Abstract

The article presents studies on the possibility of using a heavy fraction of coke-chemical resin as a macrocomponent of cladding lubricant, its reducing properties for obtaining copper powder and protecting it from oxidation under the influence of temperature and oxygen in the air. All experiments were carried out using a thermal weighing unit consisting of a vertical tubular furnace, electronic scales. To obtain the kinetic characteristics of the pyrolysis of the resin of JSC "Shubarkulkomir", the dependencies of velocity on time at different temperatures were constructed. The values of the activation energy through the rate constant of the processes for different periods of removal of fractions are calculated. Based on these calculations, mathematical models of the removal of fractions of different periods at 200 and 257 °C. are obtained. To determine the temperature onset and the interval of complete reduction of copper oxide, curves of interaction of the charge components were obtained on a derivatograph (Model: Q-1500D; Manufactured by Paulik and Erdei, Hungary). At the rate of non-isothermal heating of the charge equal to 10 °/min, complete recovery of copper is achieved in the temperature range of 100-360 °C and within 26 min. Further, the resulting copper powder was tested as a composite material. Samples for testing composite powders based on a mixture of copper were made of 45 with a hardness of HRC 40-42. dimensions l x b x h = 10 x 10 x 10 mm. All samples had surfaces of class 8 roughness according to GOST 2789. The control bodies were rollers with d = 40 mm, 15 mm thick, made of 45 steel (GOST 1050) with a hardness of HRC 35-40. Based on the results obtained, it can be assumed that the finest copper films were obtained in the friction pair node, which contributed to a significant improvement in the basic tribotechnical parameters of the tested oil after the introduction of the developed antifriction composites into it.
Results of this study have been obtained in laboratory of Branch “Zh. Abishev chemical-metallurgical institute” of RSE “National Center on complex processing of mineral raw materials of the Republic of Kazakhstan” of Ministry of industry and new technologies of the Republic of Kazakhstan within the framework of the scientific and technical project “Technology of producing the anti-friction composites with the high thermal and physical characteristics”.
