DEVELOPMENT OF MATHEMATICAL MODELS DESCRIBING THE PROCESS OF FRICTION AND WEAR OF META-ARAMID

The study aims to describe the properties of heat-resistant coatings of tribological purpose based on meta-aramid and obtain mathematical models, that will provide simple usage of this data. These are results of experiments that show the dependencies of coefficient of friction and mass wear on two factors: load and filler content. All the experimental data is obtained for such filler materials: boron nitride, graphite, molybdenum disulfide. As a result, the number of mathematical equations that describe this experimental data is obtained. These equations allow to get interpolated value for any combination of arguments, present smooth 3D graphs, that show the form and character of all the dependencies.
