There may be some pre-chemical step or camo-catalytic reaction mechanism.
