Abstract

A coating reinforced with in situ synthesis of Ti

SiC

particulates was fabricated successfully on the Ti-6 Al-4 Valloy by the low oxygen partial pressure fusing technique in the Al-Si-TiC powders system.The results show that the role of aluminum is served as a diluent agent to decrease the molar fraction of reactant in the slurry and as a activator agent to accelerates the coating formation

as a assistant agent to decrease the reactive temperature for the formation of Ti

SiC

as deoxidant agent to remove the oxygen in the system

as stuffing agent to favor the densification of coating during the fabrication of Ti

SiC

which provide an easier route for fabrication of the Ti

SiC
