摘要

Laser powder bed fusion (LPBF) of metal matrix composites (MMC) is a popular additive manufacturing technique due to its design flexibilities, reduced waste, improved properties, and shorter fabrication lead times. However, in order to enhance the related performance, a number of essential factors are to be carefully considered to make the product get up to standard. Significant advancements have been made in the application of this fabrication method, and the present paper focuses on the use of metal matrix composites (MMCs), with particular emphasis on silicon carbide (SiC)-reinforced aluminum matrix composites (AMCs). This paper commences with a review of the AMCs with the objective of summarizing the LPBF process issues and main failures using quality management tools, thereby simplifying the understanding of the process for easier failures Root-Cause Analysis (RCA). Then, quality management tools such as the Ishikawa standpoint, 5-whys analysis, and SWOT matrix were exploited to interpret the methodologies involved in the LPBF, come up with root causes of possible defects and anomalies during fabrication, and find the advantages, opportunities, and possible threats associated with the fabrication of AMC using LPBF, respectively; risk insight was formally assessed by adopting Fault Tree Analysis (FTA) and Failure Mode Effects and Criticality Analysis (FMECA); the proposed approach results in determining the most prominent failures in terms of failures mechanism developments (FTA) and Pareto/ABC classification of the FMECA criticality. Furthermore, a systemic scheme was proposed to better understand the process and risk exposition using an optimization loop for illustrating the areas of multi-criteria and multi-optimization niches as an integrated high-order system.
