The discharge of heavy metals into aquatic ecosystems has become a matter of concern in India over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. Industrialization in India gained a momentum with initiation of five year developmental plan in the early 50's. The pollutants of concern include lead, chromiu...

Saturation diffusion with chromium has not been adequately studied among all the surface thermochemical treatment (STCT) processes of steels. Especially, complex saturation behavior when several elements are added directly for chemical needs to be systematically studied. This work aims at determining effect V, Mo, and Co on parameters thermal (thickness, phase composition, microstructure, micro...
