摘要

Laser cladding experiment of Ti+ Al + Si0₂ +C was carried out on Ti6A14V alloy substrate，then the microstructure of the clad layer was analyzed with SEM and its Anti - oxidation function was discussed.Analyses microstructure show that the clad coating can be divided into three zones along the depth direction：clad binding and heat - afected zones. Ti₅Si₃ in the clad zone exists in the form of fine dendrites ， TiAl matrixfilling among Ti₅Si₃ dendrites plays a role of connecting the Ti₅Si₃ with the TiAl₃ and transferring load so the clad coating has been strengthened obviously.
