One of the main disadvantages of the convective method of drying polymer coatings is their porosity. Porosity during infrared treatment is much less, and the quality of the coatings is significantly higher. However, the analysis of a priori information showed the lack of information about the infrared treatment of polymer coatings during the restoration of the body parts of the equipment. The effect of the infrared treatment regime on the mechanical properties of the F-40S elastomer-based nanocomposite was investigated. The mechanical properties of the elastomeric nanocomposite were assessed by the tensile strength of the films, relative elongation and specific deformation work when breaking the films according to the method of GOST 14236-81, the elastic modulus of the material for tension and compression - according to GOST 9550-81. The optimal mode of infrared processing of the nanocomposite was determined with an active experiment according to the V2 plan. Faulty samples were evaluated according to GOST 9407-84. As a result of regression analysis, a model of the dependence of the specific destruction work of the films of the F-40S elastomer nanocomposite on the infrared treatment mode was obtained. The optimal mode of thermal treatment of the elastomeric nanocomposite is established: 140,00S temperature, time 3.0 hours, at which the material films have the highest specific fracture work of 56.0 MJ/m3. The thermoradiation method, compared to the convective drying method, increases the strength of the nanocomposite films by 1.13 times, from 19.0 to 21.5 MPa. Infrared treatment increases the deformation of samples from 74 to 98%, 1.32 times. The stiffness of the material increased: an increase in the elastic modulus at tension from 158.3 to 161.8 MPa, by 3%, and compression - from 82.7 to 87.2 MPa, by 5.4%. The thermoradiation way, in comparison with a convective way, considerably increases quality of coverings of an elastomeric nanocomposite: the area of the destroyed covering decreases from 20 to 15%, by 1.33 times; concentration of a time in – from 0.67 to 0.54 pieces/cm2, by 1.24 times and the size of a time – from 0.109 to 0.095 mm, for 15%.

Application of polymer coatings for restoration of worn-out bearing holes in housing parts of automotive equipment provides multiple increase of their service life, reduction of repair costs, improvement of reliability. The highest efficiency is achieved by applying elastomeric coatings. To cure the material and achieve high mechanical properties, the coating, after application, is subjected to thermal treatment by convective or thermoradiation methods. Coatings after treatment by a thermoradiation method, in comparison with convective, have significantly lower porosity and higher quality. A model of infrared heating of type I body parts (gearbox housing, car and tractor transfer case housing) has been developed, which takes into account the heat capacity of the material and the design parameters of the part, the ambient temperature and the steady temperature of the part during heating, the design parameters of the infrared radiation installation. The model allows you to calculate the rate of temperature increase and the time of heating the part to the required temperature by infrared heating. The article describes in detail the algorithm and provides a computer program for calculating the structural and technological parameters of the infrared processing plant for elastomeric coatings applied during the restoration of bearing holes in the body parts of the equipment. Heating of the gearbox housings of GAZ-24 and GAZ-53A cars showed a high coincidence of the design and experimental values of infrared heating parameters. The difference between the actual heating temperature of the body part and the design temperature is from 1.5 to 2.4%, the heating time is from 6.1 to 8.2%, which is a confirmation of the correctness of the developed method for calculating the structural and technological parameters of infrared installations. An experimental assessment of the quality of elastomeric coatings after heat treatment by various methods was carried out. Compared to the convective method, after infrared treatment, the quality of elastomer coatings increased F-40S: the area of the destroyed coating decreased by 1.33 times, the concentration of pores in the coating - by 1.24 times.
