  • Friction Testers and Wear Testers
    Friction testers determine the coefficient of friction or the friction force. Additionally, they measure the resisting force tangential to the interface between two bodies when under the action of an external force, one body moves or tend to move relative to the other. Wear testers evaluate
  • Medical Device Link .
    with light-emitting-diode indicators, a programmable logic controller, and an RS-232 communications port. Coefficient-of-friction tester displays results in real time Data acquisition software can display coefficient-of-friction results in real time. The software also allows users to alter sled

  • Quality Control of Minidisk Polymer Topcoat Using Nano Scratch Tester and Tribometer
    picture of how the coating will perform in service conditions. Fig. 1 shows typical Tribometer traces for two polycarbonate thin films where a rapid rise in friction can be taken as a measure of coating breakdown under load. Nano Scratch data is presented in Fig. 2 where two distinct critical failure
  • Lubrication of Gears (.pdf)
    The purpose of lubricating gears is as follows: 1. Promote sliding between teeth to reduce the. coefficient of friction (m). 2. Limit the temperature rise caused by rolling. and sliding friction. To avoid difficulties such as tooth wear and premature failure, the correct lubricant must be chosen
  • Pharmaceutical Powders Small Sample Sizes Yield Big Results
    in test results. The same results given by the larger 263cc shear cell (flow function, bulk density, arching dimension, internal friction angle, rat-hole diameter) are given with the small volume shear cell. The small volume shear cell does have an additional advantage over the larger 263cc shear cell
  • A Cure for Hammer Rash: Measuring Powder Flowability with Shear Cell Testing
    , the pow-. der’s wall friction (that is, its ability to move against the. hopper surface) must be below a critical value. The pow-. der discharge must also be controlled by a valve or feeder. that allows powder to flow through the outlet’s entire. cross-sectional area. In fact, the failure to allow flow
  • Processing Milk Powder - The Flowability Challenge
    sample, then shear the powder against itself to measure the amount of friction that will cause resistance to movement. This type of test gives several pieces of information that can be useful, such as flow function and density. Figure 2 shows a typical report that characterizes various blends of milk
  • Medical Device Link .
    strength, static and kinetic friction, tensile energy, and compression measurements. Thwing-Albert Instrument Co., 10960 Dutton Rd., Philadelphia, PA 19154. Tensile test system A 0 500-lb tensile, cycle, and compression test system is suitable for testing adhesives, fiber, composites, ceramics
  • Surface Enhancements Eliminate ESD Damage During Operation of State-of-the-Art I.C. Handlers
    and performance of key Exatron handler components such as precision trackwork, main plates, extrusions, input & output mechanisms, rails and slides. All these metal surfaces are subjected to potentially severe friction from the constant action of plastic and ceramic I.C.s being run through testing cycles. Surface
