    Effect Of Sand Blasting On Soda Lime Glass Properties حسب Bousbaa, C.

    منشور في 2003
    "…The average strength remains almost constant while the dispersion becomes much reduced for the glass sand blasted during 60 minutes (m = 10.4 and smoy = 64 MPa). The variation of the relative efficiency of glass protected solar panels versus sand blasting duration (seen up to 300 min) shows a slow regular decrease until 0.91 for a 90° impact angle and until 0.95 for 30°. …"

    High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling حسب Cabibbo, Marcello

    منشور في 2014
    "…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …"
