  • Tribological characteristics of lithium disilicate glass substrates media
    The surface topography and surface roughness of the finished disks were characterized using an Atomic Force Microscopy(AFM) and a Tencor P-2 profilometer . three parameters: texturing Ra, center to peak(Rp), and the bearing-ratio( tp ) 50A below the...
  • Gap Conductance and Temperature Transients in Modified Pulse Design Experiments
    Several pairs of these specimens were ground to the desired thickness in a manner produc- ing a nondirectional finish and were designated as (interfacial surface morphology)-ISM-I, ISM-II, and ISM-1II. The Talysurf-4 profilometer measurements of the U02 specimens surface roughness gave center- line averages (CLAs) of... However, for most of the MPD surfaces, tp > 0 .

The surface roughness (Rz, Ra, Sm, tp ) was measured by a Mod. 170311 profilograph– profilometer (Kalibr plant, Russia) and a Talysurf 5 device (Rank Taylor Hobson, UK).
  • Experimental study on operating temperature in laser-assisted milling of silicon nitride ceramics
    ...Vc=1.0 m/s, DOC=0.2 mm; case a, Pl=300 W, tp =15 s; case... Surface roughness—Figure 19 provides the machined surfaces under these three cases. The surface roughness Ra was evaluated with a Suftest-402 surface profilometer (Mitutoyo Corporation). It can be seen that with high operating temperature good surface finish can be obtained.

This range of feed covers typical finishing and roughing operations of production machining processes such as milling... The same cutoff length and scanning distance were used in profiling as were with the surface profilometer .
    The roughness of the test surface is varied for four different levels by finishing the surface with different grade of emery papers of #120,#280, #600 and #7000. The roughness of the polished surface, as measured along one polishing line by profilometer , is given in... ...t:a L : $4 1 Q 0 EI : $$ 2 8 0 @ : Tp 6 0 0...
