Functionally Gradient Coating Layers Produced by Laser Alloying / Cladding
Abstract Investigations have been made of functionally gradient materials (FGMs) produced on Ti-based and Ni-based substrates by depositing a series of superimposed alloyed or clad layers using a CO2 laser with a continuous powder feed facility. With titanium substrates the objective has been to enhance the resistance to high temperature oxidation and to erosion through the formation of FGM coating layers containing aluminium. In the alloying process, aluminium powder is fed into the laser generated melt pool, while in cladding the feed mixture contains aluminium and titanium powder. Layers with Al contents up to 44at% covering the range of Ti3A1 and TiAl have been produced. Also composite layers have been produced incorporating partially dissolved ceramic particles (eg TiB2) in a titanium aluminide matrix. Observations are reported of microstructural and compositional features of the FGMs together with data on hardness, oxidation, and erosion resistance.
