| Abstract. | The analysis of structural and tribological materials, geometry and efficiency of working bodies of domestic and foreign construction machinery is given. The results of research performance indicators and road grader blades cutters developed based on strain-topographic method and dual degrees tribodeformative hardening attitude of the golden ratio. There is broad use of heat-treated alloy steel in the manufacture of crowns for attachments bulldozers and excavator bucket teeth on the domestic and foreign manufacturers. Effective use is austenitic steel hardness HV 2400...2700 MPa and austenitic steel hardness of HV 2800...3600 MPa. The expediency of technological design of functionally graded materials, providing a rational combination of opposing properties – hardness and toughness. Shows the relationship of bulk and surface properties of metallic materials, allow you to select structural and tribological steels and alloys purpose. As a result of the performance test grader blades set the maximum temperature on the friction surface at 200-210 °C, the temperature of the wear products 530-540 °C. To select the sound tribological material recommended wurf criterion when it meets golden wurf Wо=1,309. A review of materials and strengthening technologies for construction equipment working bodies showed the effectiveness of wear-resistant weld metal eutectic type. Designed topographical deformation method to determine the basic operating characteristics of the cutting elements in interaction with abrasive media. |
