  • Mabhali, Luyolo AB; Pityana, S; Sacks, N (IJEATR: International Journal of Engineering and Technology Research, 2013-08)
    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 ...
  • Mabhali, Luyolo AB; Sacks, N; Pityana, S (Elsevier, 2012-03)
    Laser surface alloying of aluminium AA1200 was performed with a 4kW Nd:YAG laser and the impact resistance of the alloys was investigated. The alloying powders were a mixture of Ni, Ti and SiC in different proportions. ...
  • Mabhali, Luyolo AB; Pityana, SL; Sacks, N (2010-07)
    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 ...

    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, ...
  • Mabhali, Luyolo AB; Pityana, S; Sacks, N (PICALO 2010, 2010-03)
    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 ...

  • Mabhali, Luyolo AB; Pityana, SL; Sacks, N (Taylor & Francis, 2010-12)
    An Nd:YAG laser was used for surface alloying of aluminum AA1200. The alloying powder was a mixture of Ni and SiC in different ratios. A study of the microstructures obtained after alloying was conducted using optical and ...
  • Mabhali, Luyolo AB; Sacks, N; Pityana, S (Elsevier, 2012-06)
    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. ...
