Metallization of Porous Polyethylene Using a Wire-Arc Spray Process for Heat Transfer Applications
نویسندگان
چکیده
Metallization of polyethylene (PE) using thermal spray techniques has proved difficult due to its low melting point and softness. In this study, metallic coatings were applied on porous substrates a twin wire-arc process. Commercially available sheets, 3 mm in thickness, used as substrates. Copper (Cu), aluminum (Al), zinc (Zn) successfully deposited the polymer, without prior surface preparation, form with thickness about 400 µm. Coating morphology cross-sections examined scanning electron microscope. Individual metal splats non-porous observed study differences bonding mechanisms. The adhesion strength electrical resistivity PE evaluated. It was found that bond all three be higher than ultimate fracture porous. These results suggest porosity polymer helps overcome challenges metallizing provides significant reduction weight polymer. Therefore, these properties aided fabricating an extremely lightweight, composite material potential use management applications.

متن کاملHeat Transfer in Three-Dimensional Flow along a Porous Plate
An analysis of heat transfer in the flow of a viscous, in-compressible fluid along an infinite porous plate is presented when the plate is subjected to a transverse sinusoidal suction. The flow field becomes three-dimensional due to this type of suction velocity. Expressions for the flow and temperature fields are obtained by series expansion method. It is found during the course of discussion ...

The most important plastic resins used for wire coating are polyvinyl chloride (PVC), nylon, polysulfone, and low-/high-density polyethylene (LDPE/HDPE). In this article, the coating process is performed using elastic-viscous fluid as a coating material for wire coating in a pressure type coating die. The elastic-viscous fluid is electrically conducted in the presence of an applied magnetic fie...
