Different from the variation trend in friction coefficient with the increase of temperature, the specific wear rate of PEEK increases dramatically at low temperature (<150[degrees]C).
Simulations were performed using the friction coefficient determined through equation (10) with a [[micro].

Results in Figure 4 indicate that the DP600 tested with the prephosphate coating has a much lower friction coefficient than that tested without the prephosphate coating regardless of the die temperatures.
The friction coefficient behavior can be categorized into three characteristic regions the evolution of the friction versus time in these contacts.
Thus, 50 teeth yielded 300 dentine and 300 enamel measurements of nanohardness and the elastic modulus as well as 100 measurements of the friction coefficient.
Thirdly, shear stresses between the steel casing and infilled concrete are modeled by friction, which is specified by a friction coefficient defined in GAP elements.
Furthermore, this test confirmed that the friction coefficient depends on the value of surface roughness, as shown Fig.
In this paper, an online identification method which can simultaneously identify three mechanical parameters (the moment of inertia of the system, the viscous friction coefficient of the motor, and the load torque) and a distinctive autotuning speed control scheme are proposed, which adjusts the speed loop parameters using the identified parameters.
