A description of the equipment and possibilities of surface morphology analysis on a new profilometer model 130 with a Russian-made nanometer attachment has been given. The analysis of the fracture surface of car steering rod material is carried out by means of the developed methodology for studying the morphology of the breaks of a metal samples with a nanometer resolution. The nature of the fracture is determined as fragile mode I. A fracture core at the composite insert boundary in the steel material of the steering rod was revealed.
