By using analytical correlations derived as a result of theoretical research, a computer algorithm has been worked out for simulating the functions of the plough body and the forces exerted by soil upon the operating parts, as well as its draft resistance. These correlations allow to determine the draft resistance of the plough depending on the parameters of its body, as well as to evaluate the...
We demonstrate the capability of optical coherence tomography (OCT) to perform topography of metallic surfaces after being subjected to ductile or brittle fracturing. Two steel samples, OL 37 and OL 52, and an antifriction Sn-Sb-Cu alloy were analyzed. Using an in-house-built swept source OCT system, height profiles were generated for the surfaces of the two samples. Based on such profiles, it ...
Polymeric composites (PC) of tribological applications with a high level physical, mechanical and thermal properties based on aromatic polyamide silica gel have been developed. Regularities obtained that describe the effect filler content in PC friction coefficient, temperature surface intensity linear wear rate studied PC-steel pair. It was found optimal polymer matrix is 10 wt %. The morpholo...
Nanoparticles have as characteristics super sliding, extreme pressure, self-healing, etc., which can improve the friction reduction and anti-wear performance of sliding components, when used lubricating oil additives. Nano-copper particles a good synergistic effect with other antifriction agents, antioxidants grease additives because their low shear strength grain boundary slip effect, showing ...
This research reports the antifriction and antiwear properties of Mn3O4-Graphene nanocomposites (Mn3O4-G) as additives a paraffinic base oil commonly used in formulation electric vehicles transmission oils, G-III oil. Four nanodispersions have been designed, + 0.025 wt% Mn3O4-G, 0.050 0.075 Mn3O4-G 0.100 to know optimal concentration nanoadditive. Tribological experiments were carried out with ...
