And Function

Glass fracture and changes in bending load were investigated by the quasi-static loading method which is characterized by holding a fixed time at each displacement level and incrementally applying displacement. Holding time at each step was 60 s and the incremental displacement was 0.02 mm as the load condition. Ordinary soda-lime-silicate float glass of 50 × 10 × 4 mm was used as the specimen. The glass fracture occurred as the bending load decreased with time, which might be explained using the occurrence of time-dependent fracture and function as a viscoelastic property even at room temperature. Fracture properties of alumina ceramics have the possibility to be closer to float glass than silicon carbide which is called general ceramics.

And Function

Low-emissivity (low-E) and solarcontrol coatings increase the energy efficiency of clear float soda-lime-silicate glass for architectural and automotive window applications. At the same time, coated glass largely maintains its neutral color and high visible transmittance. Two major classes of coated products are currently available for the architectural market: The more durable chemicalvapor- deposition (CVD) coatings are deposited on float glass as it is formed. The vacuum deposited low-E coatings, which are the subject of this article, have superior spectral performance and are deposited off-line by the sputter-deposition process. Many elements of this subjecthave been discussed in the literature, covering energy efficiency for windows, specific examples of low-E coating, a J2 6 brief outline of the deposition techniques, and a more detailed account of optical design considerations for low-E thin-film coatings, particularly for single metal-layer systems. This article briefly discusses aspects of these coatings that relate to their design, performance, and preparation. More attention is given to the materials that constitute the different layers of these coatings and to their specific properties and function.

This paper presents the results of an experimental investigation of fretting wear characteristics on the contact surface of press-fitted shaft subjected to a cyclic bending load. A series of interrupted fretting wear tests with press-fitted specimens were carried out by using a rotating bending fatigue test machine. The evolution of contact surface profile of press-fitted shaft due to fretting wear were measured with a profilometer. The local wear coefficient during the running-in period is discussed from experimental results and FE analysis. It is found that the maximum depth of fretting wear by repeated slip between shaft and boss occurred at the close of contact edge at the early stage of fatigue life and the regions of worn surface are expanded to the inner side of contact edge as increasing number of fatigue cycles. The initial fretting wear rate at the early stage of fatigue life increased rapidly at all loading condition. After steep increasing, the increase of wear rate is nearly constant in the low bending load condition. The local wear coefficient in running-in period decrease dramatically at the early stage of fretting wear.

Transparent conductive ITO films were fabricated on soda lime float glass substrate by colloid dip-coating technique from indium metal ingots and hydrous tin(IV) chloride. It was systematically studied that the effect of the electrical, the structure and optical properties of the ITO doped Sn in quantitative change and different heat-treating process by XRD, UV-VIS spectrophotometer and four-probe instrument. The results indicated that only cubic In2O3 phase was observed from the X-ray diffraction; with the amount of doped Snincreasing, the sheet resistance of ITO was up to minimumand thenincreased. The sheet resistance value decreased with the increase of the annealing temperature and holding time; the transmissivity of the ITO films was higher than 80% in 550 nm wavelength. The lowest sheet resistance value of ITO film which was 300nm thick was 153 ohms per square, which wasannealed at 600°C for 1h and doped Sn 10% (wt).
