Then Reebok gave the shoes to the Boston College football team for wear-testing, and when they got the shoes back they found out that all the football players had cut out the rubber component with scissors.
Figure 1 Schematic of pin-on-disk wear-testing apparatus.
Dynamic mechanical analysis and wear-testing results indicated that CNFs treated with such thick silane coatings are effective nanofillers for enhancing mechanical and tribological properties for polyethylene.
Optimum fusing conditions (time and temperature) for wear-testing sample were investigated in terms of microhardness and porosity of the coatings.
Constituent phases, microstructure, microhardness and wear resistance of aluminum bronze coatings with different Fe and Ni contents were investigated using XRD, OM, SEM, EDS, microhardness tester and pin-on-disk wear-testing machine, respectively.
Conditions of the four-ball wear tests are 600 rpm (spindle speed), 392 N (loads), and 1 h (testing time).
The characterization included: scratch testing, wear testing+optical profilometry, microhardness, optical microscopy and X-ray diffraction.
In conjunction with kinematic data, accurate tibiofemoral force data may be used to design more effective knee-testing rigs and wear simulators.
Several wear failure modes, such as micro-plowing and pits, were identified in the post-testing analysis.
The first follow-up survey of registrants, conducted in 2007, includes questions on type(s) of masks or respirators worn, training, access to fit-testing, qualitative fit-checking, and respirator maintenance.
