Effect of Compaction Aspect Ratio on Wear Characteristics of Sinter Extruded Pure Copper Processed Through Powder Metallurgy Route

摘要

Powder metallurgy is widely used, unique manufacturing process resulting in a near-net shape. The parameters like, the compaction pressure, aspect ratio (height to diameter ratio), sintering conditions can be varied in order to achieve the required properties of the end product. In this research work, all the above parameters except the aspect ratio are fixed. Wear analysis is carried out on sinter-extruded copper samples are made for two different aspect ratios, i.e., 0.5 and 1. The experiments are conducted based on Taguchi's L18 orthogonal array by taking the aspect ratio, speed, and load as three important factors. The mass loss and COF (coefficient of friction) are the main results studied in this work and are supported by hardness and density measurements.
