Abstract
The solution of universal, global problems of energy and resource conservation in both mechanical engineering and agro-industrial complex are inextricably linked with the solution of issues of protection of machinery from corrosion.
Modern agricultural machinery, and self-propelled combine harvesters in particular, are operated periodically for one or two seasons a year. Most combine harvesters are stored in the open areas of agro-industrial enterprises, and it is exposed to aggressive environmental influences (fluctuations in temperature, humidity, wind, solar radiation, dust and others). The main type of environmental impact on the equipment is atmospheric corrosion and the corrosion wear caused by materials, parts and components, which leads to its premature failure. Thus, the fatigue strength of steel products when stored for 12 months in the open reduces by 28–58%.
To ensure temporary corrosion protection of combine harvesters, a large number of conservation and working-conservation oils are used. However, the unresolved number of issues of theoretical and practical nature leads to the unjustified use of protective equipment, which either does not provide the required duration of storage of equipment, or increase the cost of its preservation. Standardized methods of testing anti-corrosion lubricants in the vast majority have a number of disadvantages, the most important of which is that the evaluation of protective properties is carried out in units that do not allow to estimate their service life, but only show the corrosion of the metal.
