High pressure is very effective tool for research of discovering new phenomena and of exploring new materials. For example, some materials undergo superconducting transition under high pressure. Also, it is well known that some insulators become metallic at high pressure. Conversely, there are some singular materials in which metallic state becomes unstable for insulating state at high pressure...
The results of the investigations into the technological formation of new wear-resistant polymer composites based on polytetrafluoroethylene (PTFE) filled with disperse synthetic and natural compounds are presented. The efficiency of using PTFE composites reinforced with carbon fibers depends on many factors, which influence the significant improvement of physicomechanical characteristics. The ...
A study was carried out to characterize Ni-Co-PVC and Ni-Cu-PVC composite materials prepared by mechanical alloying technique (MAT) using SEM, EDS and electrochemical test. Composite materials were prepared by mixing together 95% of metal powder (Ni+Co or Ni+Cu) with 5% PVC. PVC was used as a binder and tetrahydrofuran (THF) was used as a solvent in composite material preparation. Based on the ...
