Results of the Complex Studies of Microstructural, Physical and Mechanical Properties of Engineering Materials Using Innovative Methods

摘要

The article is devoted to the pressing issues of a comprehensive study of the microstructure, physical and mechanical and tribological properties of a heterogeneous system in the surface layer. Study methodology mostly touches upon the processes in the liquid single-and two-phase medium with excitation of ultrasonic vibrations of high intensity and their impact on the study object. In light of the principles of the proposed methodology of micro-level analysis of the microstructure and physical and mechanical properties of construction materials it turns out to be possible to conduct a number of studies. Starting with the metallographic analysis and the study of the microstructure of the modified heterogeneous surface at the same time we can estimate their real relationship to the physical and mechanical properties of the monolayers of material zone under study. Sequential comprehensive analysis of the parameters under study brings out the influence of these factors on a number of important indicators such as erosive wear resistance, adhesive and cohesive robustness and load-bearing capacity of the modified material surface. Proposed research methods can reduce the amount of preparatory and experimental works, and as well significantly improve the reliability and quality of the data. Thus, experiments can be performed in various liquid mediums, simulating various conditions of lubrication and an impact of corrosive environments. In addition to the metallic materials analysis, the technique has found its application in dental practice - study of dental prostheses and restorations.
