Abstract
The Titanium-Titanium boride (Ti-TiB) composite was subjected to surface modification using laser surface treatment. A significant increase in surface hardness to 980 VHN, relative to 513 VHN for the untreated material occurred with a laser energy input of about 30 kJ/m, achieved with 20 and 30 mm/s traverse speed. This increase in hardness corresponds to increase in surface volume fraction of TiB whiskers to about 65 % at about 30 kJ/m and above.
