Abstract
The gas dynamic spray process is studied via acoustic methods with the main focus being on developing an online system to monitor the process as it occurs. Elastic modulus measurements of the coatings are determined from the sound velocity and porosity. The resulting data is than compared against a minimum contact area model that is developed to describe the bonds that are formed between particles. The results show a good fit to the theoretical considerations of the model. Different transducer designs are considered leading to the use of a multi-element flat transducer for the online monitoring. Online measurements show that the build-up of the coating can be directly seen as well as accurate profiles of the coating created. Finally the online results are shown to be able to accurately predict thickness measurements of the coating acoustically.
