CREATING SURFACE LAYERS OF PARTS WITH INCREASED TRIBOLOGICAL CHARACTERISTICS USING COLD GAS-DYNAMIC SPRAYING

One of the transitions to path intensification production processes is perceptibly low stability details nodes in possession these processes. The stamina small, vindictive, nasampered, rubbing pairs, especially quiet, which works out significant tensions aggressive middles. wear upper balls parts can ruin possession, leads waste energy and material resources. ways solve problem creation functional coatings on surfaces that are resistant environments. results analysis antifriction properties materials containing copper, tin, lead, aluminum, polymers presented. advantages disadvantages question shown possibility their application surface using cold gas dynamic spraying. use liquid solid as lubricants analyzed. Attention paid with a crystalline structure similar graphite, known 2D structures (two-dimensional materials)." most studied MoS2 carbon-based compounds, including graphene graphite. diagram interaction sliding surfaces, molecular deformation, wear, bonding, thermal effect, environmental influence shown. It noted be carried gas-dynamic Found compared substrate AA7075, coefficient friction spray coating crystal copper-graphite powder was reduced by 47% - 62%. Rubber composite made mechanical mixture aluminum A30-01 copper C01-00. dependence coefficients spraying content sprayed obtained. until it reaches 61%. At higher concentrations (more than 66%) mixtures coincide.
