Testing of heat-treated surfaced samples and machine parts for hardness and wear resistance

In this article, the chemical and mechanical properties of some parts of machine mechanisms made of steel 35 are studied, as well as their resistance to abrasive wear. In addition, casting samples with corrosionresistant surface coating obtained by casting are considered. The samples of steel material obtained as result of experimental studies and their resistance to corrosion in terms of hardness are presented using tables. The finished parts were tested for abrasive wear resistance in the field. Optimal modes of heat treatment with double phase recrystallization for parts of tillage machines have been applied. It is proved that the optimal heat treatment with double phase recrystallization increases the hardness and wear resistance of cast samples and finished parts by 2-3 times.
