The Influence of Physicochemical and Structural Properties of Polymetallorganosiloxanes on their Tribotechnical Characteristics

Abstract:

The effect of molecular structure and physicochemical parameters of polymetalphenylsiloxanes in a solid state on their tribotechnical properties has been investigated. Characteristics of polymetalphenylsiloxanes (PMPS) have been determined by means of physicochemical methods. Inner structure of a solid phase of PMPS has been examined by means of positron annihilation spectroscopy (PAS). Minimal sizes of ordered (matrix) and disordered (voids) regions were calculated based on the obtained PAS data. Specific polarizing potentials responsible for the stability of PMPS spherical particles have been calculated based on physicochemical parameters.
