Evaluation of Physical and Mechanical Properties of the Hardfacing Reinforcement Zone of Deep Riper Chisels Depending on the Technological Schemes

Abstract

The paper discusses methods for increasing the operational durability of Vaderstad deep riper chisels by hardfacing reinforcement of the working and back surfaces. Two variants of hardfacing geometry have been studied: ladder and herringbone. Hardness measurements of the chisel metal and the hardfaced beads have been carried out using various electrode materials. It has been established that hardfacing slightly reduces the hardness of the base metal. The results of a comparative analysis of the hardness of the hardfaced layers are presented, and the features of property changes when using different hardfacing technologies are identified.
