Abstract
.The wear of stainless steel and carbon in coastal and offshore installations has been studied in order to increase the life service of engineering components and reduce maintenance costs. In this sense, the present work aims to present a literature review of different studies of wear behavior of Inconel 625 coatings applied on carbon steel substrate, 304L, 317L, Q235 and AISI 347 through thermally sprayed and hardfacing process to understand the wear behavior and the microstructure formed from the application of different coating techniques by inconel 625 on different substrates. Data was collected related to surfaces coated by Inconel 625 with wear test in saline solution with the objective to understand the influence of the coating process by Inconel 625 and the influence of the substrate on wear. The studies demonstrated that the wear behavior was characterized by means of a pin-on-disk device and abrasion test devices and the tests were carried out in NaCl solutions and DI water. It is observed in the literature that the variations of applied loads and slip speed (SS) had a smaller effect on the wear resistance of Inconel 625, the high hardness of the coating layer and the oxide film on the surface were responsible for the low wear rate. For stainless steel, carbon steel and medium carbon steel substrates, it is observed in the literature the presence in the coating layer of an anti-wear phase that considerably increases the resistance to wear by corrosion of surfaces coated with Inconel 625.
