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.Keywords

This paper attempts at a review of the recent developments on the improvement of surface corrosion in titanium alloys and composites by various surface treatment techniques. The surface treatment techniques include different types of laser surface coating, plasma enhanced vapour deposition, high intensity plasma beam coating, cathodic are deposition and reactive magnetron sputtering. Also the effect of laser surface treatment on Ti-TiB composite and its corrosion resistance properties were reviewed. The possibility of laser surface modification of Ti-TiB composite surface for enhancement of corrosion properties was also reviewed and discussed.Keywords
