A Study on an Evaluation Method of Eco-efficiency of a Diamond Coating Process

摘要

Since one of the most important goals of sustainable manufacturing is to obtain high eco-efficiency. One of the authors has proposed a new eco-efficiency type index called "total performance indicator (TPI)." In order to evaluate TPI of manufacturing processes, an evaluation method of manufacturing quality is indispensable. Diamond coatings to substrates are important manufacturing processes having wide varieties of applications. The developed coating process can be carried out by using compact and low cost set-up. In the paper, the authors use the new diamond coating process for a case study. Throughout the evaluation of the quality characteristics, costs and environmental impacts of the process, the paper tries to say that the new diamond coating process can be an eco-efficient method.
