The article, presents an analysis of the microrelief characteristics of friction surfaces when lubricated with transmission oils containing anti-seizure additives. It explores existing methods for assessing surface quality and evaluates the application of the Abbott curve to analyze the structural adaptation of contact surfaces during friction. The study identifies patterns in the changes to microrelief and wear resistance based on the type of lubricant used.
The research highlights that friction between surfaces during gear transmission operation significantly affects the durability of gearboxes, emphasizing the importance of friction force measurement for predicting seizure resistance and longevity. Traditional assessments of surface roughness, such as average profile deviation (Ra) and maximum profile height (Rmax), are examined in conjunction with the physical and mechanical properties of the surface layer.
The paper discusses the limitations of conventional surface formation technologies, which may not always achieve the optimal combination of microgeometric characteristics and surface properties post-abrasive treatment. The findings underscore that achieving an ideal microgeometry and surface layer properties during the formation stage can lead to a more stable operational state and reduced initial wear period.
The objective of the study is to evaluate the impact of lubricants on the microgeometric parameters of a 30KhGSA steel sample under sliding conditions using a laser scanning differential-phase microscope-profiler.
The findings underscore that achieving an ideal microgeometry and surface layer properties during the formation stage can lead to a more stable operational state and reduced initial wear period.
