Silicon carbide (SiC) is widely used to improve the non-linear conductivity of resistive field grading composite. In this paper, SiC nanoparticles are modified into core-shell with silica (SiO2) coating on surface and characterised by transmission electron microscopy X-ray diffraction, respectively. The 7 wt% [email protected]2/epoxy nanocomposite then prepared, pure epoxy SiC/epoxy prepared as...

In this study, the effect of surface roughness and roughness morphology on the bond strength of WC-Co-Cr coatings has investigated. The three different surfaces morphology are use for this purpose. The first and tow samples sandblasted with alumina and silicon carbide respectively. Other sample no sandblasted before spraying process. The same WC-10Co-4Cr coating deposited on the substrates with...

Organic coatings act as a barrier to a corrosive solution and check the transfer of electrical charge from the corrosive solution. High performance organic paint systems were applied on plain carbon steel substrate with two different primers viz., epoxy Zn phosphate and epoxy Zn rich. Identical intermediate and top coats were applied on them having equal dry film thickness. Both uncontrolled lo...

Polymer modified fillers in composites has attracted the attention of numerous researchers. These fillers are composed of core-shell structures that exhibit enhanced physical and chemical properties that are associated with shell surface control and encapsulated core materials. In this study, we have described an apt method to prepare polyimide (PI)-modified aluminum nitride (AlN) fillers, AlN@...

This research investigated the usage of cuprous oxide powder as filler for epoxy in marine coating industries. The basic formulation consist powder, pre-polymer, and curing agent. main manipulation variable this is quantity added into resin, which varies from 2, 5, 7, 9, 11 per hundred gram resin (phr). Polyether (amine) was used agent at equivalent molar ratio. Mechanical stirring to achieve d...

We investigate in this work the formulation of composite resistive pastes based on epoxy resins and graphite for micro-heater manufacturing via thick-film technology. These resistive pastes are designed for screenprinting onto a printed circuit board (PCB) substrate; further coating with expandable polydimethylsiloxane (PDMS), a composite based on an elastomeric matrix and expandable microspher...
