Ilmuwan Rusia Tingkatkan Kemampuan Teknologi 3D Printing di Sektor Penerbangan


 Periset dari National University of Science and Technology MISIS (NUST MISIS) di Rusia sukses tingkatkan kekuatan tehnologi 3D printing di bidang penerbangan.

Mereka meningkatkan tingkat kekerasan produk 3D printing sejumlah 1,5 kali lipat dengan memakai bahan aluminium.


Perolehan ini karena aditif nanokarbon pada bubuk aluminium, yang sudah mereka bangun. Aditif ini didapat dari produk pemrosesan gas minyak bumi berkaitan yang bisa tingkatkan kualitas komposit 3D printing di bidang penerbangan.


Dalam riset yang keluar di jurnal Composites Communications itu, disebutkan jika program khusus perolehan itu untuk sekarang ini terhitung pengerjaan suku cadang berteknologi tinggi untuk industri penerbangan dan luar angkasa.


Kedatangan cacat sekecil apa saja pada susunan tercetak, penting untuk keamanan tehnologi yang lagi dibikin. Menurut beberapa periset NUST MISIS, resiko khusus cacat itu ialah porositas bahan yang tinggi, yang diantaranya berasal dari kualitas bubuk aluminium asli.


Buat pastikan susunan mikro yang seragam dan padat dari produk cetakan, beberapa periset dari MISIS Catalis Lab menyarankan tambahan serat nanokarbon ke bubuk aluminium. Pemakaian aditif ini bisa menolong pastikan porositas material yang rendah dan kenaikan kekerasannya sejumlah 1,5 kali lipat.


"Mengganti formasi kimiawi dan babak bubuk untuk pembuatan dengan masukkan elemen tambahan ke dalam matriks khusus memungkinkannya kenaikan propertinya," tutur kepala laboratorium sekalian profesor di NUST MISIS, Alexander Gromov diambil dari info tercatat, Kamis (26/11/2020).


Secara eksklusif, kata Gromov, serat nanokarbon mempunyai konduktivitas termal tinggi. Karakter ini bisa menolong meminimalisir gradien temperatur di antara susunan yang diciptakan sepanjang sintesis produk pada step peleburan laser selective.


"Karena ini, mikrostruktur material nyaris bisa seutuhnya di hilangkan dari heterogenitas," papar Gromov.


Studi ini sudah dikerjakan bersama dengan beberapa periset dari Boreskov Institute of Catalysis SB RAS. Di periode kedepan, team periset merencanakan untuk tentukan keadaan maksimal untuk peleburan laser selective dari bubuk komposit baru, dan meningkatkan tehnologi untuk pascapemrosesan dan pemakaian industri produk yang disintesis.
