Processing and Characterization of Ni2MnSn FSMABy Ajit Behera, S. C. Mishra
Abstract: Among Ferromagnetic Shape Memory alloys (FSMAs), Ni2MnSn Heusler alloys owing to occurrence of large magnetic field induced strain (> 10%) along with other interesting properties like premartensitic transition, high transformation temperature, large magnetocaloric effect and low stress of twin variant rearrangement. The prominent challenges facing the design and utilization of these specialized alloys are a limited range of operating temperatures, phase transformations that have high sensitivity to variations in composition, …

Dependence of Adhesion Strength of Plasma Spray on Coating Surface PropertiesBy Ajit Behera, S. C. Mishra
Abstract: It is well known that thermal plasma spray coatings have diversified utilizations, but not vividly in use, mainly because of high cost of spray grade powder, for development of thick coating > 50 µm on metal substrates. Present investigation aims at depositing plasma spray coating on metals using low-cost/waste materials. A mixture of fly-ash + 20 weight percent of Quartz + 20 weight percent of illmenite is used for coating …

Application of Neural Network Analysis to Correlate the Properties of Plasma Spray CoatingBy Ajit Behera, S. C. Mishra
Abstract: Thermal spray coatings are more often being demanding process at the recent stages of industrial design processes to become fundamental element of the engineering system. The aim of the present paper is to develop a model-based estimation and control for regulating the coating adhesion strength, by using neural network. This proposed model permits cost reduction by the possibility of adjusting the parameter of the process for each of the desired …

ANN Controlled Plasma Spray Process by using Industrial WasteBy Ajit Behera, P. Parida, R. K. Behera, S. C. Mishra
Abstract: Plasma spray coating process has become a subject of intense research because it becomes an affordable solution for many industrial applications. The present work aims at developing and studying the industrial wastes (Flay-ash powder mixture) as the coating material, which is to be deposited on Mild Steel and Cupper substrates. To increase the coating deposition efficiency and to decrease the cost of coating process, one of the artificial intelligence (AI) …
