摘要：
In the present study, a high power continuous wave CO(2) laser has been used for development of titanium boride/di-boride dispersed aluminium matrix composite on aluminium, a graded SiC dispersed alpha-Fe matrix composite on mild steel and TiN dispersed alpha-Ti matrix composite on Ti6Al4V. A detailed study of the microstructures and phases developed in the composite layer has been investigated and correlated with process parameters. A significant improvement in microhardness and wear resistance properties was recorded. The mechanism of properties improvement is discussed in detail. (c) 2010 Published by Elsevier B.V.
