Evaluation of WC-9Co-4Cr laser surface alloyed coatings on stainless steel

Author: Obadele, A ; Olubambi, PA ; Pityana, Sisa L ; Popoola, API Date: Jul 2011 In order to examine the microstructure and hardness behaviour of WC cermets, coatings have been obtained by laser surface alloying technique. WC-9Co-4Cr particulate was injected onto the surface of AISI 304L austenitic stainless steel (ASS) ... Read more
Hardfacing of aluminium alloys by means of metal matrix composites produced by laser surface alloying

Author: Pityana, Sisa L Date: Jun 2009 Metal matrix composite layers were formed on an aluminium substrate by means of laser surface alloying method. Aluminium 1200 was used as a host material and TiC particles were used as the reinforcement. The microstructure of the modified ... 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
Laser surface alloying (LSA) of aluminium (AA 1200) with TiB2 for hardness improvement

Author: Popoola, AP ; Pityana, Sisa L Date: Oct 2010 The present work deals with the development of Aluminium metal matrix composite (MMC) using TiB2 reinforcement. The aim is to improve the microhardness property of the substrate. The surface of the aluminium was sand blasted to improve its ... Read more
