Hard coatings based on thermal spray and laser cladding (2009)
Khanna, A.S., Kumari, S., Kanungo, S., Gasser, A.
Thermal spray and laser cladding have been used to develop hard coatings. HVOF and laser glazing techniques were used to form hard and corrosion resistant coatings, using WC/Co, impregnated in Ni-Cr...
Raj, Baldev, Jha, B. B., Khanna, A. S., Bhattacharya, D. K.
Acoustic emission studies on oxidation of Cr-Mo steels over a wide range of temperatures is described; events, ring down counts, rise time, event duration, and root mean square voltage were...
Influence of Grain Size on the Oxidation Resistance of 2 1/4Cr-1Mo Steel. (1998)
Singh Raman, R. K., Khanna, A. S., Tiwari, R. K., Gnanamoorthy, J. B.
The effect of grain size on the oxidation of 2 1/4 Cr-1 Mo steel has been studied at 823 K in air; the oxidation rate was found to decrease with increasing grain size ( 16 to 59 microns ); the...

Khanna, A.S., Singh Raman, R.K., Kreutz, E.W., Terrance, A.L.E.
Stainless-steel powder was coated on mild steel substrated using a plasma coating technique. The porous coating thus obtained was modified using laser treatment. The oxidation behaviour of the...
Oxidation behaviour of alloy 713 coated with Y, Ce, or Hf using laser glazing technique (1989)
Wissenbach, K., Gasser, A., Kreutz, E.W., Khanna, A.S., Quadakkers, W.J., Schuster, H.
Laser glazing was carried out on Alloy 713 after coating with yttrium, cerium or hafnium. Compounds rich in aluminium and the coated material were detected on the laser treated surface. Both the...
