Tokmin A. M., Svechnikova L. A., Masansky O. A. — Characteristic interrelation between inductive surfacing and pad structure and properties

Analyzed the processes occurring during melting and crystallization of the deposited powder sormayta, factors influencing the formation of physical and mechanical properties of the product as well as an attempt to formalize the functional relationships using regression analysis. Conducted metallographic studies and power dispersive analysis of the transition zone and deposited layer. Establish a pattern of change of wear on the rate of deposition, as well as hardness and thickness of the deposited layer. It is shown that for high wear resistance of deposited layers is necessary to use a multilayer deposition.
Key words: melting, crystallization, sormayt, physical and mechanical properties

Volkov S. S. — Brush componentry ultrasonic welding schedule

It is established that welding rate of brush-type elements increases when critical parameters of the welding conditions are increasing. Double-faced ultrasonic weld with seam melt formation into profile thickening fit for the brush holder groove is suggested. It is shown that fibre tear-out force out of the brush is higher at the double-faced brush welding than that at the single-faced one. This indicates that brush double-faced welding results show great stability.
