Abstract
The material of the deteriorated poly-V pulleys made of cold-rolled steel strip 08kp and 08ps was studied using electron microscopy with an X-ray microanalyzer and the causes of their fatigue failure were determined. The main reasons for their destruction can be heterogeneous structure and properties and non-optimal mode of annealing and, as a result, the low hardness on the transitional zone of the pulley, through which they are damaged in service. So, to avoid pieces deterioration, cold-rolled tape made of 035Yu steel with a homogeneous structure and properties was developed. The study also proposes a new mode of its recrystallization annealing, which increases the hardness at the transition zone of the poly-V pulley and the service life of promising automotive generators.
