Abstract
Induction surfacing is applied in manufacture and repair of cutting tools of agricultural machinery. Deposited layers improve the tool wear resistance. Here it is important to take into account the deposited layer thickness. The paper presents the results of investigation of geometrical characteristics of a layer of metal deposited by induction process with wear-resistant powder-like consumables by four technological schematics. It is shown that application of shields, horizontal vibration and rotation of the surfaced part improves the stability of geometrical characteristics of the deposited metal layer by 22 %, compared to traditional induction surfacing. A procedure was developed for measurement of geometrical characteristics of the metal layer deposited by induction process, which allows increasing the measurement accuracy, as well as monitoring the stability of layer thickness at development of new technological processes of induction surfacing of thin flat parts. 8 Ref., 3 Figures.
