Abstract:
The effect of tape surface roughness on the head-tape interface is investigated for typical head contours using tapes with different surface roughness characteristics. Intensity-based monochromatic interferometry is used to obtain the asperity compliance curves for tapes of different roughness by relating contact pressure to the spacing between the head and the tape. A parabolic model and the Greenwood-Williamson model for contact between rough surfaces are used to “curve fit” experimental results for contact pressure versus spacing, and numerical calculations for the head-tape spacing of a cy

Abstract:
The early stages of surface oxidation of biaxially textured Ni–W tapes were studied using thermodynamic calculations along with experimental tape oxidation at low P(O2). Tape phase and chemical composition, surface morphology, and roughness were examined using x-ray diffraction (XRD), energy-dispersive x-ray analysis (EDX), secondary ion mass spectroscopy (SIMS), x-ray photoelectron spectroscopy (XPS), and atomic force microscopy (AFM). For a Ni0.95W0.05 alloy tape, the precise position of the tape oxidation line in P(O2)–T coordinates was established. This line includes a break at T ≈ 650 °C

Abstract:
Surface roughness-induced hydrodynamic gas lubrication theory including rarefaction effects is used to explain the effects of surface roughness on the magnetic head-medium spacing. Since video-recording operates at h/σ (film thickness/standard deviations of composite roughness) ≤ 3, the spacing increases with the roughness because the head surface remains at the distance on the order of 3σ from the mean of the tape surface. Data processing tapes operate at h/σ ≥ 4, and the increase in spacing with the roughness is found to be due to roughness-induced squeeze films. Squeeze motion can be genera

Abstract:
Very thin head-tape spacing, combining contact and floating conditions, is investigated for high density magnetic recording. A generalized lubrication equation, based on a linearized Boltzmann equation, is coupled with the tape deformation equation for analysis. Tape-surface roughness is also taken into account in the lubrication equation. The average flow model is adopted to analyzing tape-surface roughness. For very thin spacing conditions, it is found that the spacing based on the linearized Boltzmann equation is smaller than that based on first-order slip flow, and larger than that based o

Abstract:
The grindactivity of wheel is remarkably lost by the loading of wheel surface in dry grinding of hard carbon parts. In this report, we propose the dressless wheel treatment, in which loading chips are removed with adhesive tape, and experimentally investigate its effect on recovery of grindactivity, analyzing the stock removal, the grinding current and the surface roughness in repeat of grinding cycle with treated and non-treated wheels. The removal and finishing performances of loaded wheel are recovered by the dressless wheel treatment.

Abstract:
A thin ScSZ electrolyte with a large area was synthesized using the tape-casting method. The conductivity of 0.095 S cm-1 at 800°C was achieved. The maximum power density of a single cell reached 368 mW cm-1 at 800°C. To make a large electrolyte battery more suitable, our study improves the casting method of preparing a dense, porous electrolyte substrate that promotes surface roughness of the electrolyte. However, it is difficult to control the thickness of the substrate, meaning that further improvements are needed.

Abstract:
This paper presents the design and experimental verification of the Risø-B1 airfoil family for MW-size wind turbines with variable speed and pitch control. Seven airfoils were designed with thickness-to-chord ratios between 15% and 53% to cover the entire span of a wind turbine blade. The airfoils were designed to have high maximum lift and high design lift to allow a slender flexible blade while maintaining high aerodynamic efficiency. The design was carried out with a Risø in-house multi disciplinary optimization tool. Wind tunnel testing was done for Risø-B1-18 and Risø-B1-24 in the VELUX w

Abstract:
As magnetic tape or other web-like material is wound onto a roll, air moving with the incoming stream and the roll becomes forced into the converging wedge at the stream’s point of tangency. The spiral-shaped air bearing so formed can extend many wraps into the roll’s interior. When the roll is subsequently brought to rest, the entrained air discharges from it, and the roll’s radius gradually decreases until all adjacent tape layers have come into direct contact. In the present paper, a model is developed for this transient discharge process, and for the rate at which the roll stabilizes follo

Abstract:
Multilayer ceramics technology, as LTCC, offers several advantages for the fabrication of miniaturized three-dimensional structures, e.g. for microsystem applications, where electrical, mechanical and fluidic functions can be combined in robust and compact packages. 3D features, required by those applications, are e.g. vias for electrical and thermal interconnection, cavities for chip integration and channels for fluidic functions. They can be realized, in principle, in the sintered, as well as in the green state, but structuring in the green state dominates due to the then far better machinab

A noncontact three-dimensional optical profiler for measuring surface roughness is described. The system consists of a reflection microscope, Mirau interferometer with a reference surface mounted on a piezoelectric transducer, CID detector array, frame grabber, and micro-computer. Interferometric phase-shifting techniques are used to obtain surface height information. The height measurements are processed by a computer to obtain topographical statistical parameters, which are useful in predicting tribological and magnetic performances of the head-media interface in magnetic storage systems.

Every layer's surface morphology was observed by scanning electron microscopy. The seed layer Y 2 O 3 film was full coverage of the NiW substrate. The cap layer CeO 2 showed a smooth and crack-free surface and good crystallinity. The roughness of CeO 2 surface was measured by atom force microscopy. The transmission electron microscopy was used to analyze the cross-section of buffer layers and YBCO layer.

Suitable dispersion media and additives can usually be found for powder of any chemical composition to be deposited by EPD, providing the particle size and size distribution, and their surface to volume ratio are suitable.

The results of research related to the influence of partially regular microrelief parameters on the adhesion component of the friction factor under boundary lubrication are presented. It has been shown that micro grooves are effective under boundary friction on precision surfaces with low roughness when lack of film and probability of seizure appear. The deformation component of the friction force of surfaces with micro grooves has been studied. The time of micro running-in was the key factor while assessing the dependence of the deformation component on friction when taking into account the d
