ABSTRACT

This study aims to analyze the influence of parameters on Abrasive Water Jet Machining of aluminum (AA6063) composites reinforced with bagasse ash and titanium nitride particles. Bagasse ash and titanium nitride were reinforced in the aluminum alloy by the stir casting technique. Mathematical equations were derived by response surface methodology and the results were analyzed by ANOVA technique. The material removal rate and surface roughness were studied by varying the traverse speed, standoff distance, bagasse ash and titanium nitride. Characterizations of the machined surfaces were analyzed using scanning electron microscopy and atomic force microscopic study. Material removal rate and surface roughness are primarily influenced by standoff distance followed by traverse speed and titanium nitride particles. Microstructure reveals erosion mechanisms in the form of plowing, ridges, cavities, micro-cracks, tearing, deformation, etc. The abrasive machining results and optimization provides a database for various industrial applications.

摘要

本研究旨在分析参数对用甘蔗渣灰分和氮化钛颗粒增强的铝（AA6063）复合材料进行磨料水射流加工的影响。通过搅拌铸造技术在铝合金中增强了甘蔗渣灰分和氮化钛。通过响应面法推导出数学方程，并通过方差分析技术对结果进行分析。通过改变横动速度、间隔距离、甘蔗渣灰分和氮化钛来研究材料去除率和表面粗糙度。使用扫描电子显微镜和原子力显微镜研究分析加工表面的特征。材料去除率和表面粗糙度主要受间隔距离的影响，其次是移动速度和氮化钛颗粒。
