Microwaves at 2.45 GHz used to ignite the combustion synthesis of Ni and Al powder mixtures to produce NiAl and a complex Ni-Al-Ti intermediate layer on titanium. Wear resistance of the complex Ni-Al-Ti layer were measured in dry-sliding against alumina using a tribometer. Other mechanical properties, as scratch resistance and elastic modulus, were measured. These showed that Ni-Al-Ti layer presents increased performances with respect to polycrystalline NiAl.

Abstract
Microwaves at 2.45 GHz used to ignite the combustion synthesis of Ni and Al powder mixtures to produce NiAl and a complex Ni-Al-Ti intermediate layer on titanium. Wear resistance of the complex Ni-Al-Ti layer were measured in dry-sliding against alumina using a tribometer. Other mechanical properties, as scratch resistance and elastic modulus, were measured. These showed that Ni-Al-Ti layer presents increased performances with respect to polycrystalline NiAl.File in questo prodotto:
