Plasma optical emission spectroscopy of laser cladding for process control and oxidation behavior of laser clad NbAl alloys

Spectroscopic diagnostics based on the plasma optical emission spectroscopy has been employed in this investigation to infer composition, thickness, and temperature of the clad during laser cladding of Nb-Al-Hf alloys on Nb substrate. Isothermal oxidation behavior of the laser clad NbAl$\sb3$ based alloys containing: up to 1.0 at. % B; 1.5 at. % Hf; and 3 or 6 at. % Ti has been investigated at 800$\sp\circ$C, 1200$\sp\circ$C, and 1400$\sp\circ$C.
