Evaluation of Hot Corrosion Properties for Nano-coated Superalloy

Directive properties of active coated nano - particles

The directivities of the fields radiated by a variety of cylindrical and spherical active coated nano-particles, which are excited by their respective sources of illumination at optical frequencies, are investigated. Particular attention is devoted to the influence of the source location and optical gain constant on the directivities. While significant variations in the directivities are realiz...

Study of a New Type High Strength Ni-Based Superalloy DZ468 with Good Hot Corrosion Resistance

Preparation and corrosion behavior evaluation of amalgam/titania nano composite

BACKGROUND Many attempts have been performed and continued for improvement of dental amalgam properties during last decades. The aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. MATERIALS AND METHODS In this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...

Effect of nitriding temperature on the nanostructure and corrosion properties of Nickel coated 304 stainless steel

Nickel films of 150 nm thickness were deposited on 304 stainless steel and post annealed under flow of nitrogen at different temperatures. The prepared samples were corrosion tested in 1.0 M H2SO4 solution using potentiodynamic polarization technique. Crystallographic and morphological structure of the samples were analysed by X-ray diffraction XRD and atomic force microscopy AFM respectively b...

Effect of Thermomechanical Working on the Microstructure and Mechanical Properties of Hot Pressed Superalloy Inconel 718

Experimental results on hot deformation and dynamic structural processes of nickel based alloy Inconel 718 are reviewed. The focus is the analysis of dynamic precipitation processes which operate during hot deformation of these materials at elevated temperatures. Hot compression tests were performed on the solution treated precipitation hardenable nickel based superalloy Inconel 718 at 720-1150...
