Revealing the technological modes range for ultrasonic surface hardening of cast iron

Abstract

Prospects of using the ultrasonic surface hardening of different materials as a way of achieving a simultaneous strengthening and finishing effects are presented. It is shown that this method is applicable for non-rigid and brittle parts. Thus, it allows processing gray cast iron. Therefore, the paper is devoted to establishing technologically significant parameters of ultrasonic surface hardening of particular gray cast iron. Research was conducted using mathematical modeling of the process. According to the calculations, the application of the modes revealed makes it possible to achieve the depth of the hardened layer up to 2 mm. Moreover, the parameters of the hardened layer, such as the diameter of a single imprint and the maximum intensity of deformation for specified processing conditions are calculated.
