Abstract
The aim of this study was to study the properties of 1201 aluminum alloy after ultrasonic treatment and their evolution during subsequent ion implantation using the monotectic Cu-Pb alloy as the cathode material of the implant. It is shown that during ultrasonic treatment the surface layer of aluminum alloy 1201 undergoes significant changes. A nanocrystalline structure with a grain size of less than 200 microns is formed in it. Ultrasonic treatment of the surface of the target from alloy 1201 before implantation leads to a decrease in the depth of penetration of ions to 160–180 nm and the appearance of amorphization in the implanted layer.
Highlights
Significant progress in the development of the fundamental foundations of ion implantation in recent decades has been achieved thanks to intensive research in the field of modification of the properties of metallic materials
The level of properties of the surface layer obtained as a result of irradiation depends on the mode and types of introduced ions, and on the initial state and level of properties of the target surface before implantation
The deformation of the surface layer is performed by an acoustic head oscillating with an ultrasonic frequency, into which a carbide indenter is soldered
Summary
Significant progress in the development of the fundamental foundations of ion implantation in recent decades has been achieved thanks to intensive research in the field of modification of the properties of metallic materials. Ultrasonic processing (RCD) is an advanced technology for finishing and hardening of metals by pressure, allowing you to replace the classical static methods of PPD according to the schemes of rolling and sliding - rolling and smoothing [4,5,6,7]. Due to the influence of ultrasonic vibrations, the resistance of the metal to plastic deformation is significantly reduced. To achieve the maximum hardening effect, combined processing methods are used [8]
