    Nanometrically smooth infrared silicon optics can be manufactured by the diamond turning process. Due to its relatively low density, silicon is an ideal optical material for weight sensitive infrared (IR) applications. ...
  • Durazo-Cardenas, Isidro Sergio; Noguera-Sagrera, Albert; Impey, S. A. (Taylor & Francis, 2014-01-27)
    Samples of polishing effluent produced during infrared optics manufacture were analyzed. Their particle size, composition, Zeta potential, chemical oxygen demand (COD), total suspended solids (TSS), and settleable solids ...
  • Impey, S. A. (Cranfield University, 1989-12)
    Metal loss is an unavoidable consequence of the large scale melting of aluminium and its alloys. The objective of such processing must be to minimise losses, both from an economic viewpoint and to ensure optimum quality ...
  • Wellman, R. G.; Tourmente, H.; Impey, S. A.; Nicholls, J. R. (Elsevier Science B.V., Amsterdam., 2004-11-01)
    Previous studies on the erosion of electron beam physical vapour deposited thermal barrier coatings (EB PVD TBCs) has shown that aging the coatings at between 1100 and 1500 à °C before erosion increases the erosion rate. ...
