“…As a result, the comprehensive properties of the substrate such as the combination of the high strength, high toughness, high hardness and high wear resistance may be improved markedly. Therefore, the techniques preparing the ceramic-metal composite coatings have a wide application potential in the fields of the surface repairing of the key components and the three-dimensional rapid manufacturing [1,2]. Now, the techniques preparing the ceramic-metal composite coating mainly include plasma spraying, arc welding, laser cladding and so on.…”

“…The research was also filed as patent [128]. There have been also numerous research methods [131][132][133][134][135][136][137][138] that used pyrometers to monitor and analyze the melt pool or the process zone and infer conclusions about different parameters such as variation in standoff distances or laser defocusing.

There is consensus among both the research and industrial communities, and even the general public, that additive manufacturing (AM) processes capable o f processing metal lic materials are a set o f game changing technologies that offer unique capabilities with tremendous application potential that cannot be matched by traditional manufacturing technologies. Unfortunately, with all what AM has to offer, the quality and repeatability o f metal parts still hamper significantly their widespread as viable manufacturing proc esses. This is particularly true in industrial sectors with stringent requirements on part quality such as the aerospace and healthcare sectors. One approach to overcome this challenge that has recently been receiving increasing attention is process monitoring and real-time process control to enhance part quality and repeatability. This has been addressed by numerous research efforts in the past decade and continues to be identified as a high priority research goal. In this review paper, we fill an important gap in the liter ature represented by the absence o f one single source that comprehensively describes what has been achieved and provides insight on what still needs to be achieved in the field o f process monitoring and control fo r metal-based AM processes.

“…Liu and Li (2004) revealed that the scanning velocity and/or stand-off distance could act as a good compensatory process variable. Zhong et al (2004) suggested that in many cases, it was necessary to in situ monitor the temperature, geometry and standoff between the nozzle and the workpiece and then control the laser power, the powder feed rate and the standoff in order to achieve good quality. These viewpoints have a greatly practical significance.…”
