Solution Precursor Plasma Spray (SPPS) technique is an emergent technique which offers significant performance advantages with various functional coatings like YSZ, ZnFe2O4, LSM, metal-doped ZnO, etc. Apart from the above capabilities, efforts towards development of an innovative hybrid approach through simultaneous deposition of powder and solution resulted in coatings with unique microstructu...

In the present work, six-layered (Zirconia/Nickel) functionally graded materials were fabricated via powder metallurgy technique (PMT). The microstructure, fracture surface and the elemental analysis of the prepared components were studied, and their linear shrinkage, electrical conductivity, fracture toughness and Vickers hardness were evaluated. The results show that the linear shrinkage of t...

This paper deals with production of hard metal by powder metallurgy and its effect on the environment. Hard is a composite material that consists tungsten carbide as refractory phase cobalt or nickel soft binder phase. It cannot be produced classical casting technology. Owing to excellent properties, such high hardness, wear heat resistance etc., can applied in variety industrial fields. Powder...

A description of the important physical metallurgy aspects of Ni3Al and NiAl encompassing structure, crystallographic defects, slip systems and phase stability has been presented in this article. The microstructures generated in the two alloys by conventional as well as novel processing techniques have been discussed. The effect of alloying additions on the microstructure has been enumerated. B...
