Experimental study regarding electrostatic spray coating of solid lubricant for gears

摘要

The paper refers to some investigations in electrical spray coating of solid lubricant. The materials used were combinations of polyester and molybdenum disulfide or graphite in various proportions. Aspects of behavior of the coating and friction coefficient for polyurethane/MoS2 and polyurethane/graphite coatings were studied. Experiments for endurance tests (multifactorial plan 33) were performed in order to evaluate the performances of polyurethane/MoS2 and polyurethane/graphite coatings. The conclusions of the experiment permitted the optimization of the input parameters by economical reasons for changing the design and the technologies of powertrains for low power and speed in industry.
