1 Introduction

Al was used as matrix material SiC with amount of 0 3 0 6 and 0 9 vol % respectively was used as the reinforcement in the composites The powders were blended for 30 min using high-energy ball mill with the rotation speed of 200 rotations per minute (rpm) At this stage no Get price



Aluminium dross consists mostly of alumina (Al2O3) silicon oxide (SiO2) and aluminium nitride (AlN) The raw materials were mixed and milled using the high energy ball milling method for 5 10 and 15 minutes in order to reduce the particle size The milled powders were uniaxially pressed into a cylinder die with the pressure of 2200 psi Get price



The focus of this paper is on the development of additive manufacturing methodologies specifically for complex BPP designs These low-cost manufacturing schemes combine the ability of 3D (3DP) to generate complex patterns with thermal spray technologies that can deposit a variety of functionally designed metallic materials Get price
