Electrostatic spray deposition (ESD) of polymeric powders on thermoplastic (PA66) substrate

Hydroxyapatite/silica Nanopowders Deposition on Ti Substrate by Plasma Spray Method

In this work, hydroxyapatite/silica nanopowders were granulated to fabricate plasma sprayable feedstocks. For this purpose, the wet powders obtained by heating a hydroxyapatite/silica slurry were stirred and sieved. To realize the feedstock application in the plasma spray process, powders were deposited on titanium substrate. The morphology of granulated feedstock and sprayed coating was ...

EFFECTS OF SUBSTRATE TEMPERATURE ON THE STRUCTURAL PROPERTIES OF ZnO:Al THIN FILM DEPOSITED BY ELECTROSTATIC SPRAY DEPOSITION

Zinc Oxide and Al-doped ZnO (AZO) thin films were prepared by Electrostatic spray deposition method on soda lime, glass substrates. The effects of substrate temperatures (300, 350, 400 and 450 C) on the Structural properties of the films were investigated. X-ray diffraction analysis indicates that the films were polycrystalline, having hexagonal (Wurtzite) structure irrespective of their substr...

Development of Passivated Pyrophoric Metal Powders (hafnium and Zirconium) with Reduced Electrostatic Discharge (esd) Sensitivity

High-density metals such as hafnium and zirconium are of interest to the propellant, explosive, and pyrotechnic industry due to their high oxidation enthalpies; however, these metal fuels suffer from electrostatic discharge (ESD) complications creating safety concerns. Previous attempts to passivate these powders have failed due to abrasion of the protective coatings. Two novel methods for dese...

Cold Spray Deposition of SS316L Powders on Al5052 Substrates and Their Potential Using for Biomedical Applications

The corrosion behaviour of 316L stainless steel coatings obtained by cold spray method was investigated in this study. 316L powders were deposited onto Al5052 aluminum substrates. The coatings were produced using nitrogen (N2) process gas. In order to further improve the corrosion and mechanical properties of the coatings, heat treatment was applied at 250 and 750 °C. The corrosion performances...
