High-density polyethylene (HDPE) was compounded with untreated and surface-treated mica (10,20,40 wt %) and composites were injection-molded. The composites were radiation crosslinked (100, 300, 700 kGy) and hydrocarbon permeability, tensile impact strength, and tensile strength at 25 and 80Β°C of th

Abstract
Thin polymeric films were deposited from siloxane plasma on the surface of polyethylene. The surface composition of the films was measured by Xβray photoelectron spectroscopy (XPS) and the permeability to O~2~ by an analytic gas permeability fractometer. No significant improvement of barrier to O~2~ was observed with 200 nmβthick coatings. When the siloxane layer was subjected to a further O~2~ plasma treatment, a threefold decrease of permeability to oxygen was recorded. Results are discussed on the light of the effect of the O~2~ plasma on the siloxane backbone. Β© 1993 John Wiley & Sons, Inc.

## Abstract The microstructural change, crack initiation and spallation of a vacuum plasma sprayed (VPS) thermal barrier coating on an INCONELβ738 superalloy substrate were investigated after successive 300 h thermal cycles at 1050Β°C. The coating was characterised using Raman spectroscopy, scanning
The shuttle heat transfer is one of the reasons reducing the performance of Stirling engines. This study is concerned with the reduction in shuttle heat transfer by coating the displacer. The displacer of a gamma type Stirling engine was coated with a layer of yttria-stabilized zirconia (YSZ), and t
