Effect Of Electron Irradiation On Mechanical, Tribological And Thermal Properties Of Polytetrafluoroethylene, K. D. Ormanbekov, B. K. Rakhadilov, A. Zh. Zhassulan, N. E. Mukhamedov, A. B. Shynarbek, N. M. Magazov

Eurasian Journal of Physics and Functional Materials

The article presents the study results of the electron irradiation effect on the mechanical, tribological and thermal properties of polytetrafluoroethylene (PTFE). The results allow a better understanding of the processes occurring in the structure of PTFE under irradiation and reveal potential applications of the modified material with improved tribological characteristics, high thermal resistance and mechanical strength. In this work the samples were tested for wear resistance and thermal stability. It was found that the effect of electron irradiation leads to a significant increase in the microhardness of the material by 1.5 times compared to the initial state. However, degradation of …


Effect Of Inhibitor On Electrochemical Behavior Of 1cr18 Stainless Steel In Acidic Solution Under Friction, Jinping Xiong May 1999

Effect Of Inhibitor On Electrochemical Behavior Of 1cr18 Stainless Steel In Acidic Solution Under Friction, Jinping Xiong

Journal of Electrochemistry

The electrochemical behavior of 1Cr18 stainless steel had been studied using a reciprocating triboelectrochemical equipment under friction in 0.2 mol/L H2SO4 solution with and without addition of thiourea, the frictionized surface of 1Cr18 stainless steel had been examined by the SEM, XPS and IR. The results showed that the loss rate of 1Cr18 stainless steel in the solution could be reduced by addition of thiourea. The adsorption of thiourea on the surface of 1Cr18 stainless steel prohibited the oxidization of Cr3+ to form Cr() and formation of passive film consisting of CrO42- or/and Cr(), and make the passive range to …
