Abstract
The purpose of this research is to study the metallographic analysis optimization of the T6-treated forging Al alloys, 7075, 6061, and casting Al alloy A356 for medical equipment parts. The influences of the metallographic image under several control factors, types of polishing solution, etching time, polishing speed, etc., are investigated. Taguchi method is employed to evaluate the optimization of aluminum alloy metallographic analysis. By using Matrox Inspector 4.0 image analysis software, the metallographic images are converted to gray scale. According to the gray scale values, the major factor of the metallographic image optimization for Al alloy 7075 and 6061 is the etching time, while the polishing speed is the least control factor. For Al alloy A356, the type of polishing solution is the main factor for the optimization of metallographic image, while the least influential factor is the etching time. The optimized metallographic factors combination can be used on the development and design of the medical equipment parts in the future.
