Paper Title:
Influence of the Parameters on the Laser Deposited TiAl Layer
  Abstract

TiAl based intermetallic compound claddings were produced on TA15 alloy surface by using laser depositing technology to melt Ti-46Al-2Cr metal powders. An interface layer between TA15 substrate and the TiAl claddings was formed. The influence of laser power, scanning speed and number of cladding layers on the interface layer and the hardness of TiAl claddings were investigated. Higher laser power and lower scanning speed made the interface layer thicker. Increasing the laser power and especially the scanning speed could improve the hardness of the TiAl claddings. When the second TiAl layer was deposited, there was no interface layer formed between the two TiAl layers, but the hardness of the first layer decreased and the second TiAl layer was softer than the first layer due to the rough microstructure.
