COMPARISON OF CHARACTERISTICS OF METAL POWDER COMPOSITIONS OF VZHL718 ALLOY PRODUCED BY PREP AND VIGA METHODS IN THE PROCESS AFTER SELECTIVE LASER MELTING
View through CrossRef
В работе были изготовлены четыре металлопорошковые композиции сплава ВЖЛ718 (IN718): одна по технологии вакуумной индукционной плавки и газового распыления (VIGA) и три по технологии плазменной плавки и центробежного распыления вращающейся заготовки (PREP). Были исследованы их гранулометрические составы, параметры распределения, технологические свойства, влажность и содержание газовых примесей исходныхметаллопорошковых композиций VIGA и PREP. Показаны и проанализированы различия между металлопорошковыми композициями VIGA и PREP, даны пояснения выявленных различий. Проведено четыре процесса селективного лазерного сплавления с применением исследованных металлопорошковых композиций VIGA и PREP. Исследованы гранулометрические составы, параметры распределения и технологические характеристики МПКVIGA и PREP после однократного применения в процессе селективного лазерного сплавления, выявлены различия между изменениями характеристик и гранулометрических составов металлопорошковых композиций VIGA и PREP. Даны пояснения о причинах выявленных изменений металлопорошковых композиций VIGA и PREP после селективного лазерного сплавления и о взаимосвязях с исходными характеристиками МПК. Сделаны выводы и заключения о дальнейшей возможности повторного использования металлопорошковых композиций VIGA и PREP после селективного лазерного сплавления.
In this work four metal powder compositions of VZL718 (IN718) alloy were produced, one by vacuum induction melting and gas atomization (VIGA) technology and three by plasma melting and centrifugal rotating billet atomization (PREP) technology. Their particle size distributions, distribution parameters, technological properties, moisture content and gas impurity content of VIGA and PREP initial metal powder compositions were investigated. The differences between metal powder compositions VIGA and metal powder compositions PREP were shown and analyzed, and the differences were explained. Four selective laser melting processes were carried out using the investigated VIGA and PREP metal powder compositions. The particle size distributions, distribution parameters and process characteristics of metal powder compositions VIGA and metal powder compositions PREP after a single application in the selective laser melting process were investigated, and the differences between the changes in the characteristics and particle size distributions of VIGA and PREP metal powder compositions were revealed. The reasons for the identified changes in metal powder compositions VIGA and metal powder compositions PREP after selective laser melting and the relationships with the initial metal powder compositions characteristics are explained. Outputs and conclusions about further possibility of reuse of VIGA and PREP metal powder compositions after selective laser melting are made.
