Development and Performance Evaluation of Self-Lubricating Nanostructured Coatings

In this present work, self-lubricating characteristics of air plasma spray (APS) and high velocity oxy-fuel (HVOF) coatings obtained from reduced graphene oxide doped nanostructured tungsten carbide-cobalt feedstock powders will be investigated. The microstructural, mechanical and self-lubricating wear resistance characteristics of the deposited coatings at optimized spray parameters will be considered for investigation. The present project proposal aims for the development of self- lubricating and high wear-resistant coatings from reduced graphene oxide doped nanostructured tungsten carbide-cobalt and alumina titania ceramic powders. As we know, wear occurs when two solid surfaces which are in contact rub down with each other and it results in the removal of more material from the soft surface than the harder one. When the material is removed from the outer surface of an engineering component, it fails in satisfying the service requirements and hence complete component has to be replaced with a new one which is very expensive some times. Therefore, to improve surface properties like higher hardness, wear resistance, corrosion resistance, etc., thick hard surface coatings are deposited on many engineering components using cold spraying technology which is economical as compared to other thermal spray technologies. The project has an immense commercial application.

Development of Welding Technique to avoid the Sensitization in the Alloy 600 by Conventional Gas Tungsten Arc Welding Method: Alloy 600 is a highly corrosion resistance Nickel based superalloy developed for high-temperature applications. The presence of Chromium (Cr) and Iron (Fe) in alloy 600 provides an excellent corrosion resistance in the service environment. The segregation of alloying element Cr during solidification ends up with Cr-depleted zones in the grain boundaries regions. There is a constant demand for the reduction of Cr-depleted zones in the materials for various applications. In the view of this, the present study investigates the possibility to avoid the sensitization by employing different filler wires. In order to achieve this, the weld joints were fabricated by Gas Tungsten Arc Welding (GTAW) and Pulsed Current Gas Tungsten Arc Welding (PCGTAW) with ERNiCr-3, ERNiCrMo-3, and ERNiCrMo-14 filler wires.

Carbon Emission in a Three-Echelon Supply Chain Production Distribution Planning Model with Stochastic Demands: The main aim of this project is to develop a stochastic production distribution network model with multiple distribution centers, production sites and suppliers that incorporate carbon emissions in the context of a three-echelon supply chain. The considered model is a capacitated facility location model were simultaneously making of location-location decisions and developing of a distribution strategy is a challenging task. The carbon emissions considered in the chain are associated with the decision of manufacturing of products, transportation of items from suppliers to open plants and plants to open warehouses and inventory positioning of different products in different stages of the supply chain.
