1. 1. Increased build rate by laser powder bed fusion of SSAB steel powder

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Colin Daly; [2023]
   Keywords : Additive manufacturing; Laser powder bed fusion; Build rate; Steel powder;

   Abstract : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. READ MORE

3. 2. Modelling Gas Flow Behaviour in Gas Atomizer

   University essay from KTH/Materialvetenskap

   Author : Aravind Senan Vasanthasenan Reji; [2022]
   Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

4. 3. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

   University essay from KTH/Materialvetenskap

   Author : Mahsa Darvishghanbar; [2022]
   Keywords : ;

   Abstract : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. READ MORE

5. 4. Improving gas flow in gas atomization

   University essay from KTH/Materialvetenskap

   Author : Zhiwei Qiu; [2021]
   Keywords : ;

   Abstract : Gas atomization is a cost-effective processing method to produce fine, spheroidized metal powders. During the process, high velocity jets of gas are sprayed at a molten metal stream to break it into small droplets, which will solidify and form the powder particles. READ MORE

6. 5. Characterization of Metal Powders Produced by Two Gas Atomizing Methods for Thermal Spraying Applications

   University essay from KTH/Materialvetenskap

   Author : Tim Pettersson; [2015]
   Keywords : Powder metallurgy; Gas atomization; Thermal Spraying; Ni-Si-B; Ni-boride;

   Abstract : This thesis work is focused on the influence of process parameters during gas atomization on the thermal spraying properties of a Ni-Cr-B-Si hardfacing alloy. The metal powder alloy, known as 1-60-20, is produced by Höganäs AB. READ MORE
