The vertical axis wind turbines are simple in construction, self-starting, inexpensive and can accept wind from any direction without orientation. A combined Savonius–Darrieus type vertical axis wind rotor has got many advantages over individual Savonius or individual Darrieus wind rotor, such...

The present study aims at enhancing the wear resistance of Ti–6Al–4V by laser surface nitriding. Laser surface treatment has been carried out by melting of the sand blasted Ti–6Al–4V substrate using a high power continuous wave Diode laser with nitrogen as shrouding environment (at a gas...

The present study aims at enhancing the wear resistance and biocompatibility of Ti-6Al-4V by forming a thin layer of oxide. Surface oxidation has been carried out by controlled heating of the surface of Ti-6Al-4V substrate in air at the temperature ranging from 400–600°C and time from 25–60...

Energy is an essential ingredient for socio-economic development and economic growth of a country. Energy is available in two different forms, fast depleting or non-renewable (coal, fuel, natural gas) and renewable (solar, wind, hydro etc). Wind is one of the potential renewable energy sources...
