Antifriction Coatings

New porous films based on polyanionic cellulose with AlOOH nanoparticles have been developed. The morphology of the films has been studied by electron microscopy: the size of the formed pores is 1000-500 microns; the total surface porosity of the films is 30%. Using infrared microscopy, it was shown that during the formation of porous films, their chemical composition remains unchanged. Differential scanning calorimetry was used to determine the threshold for thermal destruction of porous films: 306 С. The possibility of using the obtained materials as antifriction coatings when filling the pores with solid lubricant MoS2 is considered. It is shown that for a steel sample protected by a porous coating with MoS2, the friction coefficient decreases by 50% compared to the friction coefficient for a steel surface under a load of up to 450 MPa.

Physical And Mechanical Characteristics

A modern method of processing steel parts by ion-plasma sputtering in vacuum is proposed as a solution to the problem of friction and wear. An ion-plasma coating based on Ti-Cu has been developed. Such parameters as microhardness, roughness, friction coefficient of the intermetallic, conglomerate and nitride coatings have been studied
