Web摘要： Due to the high melting point and high heat conductivity, selective laser melting (SLM) of tungsten is still challenging. To have a better understanding of SLM tungsten parts, the effects of processing parameters such as laser power and scanning speed on scanning tracks formation of pure tungsten powder were investigated. WebSelective laser melting of pure copper is challenging because of its high optical reflectivity and thermal conductivity. Accordingly, the surface of pure copper powder was modified by oxidation to enhance the optical absorption. The pow-der with improved optical absorption facilitated the production of crack‐free

WebPure copper is utilized as a material for products with complicated shape and high thermal conductivity such as heat exchangers. However, it is difficult to fabricate pure copper parts with high density by the selective laser melting (SLM) process. Webheat exchangers. However, it is difficult to fabricate pure copper parts with high density by the selective laser melting (SLM) process. One of the reasons is considered to be its high thermal conductivity by which the heat in the melt pool rapidly diffuses away. Additionally, the lower rate of energy absorption of fiber laser power for pure ... WebFeb 1, 2016 · In this work the selective laser melting (SLM) of pure copper powder was studied. Because of low laser radiation absorption and high thermal conductivity it is very … ramon ayala christmas lights
