Physical and mechanical properties of Ti/Al multilayer heat releasing coatings

Original language description

The paper reports on physical and mechanical properties of sputtered Ti/Al multilayer coatings with a bilayer thickness Lambda ranging from 2 to 172 nm releasing heat during annealing. The temperature Thr at which the heat is released during reaction between Al and Ti atoms is investigated. It was found that: 1) Thr: a) decreases from ~420 to 390 oC for the coatings with Lambda decreasing from 172 to 17 nm; b) ranges from ~480 to ~600 oC for the coatings with Lambda LESS-THAN OR EQUAL TO 12 nm; 2) the heat DeltaH(Ti/Al) evolved in the reaction increases from 5 to 35 kJ/mol with increasing Lambda. Besides, it is shown that: 1) the heat can be released also during one pulse of the rapid thermal annealing up to 600 oC with heating rate 100 oC/s; 2) the released heat results in a strong interaction of the Ti/Al multilayer coating with Si substrate. The mechanical properties of the as-deposited Ti/Al multilayer coatings are also given.
