Abstract

In this paper, laser cladding of Inconel 713 LC was performed by using Metco 81VF powder and 400 W pulsed Nd:YAG laser. The effect of laser parameters including laser frequency, pulse width, and laser scanning speed was investigated on the microstructure characteristics and microhardness of coating. The results showed that by increasing the laser frequency and pulse width or decreasing the laser scanning speed, the heat input increases and therefore, the resultant dilution ratio raises. The clad zone of the samples with a high dilution ratio consists of a eutectic structure (γ and Cr7C3). However, the clad zone of specimens with a low dilution ratio is composed of a hypereutectic structure of Cr7C3+(γ+Cr7C3). Increasing the laser frequency and pulse width (increasing the dilution ratio and removal of primary carbides in the microstructure) causes the decrease in microhardnes of the clad zone, but increasing the laser scanning speed has an opposite effect and causes the increases in microhardness of the clad zone. The optimal sample was selected with a laser frequency of 18.4 Hz, a pulse width of 11.2 ms and a laser scanning speed of 2.8 mm/s. This sample, in addition to the acceptable dilution ratio and appearance, has a remarkable hardness of 1204 Vickers, which is about 3 times the hardness of the base metal.
