Effect of minor elements on solidification cracking and dilution of alloy 625 powders in laser cladding
Abstract
The general specification of nickel-base alloy 625 is quite permissible allowing relatively large variations in chemical composition. In directed energy deposition processes including laser cladding and additive manufacturing, the powder plays a key role in the properties of final products. Therefore, it is important to select the highest-quality powder. Several commercially available alloy 625 powders were characterized and deposited on mild steel by the laser cladding process using a coaxial powder feeding method and a single bead. Clad layer characterization consisted of determination of dilution and quantification of hot cracks. The results showed that powders containing the lowest amount of impurity elements (S, P, B) were the most resistant to hot cracking. Ti and Al were beneficial if impurity element contents were high.
