In the petroleum industry, harsh working environments can cause premature equipment failure due to mechanical wear, corrosion, erosion-corrosion, and other factors. Directly replacing the key parts of equipment is expensive. Laser additive manufacturing technology can be applied to maintain high-performance key components and rapidly repair damaged equipment. This book introduces the methods and processes of laser additive manufacturing technology for application in the oil and gas fields, and it describes the microstructure, corrosion, wear, erosion-corrosion behavior, and mechanism of component or coating fabricated by this technology. Explains the structural properties and various behavioral mechanisms of laser additive manufacturing metals Offers unique coverage of a cost-effective and sustainable solution Features an interdisciplinary approach that can be extrapolated to other industriesThis book is aimed at engineers and researchers working in the oil and gas industry as well as readers seeking a deeper dive into the science and technology of laser additive manufacturing of metals.
