Improvement of hardness of aluminium AA1200 by laser surface alloying

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: Jul 2010 Aluminium is vastly used in industry due to its low cost, light weight and excellent workability, but lacks in wear resistance and hardness. Laser alloying is used to improve the surface properties such as hardness by modifying the composition ... Read more
Laser alloying of AI with mixed Ni, Ti and SiC powders

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: Mar 2010 Laser alloying of aluminium AA1200 was performed with a 4.4kW Rofin Sinar Nd:YAG laser to improve the surface hardness. Alloying was carried out by depositing Ni, Ti and SiC powders of different weight ratios on the aluminum substrate. The ... Read more
