“…It has been reported that failure on polycarbonate surfaces initiates when a critical positive hydrostatic stress is reached [40][41][42]. These critical values can be reached earlier by increasing normal load, decreasing sliding velocities, or increasing temperatures.…”

The Tribological behavior of Polystyrene Crystal disc sliding against a steel 100Cr6 ball with a radius of 5mm over a range of loads (1-5N) and speeds (12.5-63mm/s) was investigated using a ball-on-disc tribometer under unlubricated conditions. All the specimens were used as obtained from injection molding. For this purpose, we monitored the evolution of the friction coefficient and the wear rate as a function of sliding speed and normal load applied. The worn surfaces were examined by Scanning Electron (SEM) and optical microscope. Several wear mechanisms were observed: plastic deformation, abrasion in the track, and adhesion at the edge of the track. The mechanisms were found to depend on speed and load. The wear rate is of the order of 10-2mm3/N.M, which may explain that the wear is of a severe type.

“…With the increasing service depth of UHMWPE and POM in water environment, the research on their water absorption mechanism in deep water environment is urgent. [19][20][21][22][23] The entry of water molecules into POM and UHMWPE from the outside is mainly affected by two factors: (1) Wettability between POM and UHMWPE surface; (2) The ability of water molecules to diffuse inside POM and UHMWPE. Aiming at the problem of water absorption in the application of UHMWPE and POM as friction pair materials in deep water environment.…”

“…Polymer materials have high elasticity, low density, high strength, high toughness, corrosion resistance, excellent self‐lubrication, and machining properties. They can widely replace metals as new sliding friction pair materials and are widely used in aerospace, petrochemical, marine engineering, medical equipment and other fields 1–4 . Especially in a variety of wading engineering equipment (ships, water conservancy and hydropower equipment, drilling platforms, deep‐sea exploration equipment, etc.…”

The water absorption of ultra‐high molecular weight polyethylene (UHMWPE) and polyformaldehyde (POM) in different hydrostatic pressure has been investigated by means of high pressure immerse experiments and molecular dynamics simulation. Experiment results showed that water absorption of UHMWPE and POM tended to decrease with the rise of environmental pressure of water within 0 ~ 3 MPa. Water absorption of POM was far greater than UHMWPE under all kinds of hydraulic pressure. When the pressure is 3 MPa, the water absorption of POM is reduced by about 15.2% compared with that under normal pressure, while that of UHMWPE is reduced by about 41.64%. Simulation results showed that water molecules were bonded with UHMWPE molecular chain by means of Van der Waals force, and water molecules were bonded with POM molecular chain by means of Van der Waals force and hydrogen bonds, which provided potent theoretical support for the water absorption properties of UHMWPE and POM.
