Wear-resistant metal coatings formed by magnetron sputtering on fire-proof fabric materials
Keywords:magnetron sputtering, metal coating, fabric material, adhesion, friction coefficient, friction track width
Purpose. Study of the adhesive strength and wear resistance of metal coatings formed by magnetron sputtering on fire-proof fabric materials.
Methods. Tribological tests were carried out on a JLTB-02 tribometer. The adhesive strength of the coatings was evaluated using a measurement technique using adhesive tape with a lattice notch. The wear tracks on the coatings were examined using a Hitachi S-900 scanning electron microscope.
Findings. The adhesive strength and tribological properties of aluminum and brass coatings deposited by magnetron sputtering on arcelon with various impregnations are investigated. It is determined that the use of impregnation, regardless of the composition, increases the adhesive strength of coatings formed by magnetron sputtering. The influence of both the composition of the chemical impregnation and the coating material on the tribological characteristics of the studied samples has been established. It is established that aluminum coatings are characterized by lower values of the coefficient of friction and the width of the friction tracks than for brass coatings, which indicates their higher wear resistance.
Application field of research. The presented research results can be used in the manufacture of fire-retardant overalls necessary for firefighters, rescuers, as well as for oil and gas industry workers, welders, metallurgists and the military.
