Effect of process control agent and mechanical milling on the embedment and uniform dispersion of CNTs and B4C in aluminium matrix

Abstract

Using lighter materials like Aluminium(Al) is also a common practice for producing prosthetic devices. This method not only provides less weight but also gives freedom to the designer to design customized devices. But Al can not be used in its pure form as it lacks strength, toughness, rigidity. A common way to overcome these issues is the use of composite materials.In this paper, we have studied how mechanical milling can be used to disperse hard ceramic particles and Carbon nanotube homogenously in Al matrix. We have also demonstrated how changes in different process parameters affect the properties of this composite and how a uniform dispersion can be achieved by the use of the specialized technique. In this paper, we have also suggested methods to avoid clustering and cold welding of reinforcements.
