Functional graded materials (FGMs) are a class of composite materials that have a continuous variation of properties from one point to another. FGMs are not new but they could be an approach for eliminating the sharp interface between clad and substrate in the laser cladding process. It is possible to relieve stress concentration appearing in these laminate...$28.00

The delivery of powder to the melt pool via the nozzle is a crucial element at laser material deposition. It has a major influence on the consumption of powder material and the quality of the coating layer. In order to ensure consistently high process stability and quality, it is necessary to check the powder gas stream a...$28.00

Today, Laser Additive Manufacturing (LAM) is typically performed using a single beam with power up to multiple-kilowatts. The associated high heat input and limited process control hampers tight manufacturing tolerances and the applicable material spectrum. This paper highlights the development of Multi-Beam LAM technology to alleviate s...$28.00
