In this study, an environmental and economic assessment of WC-Co coatings deposited by Cold Gas Spray (CGS), Atmospheric Plasma Spray (APS) and High Velocity Oxy Fuel (HVOF) spray technologies is carried out. Using SimaPro LCA software, several environmental impact categories are analyzed to compare their environmental performance. The economic analysis includes capital and operating expenditures. The results have highlighted that all three processes exhibit low environmental impact in terms of CO2 emissions but the performance of the CGS process is heavily influenced by the low deformability of WC-Co, while the APS process is affected by high electricity consumption. In terms of economic analysis, the HVOF process exhibits the best performance, while the CGS process requires most time to deposit the coating, and consequently, it is the process where the workforce component is most significant. These results depend on the fact that CGS might not be the most suitable deposition technique for fabricating WC-Co coatings.
在本研究中，对采用冷气体喷涂（CGS）、大气等离子喷涂（APS）和高速氧燃料（HVOF）喷涂技术制备的WC-Co涂层进行了环境和经济评估。使用SimaPro生命周期评价软件，分析了几个环境影响类别以比较它们的环境性能。经济分析包括资本和运营支出。结果表明，所有这三种工艺在二氧化碳排放方面都表现出较低的环境影响，但CGS工艺的性能受到WC-Co低变形性的严重影响，而APS工艺则受到高电耗的影响。在经济分析方面，HVOF工艺表现出最佳性能，而CGS工艺沉积涂层所需时间最长，因此，在该工艺中劳动力成本占比最大。这些结果取决于CGS可能不是制备WC-Co涂层最合适的沉积技术这一事实。
