A Study of the Wear Mechanism of Composites Modified with Silicate Filler
The article considers the effect of a filler based on synthetic wollastonite (CaSiO<sub>3</sub>), which is introduced into a polymer matrix made of ultra-high molecular weight polyethylene, on the tribotechnical parameters of the produced polymer composite material. Behavioral features o...

| description | The article considers the effect of a filler based on synthetic wollastonite (CaSiO<sub>3</sub>), which is introduced into a polymer matrix made of ultra-high molecular weight polyethylene, on the tribotechnical parameters of the produced polymer composite material. Behavioral features of composites after friction were investigated by infrared spectroscopy and scanning electron microscopy. It was found that the introduction of wollastonite into the polymer matrix contributed to a reduction in the friction coefficient by 23% and the wear rate by four times. In the micrographs of the friction surfaces of the obtained composite, the formation of new secondary structures oriented along the friction direction, different from the initial polymer matrix, was revealed. The presence of wear products (oxidized polymer groups) and CaSiO<sub>3</sub> on the friction surfaces was recorded by infrared spectroscopy. It was established that the synthesized CaSiO<sub>3</sub> particles were deformed under the action of shear forces and participated in tribochemical processes. |
