本文主要研究内容
作者（2019）在《Investigating the surface integrity of aluminium based composites machined by EDM》一文中研究指出：In the present work, the surface characteristics of Electrical Discharge Machined（EDM） Al（6351）- SiC and Al（6351）-SiC-B4C composites are investigated. The composites are prepared by employing the conventional stir casting technique, as it can produce better particle dispersion in the matrix. The detailed experimental study is performed on the composites by varying current（I）, duty factor（t）, pulse on time(Ton), and the gap voltage（V） in order to analyze the Heat Affected Zone（HAZ） formed in the sub surface and the average crater diameter formed on the machined surface of the composites as an output function. The formation of recast layers, presence of bubbles and the surface texture of the composites at various machining conditions are observed. The results show that the increased Metal Removal Rate（MRR） increases the depth of HAZ and the average crater diameter on the machined area. Further, the addition of B4C particles to the composite produces more surface defect than the Al- SiC composite.
Abstract
In the present work, the surface characteristics of Electrical Discharge Machined（EDM） Al（6351）- SiC and Al（6351）-SiC-B4C composites are investigated.

The detailed experimental study is performed on the composites by varying current（I）, duty factor（t）, pulse on time(Ton), and the gap voltage（V） in order to analyze the Heat Affected Zone（HAZ） formed in the sub surface and the average crater diameter formed on the machined surface of the composites as an output function. The formation of recast layers, presence of bubbles and the surface texture of the composites at various machining conditions are observed.
