title = "Effect of number of laser scans on the corrosion behavior of laser formed Titanium alloy",
abstract = "This paper reports the investigation conducted on the corrosion behavior of laser formed Titanium alloy (Ti6AI4V). The Titanium alloy sample strips of 1 ×90 × 30 mm3 were laser formed with the following process parameters; laser power (800 W), beam diameter (12 mm) and scanning speed (0.03 m/min) and the number of scans were varied between 3 to 7. The laser formed samples were characterised through the microstructure, hardness and the corrosion behaviour. The visual inspection conducted on the laser formed samples revealed a de-colouration on the samples mostly along the laser tracks. The microstructural evaluation and the grain size measurements were conducted to establish the evolution of the properties of the formed samples. The microstructure of the formed sample was observed to be martensitic in nature compared to the equiaxed microstructure observed in the as-received material. Furthermore, microcracks were also observed in the heat-affected zone. The microcracks observed on the surface of the formed samples revealed that the length of the cracks increases with the number of laser scans. The grain sizes were observed to decrease with the increasing number of laser scans. It was observed that as the number of laser scans increases, the corrosion properties became enhanced.This paper reports the investigation conducted on the corrosion behavior of laser formed Titanium alloy (Ti6AI4V).
