Effect of oxide additions on the properties of plasma-sprayed Y-Ba-Cu-O coatings
K A Durga Prasad K C Lahiry D Maheswara Reddy S C Mohan S Rajendra Kumar N Ramadass S Ravichandran R Somasundaram G Swaminathan K Venugopal
Plasma-spraying is a potential technique for forming flexible tapes from the brittle high
T c oxides. It is possible to obtain superconducting YBa2Cu3Ox coatings by a suitable heat-treatment after spraying. In an effort to improve the critical current densities of the coatings, the effect of additions of Ag2O, Bi2O3 and SnO2 to the YBa2Cu3Ox powder used for spraying was studied. The maximumJ c value of 75 A/cm2 was obtained for the sample doped with 5% SnO2. -

CO2 laser processing for reducing core loss of cold-rolled grain-oriented silicon steel
S C Patil G Swaminathan Manoj Kumar P V Sastry S B Ogale S M Kanetkar A Pramanik
Non-contact processing technique involving the use of CW and pulsed CO2 laser irradiation has been used for reducing the core loss of cold-rolled grain-oriented silicon steel. Laser scribing perpendicular to the rolling direction resulted in a refinement of domain wall spacing which subsequently reduced the loss of silicon steel. It was found that laser irradiation was more effective in a specimen with higher magnetic induction (Hi-B) and the loss was reduced by more than 10% under optimum conditions of the laser irradiation and the scribing speed. Since laser processing is a non-contact technique, it can be easily applied to the production line of the silicon steel.
