A review on the presence of lasers in the processes of coating, repair, and prototyping

The aim of this study is to provide the characteristics of laser cladding and its application in three areas of coating, repair and prototyping. Among the innovations of this research, we can compare the features and advantages of laser coating with other conventional methods such as tags, etc. by mentioning sample studies. Also, the study of the areas of coating, repair / reconstruction and prototyping of laser coating with mentioning an objective industrial example in order to understand the exact application of other innovations of the present study is considered. In other words, the innovation of this research is the presentation of features and application of laser coating in three areas of coating, reconstruction and prototyping of industrial parts in comparison with other methods that were not addressed in a study. In this regard, the benefits of this technology will be presented first. Details of the laser coating process of the brake discs are given. How to repair the gas turbine fuel nozzle and rebuild the locomotive engine body by laser method will also be introduced. A prominent example of laser prototyping is the production of a helicopter engine combustion chamber. For a better understanding, a comprehensive overview of previous studies will be provided. Finally, the speed and capabilities used in each of the three areas of coating, reconstruction and laser prototyping are introduced.
