Impact toughness of laser alloyed aluminium AA1200 alloys

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: Aug 2013 Laser surface alloying of aluminium AA1200 was performed with a 4kW Nd:YAG laser and impact resistance of the alloys was investigated. The alloying powders were a mixture of Ni, Ti and SiC in different proportions. Surfaces reinforced with ... Read more
Improvement of the surface properties of aluminium by the formation of intermetallic phases and metal matrix composites during laser surface alloying

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: May 2011 Aluminium is widely used in industry due to its low cost, light weight and excellent workability, but is lacking in wear resistance and hardness. Laser alloying is used to improve the surface properties, such as hardness, by modifying the ... Read more
Three body abrasion of laser surface alloyed aluminium AA1200

Author: Mabhali, Luyolo AB ; Sacks, N ; Pityana, Sisa L Date: Jun 2012 Laser surface alloying of aluminium AA1200 was performed with a 4 kW Nd:YAG laser to improve the abrasion wear resistance. Aluminium surfaces reinforced with metal matrix composites and intermetallic phases were achieved. The phases present ... Read more
