Abstract

Intermetallic phase formation was studied in powdered Ti-Ni-Al system under layerwise laser cladding with aim of the fabrication of the gradient of properties due to a change in the concentration relationship Al into the NiTi powder mixture from one layer to the next. The relationships between the laser cladding parameters and the intermetallic phase structures in the consecutively cladded layers were determined. For studying the structure formation an optical microscopy, measurements of microhardness, SEM with EDX analysis were used after the laser synthesis of intermetallic compounds. Microhardness doubling from 500 HV to 1000 HV was achieved due to nitinol matrix enrichment by Al that is perspective for aerospace applications.
