چکیده
Abstract In this study, the tribological properties of fused deposition modelling (FDM) 3D printed Polylactic Acid (PLA) is studied when it slides against a steel disk at various speeds. pins were using PRUSA MINI+ Printer according to recommended printing parameters. Pin on disc tests conducted normal load 20 N, sliding time minutes, and linear speeds 0.46, 0.58, 0.7 0.81 m/s . Experiment results showed that wear rate increases with increase speed, coefficient friction decreases in speed. Observation worn surfaces suggested major mechanisms are abrasion, adhesion, delamination. The difference behaviour was mainly caused by hardness-temperature relationship. main anomaly occurred observed trends pin melted highest resulting opposite trends. temperature contact point weakens PLA pins. Therefore, can be used temperature-controlled low speed application such as lubricated gear not for applications subjected high temperature.

متن کاملFriction and wear behaviour of tool steels sliding against 22MnB5 steel
Boron steels are used in hot stamping process due to their good mechanical properties. During the stamping process, the dies are exposed to aggressive conditions including adhesive wear, abrasion, thermal stresses and fatigue. In the present work, QRO 90 and UNIMAX slid against 22MnB5 steel in four conditions: with and without hardening treatment and, with and without Al–10%Si coating, in order...

Artificially fabricated surface textures can significantly improve the friction and wear resistance of a tribological contact. Recently, this surface texturing technique has been applied to polymer materials to improve their tribological performance. However, the wear behavior of textured tribo-pairs made of steel and polymer materials has been less thoroughly investigated and is not well under...

Vaginal dilation is proposed as the first choice treatment for patients with vaginal aplasia, but many patients with MRKH or Rokitansky syndrome (and cases with CAIS) may require a vaginoplasty. It is also necessary to make vaginoplasty in patients with vaginal or cervicovaginal atresia with a functional uterus before performing an utero-neovaginal anastomosis, also in trans-sexual men.

The chemical inertness, high melting point, and intrinsic lubricity of polytetrafluoroethylene PTFE have been used to develop solid lubricating parts for operation in extreme environments, from frying pans to satellites. The atomic-level mechanisms associated with friction and wear at PTFE surfaces are elucidated here by systematic investigations of the frictional anisotropy measured with respe...
